摘要：

The cogging torque and dynamic performance of a newly designed single phase brushless DC motor have been investigated in this paper. The single phase brushless spindle motor is usually applied for cooling fan, pump and blower before the performance is improved by the reengineering process. The stator configuration and the drive circuit have been remodeled in order to meet the requirements of the spindle motor used in the DVD and HDD applications. The cogging torque is reduced to 18 g-cm by the salient pole An automatic phase adjuster is also introduced to improve the performance of the dynamic characteristics of a single phase spindle motor in this paper. According to the test results, the maximum speed could be increased from 6500 rpm to 12000 rpm and the efficiency from 22% to 38%. A single phase motor has been demonstrated successfully used in the HDD and DVD application by reshaping for the salient pole and phase adjusted automatically with the rotation speed in this paper.
