In this paper, the basic design of linear synchronous motor(LSM) for high speed propulsion system is performed. By characteristics analysis of designed LSM, peak to peak magnitude of thrust force ripple is almost 88% of total thrust force. Because of this reason, designed LSM required an application of module phase set shift(MPSS) in order to reduce the thrust force ripple. Using design of experiments, Taguchi method, and approximate design, sub optimal design is established.

This paper presents maximum power control of IPMSM for EV/HEV. Conventional maximum power control of IPMSM approximated the stator resistance. This common assumption was allowed to high-voltage and low-current type motor. But, since IPMSM for EV/HEV have low voltage source and large current capacity, the lack of control voltage is caused by the assumption of stator resistance. And it makes nonlinear characteristics of the motor control, especially overmodulation in PWM inverter. So it needs to consider voltage drop between the stator resistance. In this paper, voltage equation including the stator resistance was used for the maximum power control of IPMSM. For solving complexities of this equation, Newton method was used. Finally, the proposed method was verified to compare with the conventional method by matlab/simulink simulation results.

The interior permanent magnet synchronous motor (IPMSM) with its robust rotor construction, using reluctance torque and flux weakening capability is suitable for hybrid electric vehicle (HEV) application where wide speed and torque range is required. Characteristic of permanent magnet is depend on temperature, so flux of motor is varied and torque is also changed according to temperature. This paper presents the novel current compensation algorithm of IPMSM for HEV. To reduce effect of temperature in IPMSM, command current is selected using current map which is obtained by linear interpolation. The datum point is selected at 20, 80, 100 and 150 degrees. We make simulation and experiment to confirm current controllability.

This paper presents design process of linear induction motor in dynamic tester for catenary-current collection. To minimize length of rail for dynamic tester for catenary-current collection, accelerating performance of the linear induction motor is very important. So the design process of linear induction motor considered in this paper is different with general design process of linear induction motor, because dynamic tester has three type driving region, as accelerating region, constant speed region, and braking region. Considering accelerating performance of motor, distance and time from starting point to constant speed region were concerned for load condition of motor. Designed linear induction motor was analyzed by 2-dimensional finite element method. Using mechanical dynamics simulation with analysis result of 2-dimensional finite element method, accelerating performance of designed motor was proved.
