Tips: Summarize some important information of the impact on cable size of a motor
1) Always check the wiring to match the load profile - see motor nameplate data.
2) All motors are not created equal. If the motor is not rated for use with VFD, it is certain to fail quickly and dramatically, either by failure of insulation (and arc to chassis / ground) or by bearing failure due to circulating currents. So if it is not rated for VFD, don't use it with a VFD.
3) All cables are not created equal. VFDs produce voltage spikes in the order of 1600-2000V while artificially generating the desired sine wave that drives the motor. This is 2-4x the rating of most electrical wire insulation. If the wire is not rated for this voltage, it will quickly fail, allowing the voltage to ACR to nearest conductor (or personnel) with dangerous or deadly results.

Great Value, Does the Job

I’m really happy with this VFD. It’s a solid product at a great price. The V/F control is effective, and the torque boost feature helps the motor start smoothly. I’ve been able to adjust the motor speed to fit various tasks without any issues.
