与正弦电源相比，变速驱动会在电机绕组上产生更高的电 压应力，并有可能形成高频轴电压和轴承电流。因此，必 须依照“ VSD 应用范围 /绝缘材料选择规范”(3GZF 500930-2) 标明电机绕组和轴承绝缘材料以及转换器输出元 件上的滤波器的尺寸，该文件可向 ABB 索取。
在变速传动中，电机 (Pn >30 kW) 必须用屏蔽好的对称电缆 和能提供 360 的电缆密封管(即 EMC 电缆密封管)进行连 接。
在应用变频器时，为了平衡电机机座和驱动机器之间的电 势，电机机座必须采用外部接地。除非这两者都安装在相 同的金属材料基准面上。
机座在 IEC280 以上的电机应采用 0.75 x 70 mm 的带状导线 或至少两根 50mm2 的圆导线。圆导线互相之间的距离至少 为 150mm。

Compared with sinusoidal power supply, variable speed drive will produce higher electrical pressure stress on the motor windings, and may form high frequency shaft voltage and bearing current. Therefore, the dimensions of the motor winding and bearing insulation and the filter on the converter output element must be indicated in accordance with the “VSD Application Scope/Insulation Selection Specification” (3GZF 500930-2), which can be obtained from ABB.
In variable speed drives, the motor (Pn >30 kW) must be connected with a shielded symmetrical cable and a cable seal tube that provides 360 (i.e. an EMC cable seal tube).
In the application of frequency converters, in order to balance the potential between the motor frame and the driving machine, the motor frame must be externally grounded. Unless both are installed on the same metal base level.
Motors with a frame above IEC280 shall use a 0.75 x 70 mm strip lead or at least two 50mm2 round leads. Circular wires should be at least 150mm away from each other.
