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 https://casadepalomas.com

Web1 : a force that produces or tends to produce rotation or torsion (an automobile engine delivers torque to the drive shaft); also : a measure of the effectiveness of such a force that consists of the product of the force and the perpendicular distance from the line of action of the force to the axis of rotation 2 : a turning or twisting force WebTo achieve this a simple method is to vary both voltage and frequency so that V/f is constant. The torque-speed curves with constant V/f are depicted in Fig. 1.31. There is a depletion of torque at low frequencies. The motor has reduced torque capability and overload capacity.
