Optimal designelectrical vehicleinduction motor,
In this paper a squirrel-cage three-phase induction motor, selected as the driving power of an EV, is designed optimally using Modified-Hooke-Jeeves optimization technique. The optimal designs are analyzed and compared with varying pole number, rated base speed and slot shapes. This optimization technique has same advantages such as simple programming, non-gradient, short convergence time and independently variation of each parameter. Variation of design parameters of optimally designed motors versus rated base speed for 2 and 4-pole motors are presented and discussed. The results show that a 2-pole motor with parallel-sided stator and rotor slots and rated speed 1800 rpm have the best performance
