Shaded-Pole Single-Phase Motors

We know that single phase induction motors are not self-starting. Inorder to make single phase motor a self-starting one, a certain arrangement must be provided so that the stator flux produced becomes a rotating one rather than alternating one.Such an arrangement is provided by shaded pole motors.

Speed Control of Slip Ring Motors

A slip ring motor or a phase wound motor is an induction motor which can be started with full line voltage, applied across its stator terminals. The value of starting current is adjusted by adding up external resistance to its rotor circuit. Read here to find out how the speed control is achieved

How Does A Slip Ring Motor Start?

The slip ring induction motor has two distinctly separate parts, one is the stator and other is the rotor. The stator circuit is rated as same in the squirrel cage motor, but the rotor is rated in frame voltage or short circuit current
