摘要：

Thermal analysis of an optimized 3-phase 12/8 switched reluctance motor is presented in this paper. The copper and core losses were constrained during the continuous operation of the motor. The average optimized torque was increased by 11 % compared to the normal model. The single-objective optimization problem was solved in which the conduction angles at four speeds were optimized. The turn on/off angles were selected as -16( 0) and 136 (0) respectively to meet the optimization constraint. At the speed of 1500 rpm, the hotspot on winding first hits the constraint at 128.2 s, while at 15,000 rpm, the temperature on the rotor surface first reaches the constraint at 755 s. It was observed that the temperature constraint on winding is the limiting factor for continuous operation in the low-speed region, and on the rotor surface, it limits the continuous operation in the high-speed region.
