Dec 01 1995 Single phase motors also have a rotating magnetic field. The rotating field required to start the motor is generated from a second winding called a starting winding. After the motor is up to speed the starting winding is disconnected and the rotating field is developed by interaction of the stator main winding and the rotor.

Feb 24 2012 Starting torque is the torque produced by induction motor when it starts. We know that at the start the rotor speed N is zero. So the equation of starting torque is easily obtained by simply putting the value of s = 1 in the equation of torque of the three phase induction motor The starting torque is also known as standstill torque.

Mar 26 2022 The heart of any electric motor consists of a rotor that revolves around a stationary part called a stator. The stator traditionally made of iron tends to be heavy. Stator iron accounts for about two thirds of the weight of a conventional motor. To lighten the stator some people proposed making it out of a printed circuit board. Although the idea of replacing a
When higher than standard pull out torque is required 80 leading power factor motors should be considered. The easiest way to design for high pull out is to provide additional flux which effectively results in a larger machine and allows a leading power factor. The leading power factor motor may therefore be less expensive overall.
