摘要
施力状态工作之音圈电机,为求得其精度的提高,力求减少漏磁通。本文就磁钢轴向二侧附加钢质磁屏蔽环之音圈电机进行磁场数值计算,结果表明选择合适的屏蔽环厚度,达到了削弱漏磁通的目的。
In the state of application of force, in order to increase the precision and to reduce the leak-flux of voice coil motor, numerical value calculation of magnetic field of the voice-coil motor with added steel ring shielding magnetism on two sides of magnet steel was carried out in this paper. The result shows, leak-flux would be weakened by selecting suitable thickness of the ring shielding magnetism.
