Abstract :
A three-dimensional finite element analysis (3-D FEA) of disc permanent magnet linear synchronous machine (DPMLSM) along with adequate driver operational strategy selection are presented in this paper. Relations of the machine steady-state performance and the permanent magnet arrangements as well as the excitation winding selections are clearly illustrated. Trade-off between higher PWM operational frequency and driver switching losses are also presented for determining the optimal operational efficiency at any specific output requirement. Based on these investigations, valuable design and operation guidance of a DPMLSM suitable for electric vehicle (EV) applications can be clearly
