This paper proposes a nonlinear equivalent magnetic network (EMN) model of a transverse-flux permanent magnet linear motor (TFPMLM) to obtain the performances quickly. The meshing method is employed to solve magnetic fields in air gap, magnet, and iron. The air gap flux density distribution is solved by EMN model, based on which, the EMF waveform, no-load cogging force waveform and load force waveform are obtained. Finally, the prototyped TLPMLM is manufactured and the modeling results are compared to the experiment and 3D FEM, respectively. An important computing time is won with an acceptable accuracy.

The analysis of the performance of various structural solutions of the cooling system for the in wheel car motor is presented in the work. The analysis was conducted on the prepared spatial calculation models using the CFD software. The maximum motor temperature for various solutions of the stator support structure and for different shapes of the water jacket channel was determined as a result of simulation. The analysis for a steady state with constant losses corresponding to the S1 motor operation point and the constant flow of the cooling medium was carried out. The calculations were made by building separate discrete models for each analyzed case. The information how the structural changes affect the efficiency of the cooling system and how to improve the prototype of the in wheel car motor was given as a result of conducted thermal simulations.

Transverse- flux machines (TFMs) optimised to have a high torque density and a satisfactory power factor remain candidates for direct drive generators for high torque, low speed tidal and wind turbines. However, due to their complex structure their design tends to rely heavily on time consuming 3D fininte element analysis (FEA). In this paper we derive and present a set of normalised curves relating particular TFM's performance indicators to its normalised dimensions; the theory can be used to obtain similar curves for other TFMs. Additionally, the paper presents a design methodology using these curves to quickly determine the near optimal proportions of the machine, and estimate its performance. This will help to reduce the FEA effort considerably: FEA can be reserved to the final design stage, to refine and verify the design. The methodology is applied to the design of two machines for a commercial direct drive tidal generator that was developed at the University of Southampton.

A continuous demand for more efficient and more compact drives is pushing the popularity of high-speed permanent-magnet synchronous machines. However, high rotational speeds and extreme power densities imply that an appropriate cooling of the rotor may be difficult. This is all the more important because of the risk of demagnetization when permanent magnets are operated at high temperatures. Therefore, it is paramount to reduce the losses in the rotor of highspeed machines as much as possible. One technique to reduce the eddy-current losses is introducing a shielding cylinder, i.e. a conductive sleeve that is wrapped around the magnets. However, when badly designed, such a shielding cylinder may increase, rather than decrease, the losses. Therefore, an in-depth study of the effect of the shielding cylinder on the eddy-current losses in high-speed PMSMs is required. By studying how the eddy-current losses are affected by the shielding cylinder's thickness and its conductivity, this work aims at providing more insight in how the eddy-current losses can be reduced.

Online condition monitoring and fault diagnosis systems are necessary to prevent unexpected downtimes in critical electric powertrains. The machine learning algorithms provide a better way to diagnose faults in complex cases, such as mixed faults and/or in variable speed conditions. Most of studies focus on training phases of the machine learning algorithms, but the development of the trained machine learning algorithms for an online diagnosis system is not detailed. In this study, a complete procedure of training and implementation of an online fault diagnosis system is presented and discussed. Aspects of the development of an online fault diagnosis based on machine learning algorithms are introduced. A developed fault diagnosis system based on the presented procedure is implemented on an in-house test setup and the reliably detected results suggest that such a system can be widely used to predict multiple faults in the power drivetrains under variable speeds online.

In this paper a scaling methodology for the solution of 2D FE models of electric machines is proposed. This allows a geometrical and rotor resistance scaling of a squirrel cage induction machine enabling an efficient numerical optimization. The 2D FEM solutions of a reference machine are calculated by a model based hybrid numeric induction machine simulation approach. In contrast to already known scaling procedures for synchronous machines the FEM solutions of the induction machine are scaled in the stator-current-rotor-frequency-map and then transformed into the torque-speed-map. This gives the possibility to use a new time-scaling factor, that is necessary to keep a constant field distribution. The scaling procedure is validated by the finite-element-method and used in a numerical optimization process for the sizing of an electric vehicle traction drive considering the gear ratio. The results show that the scaling procedure is very accurate, computational very efficient and suitable for the use in machine design optimization.

This paper presents the finite element analysis of a multiphase permanent-magnet motor designed to have independent phases structure according to the principles of fault tolerance. The goal of the study is to verify and quantify the independence of the phases from the electromagnetic point of view, one of the key requirements of fault-tolerant machines. The case study refers to a five-phase permanent-magnet motor designed for an aircraft flap application. The typical operating conditions of motors designed to operate in fault tolerant environments are considered, such as the opening of one or more phases after the occurrence of a failure. The actual performance of the multiphase motor is compared to that achieved by the superposition of the effects of each phase fed independently, which is the straightforward approach in usual modeling. The results demonstrate that modeling by independent phases leads to negligible errors in almost all the operating conditions.

The damper windings of salient-pole, wound-field synchronous generators are currently attracting a renewed interest due to their impact on the machine efficiency and power quality, which was somewhat overlooked in the past. This paper focuses on the equivalent circuital modeling of damper windings. After recalling its main physical features, the general approach is first presented, permitting to define an equivalent circuit and to derive the related resistance and inductance matrixes whatever is the pattern of the cage bars. Further assumptions deriving from common or advanced features of damper windings are then analyzed, such as symmetrical, antisymmetrical, shifted and modulated position patterns. It is then shown how such assumptions can be exploited to simplify and shrink the equivalent circuital model of damper windings when analyzing realistic operating conditions.

In this paper, we investigate rotor design of claw pole alternators for automobile applications from the observations of detailed 3D flux paths in rotors. First, the electromagnetic field distribution is calculated by 3D nonlinear time-stepping finite element method that considers eddy currents generated at solid rotor core and laminated stator core. From the results, a novel rotor design is proposed to increase output of the alternator. Experimental verification is carried out to confirm the advantage of the proposed design. The mechanism of output increase by the proposed alternator is revealed by analyzing detailed 3D flux paths in the rotors.

Increasing renewable energy integration to grid requires inertial support to improve frequency stability of the power system. Inertial support of renewable energy systems requires hardware verification in order to test practical limitations and absence of dynamical grid simulators makes verification studies more challenging. In this study, a test rig which is composed of a DC motor, an AC synchronous generator and an external flywheel, is developed in order to provide a platform in which dynamic properties of an actual power plant can be simulated in the laboratory conditions. A 4 kVA power plant simulator with a field exciter and a speed governor is developed with 1kVA buck converters. The frequency response of the test bench is controlled in parallel with the computer simulations in Digsilent Powerfactory environment. The developed test rig is a low cost and simple solution aimed for experimental studies regarding inertial support of renewable energy systems or power system frequency studies.
