The objective of this study is to realize high-speed and high-accuracy electrical discharge machining (EDM) of micro holes using a combination of a conventional EDM machine and a maglev local actuator. In this paper, the conventional EDM machine and the wide-bandwidth, high-precision, 5-DOF controlled maglev local actuator are combined and cooperatively controlled. Then to accelerate the debris ejection from the machined holes, the driving methods of the axial jump and radial vibration of the electrode are discussed. The experimental results show that the maglev local actuator can adjust the gap between the electrode and a workpiece speedily, and the machining speed is improved by 434.2%, compared with conventional EDM machine. Moreover, by the jump and the circular motion of the electrode, the debris ejection can be accelerated, the abnormal electrical discharge can be avoided, and the machining speed also is improved by 580.3%.

Purpose – The purpose of this paper is to give a simple, fast and universal inductance calculation approach of slotless-winding machines and comparison of inductances of toroidal, concentrated and helical-winding machines, since these winding types are widely used among low-power PM machines. Design/methodology/approach – Harmonic modeling approach is applied to model the magnetic field of the windings in order to calculate the synchronous inductances. The method is based on distinction between electromagnetic properties of different regions in the machine where each region is represented by its own governing equation describing the magnetic field. The governing equations are obtained from Maxwell’s equations by introducing vector potential in order to simplify the calculations. Findings – Results of the inductances of toroidal, concentrated and helical-winding slotless PM machines, which have the same torque and dimensions, obtained by the proposed analytical method are in good agreement with 3D FEM, where the relative difference is smaller than 15 percent. However, the calculation time of the analytical method is significantly less than in 3D FEM: seconds vs hours. Additionally, from the results it is concluded that the toroidal-winding machine has the highest inductance and DC resistance values among considered machines. Helical-winding machine has lowest inductance and DC resistance values. Inductance of concentrated-winding machine is between inductance of helical and toroidal windings; however, DC resistance of the concentrated windings is comparable with resistance toroidal windings. Originality/value – In this paper the inductance calculation based on harmonic modeling approach is extended for toroidal and helical-winding machines which makes the method applicable for most of the slotless machine types.

Abstract Magnetic-geared permanent magnet (MGPM) electrical machine is a new type of machine by incorporating magnetic gear into PM electrical machine, and it may be in operation with low-speed, high-torque and direct-driven. In this paper, three types of MGPM machines are present, and a quantitative comparison among them is performed by finite element analysis (FEA). The magnetic field distribution, stable torque and back EMF are obtained at no-load. The results show that three types of MGPM machine are suitable for different application fields respectively according to their own advantages, such as high torque and back EMF, which form an important foundation for MGPM electrical machine research.

Purpose – The purpose of this paper is to optimize the stator slot geometry of a high-speed electrical machine, which is used as an assist for a turbocharger. Meanwhile, the suitability of the Particle Swarm algorithm for such a problem is to be tested. Design/methodology/approach – The starting point of the optimization is an existing design, for which the Particle Swarm algorithm is applied in conjunction with the transient time-stepping 2D finite element method. Findings – It is found that regardless of its stochastic nature, the Particle Swarm work well for the optimization of electrical machines. The optimized design resulted in an increase of the slot area and increase of the iron loss, which was compensated by a dramatic decrease in the Joule losses. Research limitations/implications – The optimization was concentrated on the stator design whereas the rotor dimensioning was carried out withing the compressor and turbine design. Originality/value – A turbocharger with electric assist is designed optimized and manufactured. The Particle Swarm algorithm is shown to be very stable.

Purpose Permanent magnet (PM) electrical machines are becoming one of the most popular type of the machines used in electrical vehicle drive applications. The main drawback of permanent magnet machines, despite obvious advantages, is associated with the flux control capability, which is limited at high rotor speeds of the machine. This paper aims to present a new arrangement of permanent magnets and flux barriers in the rotor structure to improve the field weakening control of hybrid excited machines. The field weakening characteristics, back-emf waveforms and efficiency maps of this novel machine have been reported. Design/methodology/approach In the study, finite element analysis was used to perform simulation research. Then, based on the simulation studies, an experimental model was built. The paper also presents selected experimental results. Findings Obtained results show that the proposed machine topology and novel control strategy can offer an effective flux control method allowing to extend the maximal rotational speed of the machine at constant power range. Practical implications The proposed solution can be used in electric vehicles drive to extend its torque and speed range. Originality/value The paper presents original design and results of research on a new solution of a hybrid excited machine with magnetic barriers in a rotor.

Switched reluctance motor (SRM) is attracting the scientific community in recent days because of its special structural benefits. Good research work has been conducted on this machine since the ages. It has evolved as an alternative to the conventional electrical machines in variable speed drives due to rugged architecture, high-speed operation, four quadrants, lack of magnet, and adaptability to harsh surroundings. This paper reviews different topologies of SRM for electric vehicle (EV) application and a comparative study of suitable machines for electric vehicle propulsion. This paper elaborates on the design methodology and the analysis of various phases of operation of SRMs. During the design procedure, the finite element method (FEM) of optimization is used to enhance motor performance. In this study, the three different phase (3, 4 6) motors are analyzed in machine design software and finite element analysis outcomes and SRM simulation approach are discussed.

This work has analysed, designed, commissioned and validated the performance of a novel cooling system for an innovative high speed, three-phase synchronous permanent magnet machine designed for an aero-engine starter/generator with a power rating of 45 kW and maximum speed of 32,000 rpm. The cooling system designed consisted into inserting a 1 mm non-electrically conductive stator sleeve in the machine airgap, this separates the rotor region from the stationary components letting the rotor running dry at all times; the stator region can then be flooded with oil. Oil enters from one side of the machine through some radial openings impinging directly over the end-winding, it then flows through two rows of equally sized axial ducts located along the inner and outer diameter of the stator to give an even distribution of the coolant, and finally it flows over the surface of the rear end-winding and leaves the machine. The thermal modelling was carried out by the joint use of Computational Fluid Dynamics (CFD) and Lumped Parameter Thermal Network (LPTN); this allowed the investigation of heat transfer phenomena and the optimisation of the cooling design. CFD was primarily employed to investigate the fluid flow and to perform conjugate heat transfer analyses; these allowed the determination of heat transfer coefficients and the prediction of temperature distribution inside the machine. Thermal networks were developed to investigate the heat flow through machine components, to perform the design optimisation and to maximise overall machine performance. A thermal network was also developed by the author to investigate the heat transfer phenomena inside the bearing chambers. An experimental apparatus was designed and commissioned in order experimentally validate the thermal models developed. Temperatures, pressures and torque up to 20,000 rpm were recorded throughout the tests and data collected were compared to quantities predicted analytically and numerically. Maximum winding temperatures measured performing a short circuit test agree well with analytical and numerical prediction with a maximum difference of 10%; mechanical losses measured carrying out a no-load test agree well at speeds over 10,000 rpm with differences between 2 and 12%. Throughout tests, pressure drops were monitored across the machine and an agreement of 13% with prediction were achieved. Design improvements are also proposed to further enhance the cooling of stator slots and of rotor components.

This thesis describes the work done during the several stages of the design, analyse, manufacture and test of a high speed synchronous reluctance machine capable of delivering 5 kW at 80 krpm. In order to meet such demanding speed requirement, several multi-disciplinary design exercises have been carried out having different aims. First the influences of the speed-dependent limiting factors on the machine performance have been investigated by analytical methodologies. After the preliminary analytical design, the main challenges related with the structural and electromagnetic FE-based design refinements have been identified. A comparative study has been then presented with the purpose of identify the most effective rotor design approach in terms of performance of the final design and computational effort related for its achievement. Once the design strategy has been chosen, the advantages of considering rotor parametrization of increasing complexity are evaluated via a comparative study showing the results of several structural optimizations. This study indicated the optimal geometry to manufacture. Prior to the machine prototyping, the influence of the rotor manufacturing tolerance as well as the thermal limitations on the machine performance have been deeply analysed. Tests carried out on the prototype have essentially validated the proposed design approach. In addition, an investigative study aimed at identifying and understanding the reasons of the found discrepancy between the measured and expected performance is also reported.

Solid rotor induction machines are suitable for applications which require robustness, reliability and high rotational speed. A literature review of high speed technologies is initially presented. The current limitation and challenges are detailed based on a wide collection of data. The multi-physics aspect related with electrical machines for high speed applications are discussed providing a summary of the current state of the art. The main aim of the research was to develop a multi-physic computational environment for the design and analysis of solid rotor induction machines. The electromagnetic, thermal, structural and rotor dynamics models have been developed targeting reduced computational time and accurate predictions. Numerical techniques are proposed based on the discretisation of the computational domain. The different disciplines are linked together providing a flexible and powerful tool for the characterisation of solid rotor induction machine. Another objective was to investigate the impact of the rotor material on the electromagnetic performances of the machine. Finite Element simulation are used to account for the non linear magnetic properties. The impact on the equivalent circuit parameter is discussed and general criteria for material selection presented. Three dimensional finite element calculation are p erformed targeting the validation of the end region correction factor and select the rotor length. The performances of a 120 [kW]−25000 [rpm] solid rotor machine are compared with a caged rotor induction machine for waste heat recovery application.

Over the recent years, there has been a rise in the demand for high speed and high power density machines for various applications in industry ranging from basic household power tools to the flight controls for aircrafts in the aerospace sector. This has also seen advancements in the power electronics and controls for these machines to deal with the large operating frequencies. The increase in demand for high speed machines has been driven by the industry’s requirement for cost reductions, higher robustness & higher efficiencies. This thesis aims to contribute knowledge to the design and development of a high-speed surface mounted permanent magnet machine. A numerical procedure for the detailed sizing of a high-speed surface mounted permanent magnet (SPM) machine is outlined in this dissertation. An analytical per phase model is formulated to examine the performance parameters of the machine. The analytical model is validated against results obtained from Ansys Electromagnetics Finite Element Analysis (FEA) software. The estimation of core losses in high-speed machines is also of critical importance during electromagnetic design. An immense amount of research has been conducted on the estimation of core losses in machines, however, not much has been done to cover the estimation of highspeed core losses as compared to the traditional low-speed machines. As part of the development of the high-speed machine, the numerical estimation of the highspeed core losses was examined and validation performed using FEA software. On average, there was a difference of about 3-11% between the analytical results and FEA results of the eddy current loss and hysteresis loss. These results demonstrate that the analytical method used to estimate core losses is reasonably accurate when compared to FEA results obtained from ANSYS Maxwell. The prototyping of a high-speed surface mounted permanent magnet machine is investigated. Focus is placed on the major components of the machine whilst highlighting the use of precision machining and the need to maintain high accuracy during manufacturing and assembly of the machine prototype.

Control of a low voltage ac/dc/ac converter for high-speed induction machine drive applications has been investigated. Such a configuration can be applied, for example, in microturbines and high-speed spindles. Scalar control is usually applied for the control of high-speed drives especially in the case of very high-speed drives. Indirect rotor-flux-oriented control and direct torque control are designed and compared for the control of an exemplary high-speed induction machine drive. The 2L VSC is the most widely applied converter for high-speed drives. However, the 3L-NPC VSC is an attractive topology if drastically increased switching frequencies are required. A detailed comparison between a 2L VSC and a 3L-NPC VSC as the machine side converter of the exemplary high-speed induction machine drive is carried out. Voltage-oriented control is applied for the control of the grid side PWM active front end converter. In several industrial applications PWM active front end converters commonly operate in parallel to thyristor converter fed dc drives. Behavior of the voltage-oriented controlled active front end converter with L-filter in the presence of a parallel thyristor converter is investigated. The design of the LCL-filter components according to the given maximum grid current harmonics (e.g. IEEE-519) is a complex task. So far a precise and clear design procedure has not been presented. A new procedure to design the grid side filter (L- and LCL-filter) is proposed using the analytical expression of the converter voltage harmonics based on Bessel functions to achieve the compliance with the grid standard of IEEE-519. Voltage-oriented control with active damping is used to control the active front end converter with LCL-filter. A simple method is proposed to design the required lead-lag compensator in the active damping loop.

With the increasingly stringent emissions legislation as well as the hiking fuel prices, engine electrification is currently a prime path for automotive companies to meet the environmental and efficiency targets, thus placing the need for high-performance automotive electrical machines. This research looks at developing high-speed electrical machines for an electrically-assisted turbocharger to be used within Cummins' heavy duty diesel engines. While the potential benefits of such a system are high, integrating a high speed, high power-density electrical machine within the aggressive turbocharger environment is challenging. In this work detailed system multi-domain models which include the electromagnetic, thermal and mechanical aspects are developed. Using these models, together with knowledge of electrical machine material properties, the capabilities and limitations of different types of electrical machines for use in electrically-assisted turbo-charging are determined. The field weakening properties, robustness and relatively low-cost make the Induction Machine the preferred technology for the application. This work provides a set of design guidelines for maximising the power density of high speed Induction Machines. In particular moving away from the conventionally used round rotor-bar and tailoring the split-ratio together with tailoring the machine IS electrical and magnetic loadings are shown to be important aspects in increasing the power density. An algorithm for increasing the power-density of high-speed induction machines is presented. Design recommendations are also presented for PM machines where tailoring the air-gap length is identified and shown to be important in optimising the distribution of losses. A computationally-efficient PEA-based technique is developed for the analysis of closed rotor-slot IMs. The optimized 9.5kW, 50000rpm IM design is prototyped and experimental results compared to those predicted from analysis.

High Speed High Power (HSHP) electrical machines push the limits of electromagnetics, material capabilities and construction techniques. In doing so they are able to match the power performance of high speed turbomachinery such as gas turbines, compressors and expanders. This makes them attractive options for direct coupling to such machinery as either a power source or as a generator; eliminating the need for gearboxes and achieving a smaller system size and greater reliability. The design of HSHP machines is a challenging, iterative process. Mechanical, electromagnetic and thermal constraints are all placed on the machine shape, topology, operating point and materials. The designer must balance all of these constraints to find a workable solution that is mechanically stable, can work within the available electrical supply and will not overheat. This thesis researches the fundamental origins and interaction of the mechanical, electromagnetic and thermal constraints on electrical machines. Particular attention was paid to improving the accuracy of traditional mechanical rotor design processes, and improving loss estimation in inverter fed machines. The issues of selecting an appropriate electric loading for low voltage machines and choosing effective, economic cooling strategies were explored in detail. An analytical iterative design process that combines mechanical, electromagnetic and thermal design is proposed; this process balances the need for speed versus accuracy for the initial design of a machine, with Finite Element Analysis used only for final validation of performance and losses. The design process was tested on the design and manufacture of a 1.1MW 30,000rpm PM dynamometer used in an industrial test stand. The machine operating point was chosen to meet a gap in the industrial machines market and exceed the capabilities of other commercially available machines of the same speed. The resulting machine was successfully tested and comfortably meets the performance criteria used in the design process.

Integration of vehicular ad-hoc network (VANET) and cellular network is a promising architecture for future machine-to-machine applications. This integration helps the vehicles have steady internet connection through cellular network (i.e., LTE), and at same time communicate with other vehicles. However, dead spot areas and unsuccessful handoff processes due to the high speed of vehicles that can disrupt the implementation of this kind of architecture. In this chapter, simplified cluster-based gateway selection (SCGS) scheme for multi-hop relay in VANET network is proposed. The scheme is achieved by utilizing a new routing protocol called an enhanced hybrid wireless mesh protocol (E-HWMP). The simulations results show that SCGS scheme through E-HWMP protocol performed better than ad-hoc on demand distance vector (AODV) routing protocol. Furthermore, SCGS scheme through E-HWMP is compared with other cluster-based gateway selections used in the previous works; the result shows that SCGS scheme through E-HWMP protocol outperforms the other cluster-based gateway selections schemes.
