Aug 30, 2021· The maximum torque of the induction motor is independent of the rotor resistance. The greater the value of rotor resistance R 2 , greater is the value of slip at which maximum torque occurs. When the rotor resistance is increased, the pull-out speed of the motor decreases, but the value of maximum torque remains constant.

Rotor – The shaded pole motor uses the squirrel cage rotor. The bars of the rotor are skewed at an angle of 60º. The skew can be done for obtaining a better starting torque. The construction of the motor is very simple because it does not contain any commutator, brushes, collector rings, etc., or any other part.

Oct 05, 2020· Single-Phase Induction Motor Design. The two main components of the single-phase induction motor are the stator and rotor. As you may know and perceive from the name, the Stator is the stationary part of this motor. On the other hand, the rotor is the rotating component of the motor. the single-phase alternating supply reaches to the stator,
