3-Phase Motor Amperage Calculator

When powering a 3-phase motor, we would want to follow its specifications printed on its motor rating plate. The plate indicates how much power and voltage would run the motor, how efficient it is in translating the input power to output power, and even how much amperage it could allow. If we do not follow these specifications, there is risk of overheating or even burning the motor. We could also end up using the wrong wire sizes when connecting to its power supply.

However, sometimes, the motor rating plate is incomplete or worn off, especially for old and used motors. This is where our 3-phase motor amperage calculator turns out to be especially useful.
