WebTorque Production in Induction Motor. In this article we begin with a brief description of rotor types, and introduce the notion of ‘slip’, before moving onto explore how the torque is produced, and investigate the variation of torque with speed. We will find that the behaviour of the rotor varies widely according to the slip, and we ... WebTorque vs. slip speed is only constant if the applied voltage is proportional to the applied frequency. Maximum torque is approximately proportional to the square of the voltage/frequency ratio. If that ratio is too high, the stator iron will be magnetically saturated. If the ratio is too low, the torque may not be sufficient tor drive the load. fredericksburg water heater repair

If slip increases, operating speed falls into breakdown region, where motor pullout draws high current. ... Like setting 6, the V/Hz is high at minimum speed to provide high motor starting torque. The curve quickly drops, and remains relatively flat until ~50% speed. WebThe torque is the twisting force that makes the motor running and the torque is active from 0%to 100%operating speed. The power produced by the motor depends on the speed of the motor and is zeroat 0%speed, … blind fist of bruce 1979
