Topology Optimization of Motor Stator to Reduce Vibration

Abstract

This paper provides a topology optimization (TO) of motor stator using an on/off method with considering vibration. The on/off method using evolutionary optimization tends to yield complex shapes, which are impossible to produce in view of engineering. To solve this problem, two methods are introduced: a on/off method with filtering and a normalized Gaussian function network (NGnet) method. Optimization results show that the effectiveness of these methods is confirmed in a TO of an interior permanent magnet motor.
