XYCOM XVME-530

XYCOM XVME-530如果需要变速，可以使用变频驱动 (VFD)，但在 “标准” 电机中添加变频驱动功能时，可能会出现绝缘应力、EMI 和共模电流流过电机本体等问题。

对于直流或通用交流转直流电源，电机旋转时，其电刷通过依次给线圈通电来强制换向和旋转。这些电机成本低，性能优，启动转矩大，因此在小型工具和电器中很受欢迎。

然而，电刷确实会磨损，而且通常产生高压电弧和可听噪音。通过改变直流或交流电源电压，或通过交流相位角控制来实现具有可选闭环调节的速度控制，这些通常效率较差，但为励磁线圈分接开关提供了可能。

目前常用的电机类型是无刷直流电机 (BLDC)，是基于有刷直流电机改进而来，可以去除电刷。

此类电机的性能，效率更高，寿命更长。
