Description

This is a model of an industrial AC electric motor with squirrel cage rotor. The motor is not controlled by a power electric convertor. Instead its performance is directly defined by a torque speed curve.

ACMotorCharacteristic

The torque speed curve is fully defined by the parameters shown in the picture. The synchronous speed is defined as:

 

n = 2 * voltage frequency / no. of poles
