Motor torque, load torque and selection of motors

Motor torque, load torque and selection of motors 2/45 Performance In such motors the pull-out torque is normally less than the starting torque. This is because the pull-out torques by the two cages occur at different speeds. Such motors would possess a low power factor and efficiency compared to an ordinary squirrel cage motor, because of the high

What is the role of the power factor in motors? - Quora

Answer (1 of 3): Power P=VI*powerfactor. It is the angle between voltage and current. So when power factor is unity.I.e 1, there is no loss of power. But practically most loads are inductive in nature hence there is a lag in power factor i.e.not unity and hence power will not be good. It is a ...
