How Does the Shaded Pole Motor Operate?

The shaded pole motor operates using a simple design that relies on electromagnetic principles. It consists of a stator with shaded poles and a rotor. The stator generates a rotating magnetic field when an alternating current flows through the windings.

First, the shaded pole creates a delay in magnetic flux in one part of the pole. This occurs because of a copper shading coil that surrounds part of the pole, resulting in varying magnetic strength. This difference causes the rotor to turn in the direction of the strongest magnetic field.

Next, the rotor, which is typically a squirrel cage design, spins as the magnetic field advances. The interaction between the rotating magnetic field and the rotor induces currents in the rotor bars. This inductive effect generates torque, causing the rotor to accelerate.

Finally, the rotor continues to spin as long as the alternating current is supplied. The design of the shaded pole motor allows it to run smoothly and efficiently at low speeds.

In summary, the shaded pole motor functions through the interaction between a rotating magnetic field and the rotor, driven by the phase difference created by the shading coil.
