This paper presents the performance investigation and design technology of Line Start-up Permanent Magnet Synchronous Motor(LSPMSM) with super premium efficiency, including design consideration and evaluation for motor starting-up, key performance, advanced finite element analysis(FEA) for the design, improvement and verification, prototype build and test, design and test data comparison to Premium® Efficient Induction Motor(PEIM). To assess the design technology, LSPMSM prototype was built amended from a PEIM with the same frame, stator punching and rated output. Based on the prototype test, two novel improvement designs and analyses have been done to eliminate the noise and vibration. Additionally, the comparisons with PEIM on power factor, efficiency, frame size and active material consumption indicated the significant performance improvement and active material cost down can be achieved by LSPMSM.

This paper presents a direct torque control technique for brushless DC motors with non-sinusoidal back electromotive force. Direct torque control has some benefits such as faster torque response and reduced torque ripple for driving the brushless DC motors. Because of ignoring stator flux linkage of direct torque control in constant torque region, driving of brushless DC motors is not complicated. In order to solve the problems associated with conventional PI speed controller, a new speed control based on adaptive-neuro fuzzy inference system is proposed to eliminate overshoot in the torque and speed responses, simplify designing and reduce complexity of math formulas. To reduce rising time, PD controller is used with adaptive-neuro-based Fuzzy Inference System. The effectiveness of proposed system has been validated by simulation results.

The paper presents a comparative study of 3-phase permanent-magnet (PM) synchronous machines (PMSM) with concentrated windings. The purpose of this study is to find a machine giving the better electromagnetic performance (torque, losses, back electromotive force…) for railway traction. Three PMSM with concentrated windings having identical output power, stator and rotor outer diameter, air-gap, axial length,…, are designed. Two machines have equal tooth widths, with one having a coil wound on every tooth and the other having a coil wound on alternate teeth, while the third machine has also coils wound on alternate teeth but these are wider than the unwound teeth. A comparison of the performances for single layer and double layer concentrated windings is made using finite element analysis.

Base on 3D finite element method a 3D electromagnetic model for a three-phase three-limb power transformer is given and analyzed. Such a model can give not only the correct load losses in windings, but also the satisfied stray losses with measured in the transformer tank. Influences of magnetic shunts on tank losses are discussed. Simulation indicates that the magnetic fields on tank wall are decreased by the covered magnetic shunts, but magnetic fields on tank wall nearest to the abrupt angles or edges of magnetic shunt plates are increased and are stronger than the other parts. Filleting the shunt plates angles or edges may decrease the fields on tank wall.

This paper presents a 3D Magnetic Equivalent Circuit modeling of a homopolar Hybrid Excitation Synchronous Machine with distributed windings and interiors permanent magnets. The MEC model is based in a 3D reluctance element. Movement and saturation effect are taken into account. The average torque is estimated by two methods: Flux-FMM and Maxwell Stress Tensor methods. Results from the MEC model are compared to corresponding FEA computations.

Equivalent circuit model of induction motors was established and the formulas of power losses were given. Motor efficiency was optimized by Genetic Algorithm(GA) and Hybrid Genetic Algorithm(HGA). Power factor, breakdown torque ratio, locked-rotor torque ratio and locked-rotor current ratio were regarded as constraints and the optimal result is satisfying. Genetic Algorithm and Pattern Search Algorithm are integrated into a composite algorithm-Hybrid Genetic Algorithm. Motor efficiency rises further through Hybrid Genetic Algorithm.

Predictive direct torque control (PDTC) has been proposed and well developed because of its excellent steady-state and transient performance. On the other hand, due to the elimination of proportional-integral regulator, direct virtual torque control was presented and proved to be an effective method for doubly fed induction generator (DFIG) grid synchronization. This paper proposes a novel DFIG grid synchronization strategy combining the merits of PDTC and virtual torque concept. The control system is very simple and robust while the smooth and fast grid synchronization is achieved.

This paper investigates factors influencing coupling ability of ironless flat winding separable transformer which could work for the contactless power supply system of the high speed maglev train. Basing on 3D finite element method (FEM), the coupling ability to geometrical sizes such as coil length and width, height of air gap and the horizontal displacement of the secondary coils is given. Effect of high frequency on the contactless power supply system is also taken into consideration. The work of this paper provides foundation for the optimized design of high coupling ability ironless flat winding separable transformer.

Doubly salient machine with a rectifier circuit constitutes a type of simple BLDC generators, which include doubly salient permanent magnet generator (DSPG), doubly salient electro-magnetic generator (DSEG) and doubly salient hybrid excitation generator (DSHEG). Magnetic field analysis of these generators is carried out based on finite element method (FEM). Hence, a comprehensive comparison of the static characteristics of these three kinds of generators is investigated. The output characteristics of these generators are compared by field-circuit coupled analysis. Results of comparing the three generators such as the voltage regulation, total mass of effective materials, the maximum power, power density and the efficiency are given.
