Abstract

The cogging torque in the small brushless DC (BLDC) motors used in the digital versatile disk (DVD) driving system or hard disk drive (HDD) system can cause some serious vibration problems. In this paper, some core shapes that reduce cogging torque are found by using a reluctance network method (RNM) for magnetic field analysis and a genetic algorithm (GA) for optimization. The outer rotor type BLDC motor for the DVD ROM driving system has been optimized as an sample model.
