Do you know how to calculate the current of a three-phase motor? And how to calculate the power of a three-phase motor? In this video, I will show you how easy it is to find out the nominal current of a three-phase motor, and easily calculate the thermal relay, contactor and cable for a three-phase motor. After all, to know how to calculate the cable for a three-phase motor, or to know how to calculate the thermal relay and contactor for a three-phase motor, you need to find out the nominal current of the motor. And in this video, I will show you the easiest way, including how to read the nameplate of a three-phase motor. Three-phase motors at 220v or 380v, with star or delta closure, are the same calculations demonstrated in this video.
