  In this paper, the Hook-Jews (HJ) optimization method is used to optimize a
3-phase Squirrel-Cage Induction Motor (SCIM) as an Electric Vehicle's (EV)
motor. Optimal designs with different numbers of poles, different nominal and
maximum speeds, and different numbers of grooves are compared and the best one
is selected. The optimization method used has advantages such as simple
programming, omission of gradients, short convergence times, and the
possibility of changing individual parameters. Design parameter variations for
optimal designs with rated speeds for 2-pole and 4-pole motors are shown and
explained. The results show that his 2-pole motor with the rectangular stator
and rotor slots and a rated speed of 1800 rpm has the highest efficiency.
