Application

Fan, also known as ventilating machine, is a kind of motor (or rotary machinery) that uses a rotating impeller to convert electrical energy (or mechanical energy) into gas potential energy and kinetic energy, which is used to transport air and its mixture of power machinery and maintain the continuous flow of air or other gases.

Like any other motors the shaded pole induction motor also consists of a stator and rotor. The stator is of salient pole type and the rotor is of squirrel cage type. The poles of shaded pole induction motor consist of slots, which are cut across the laminations. The smaller part of the slotted pole is short-circuited with the help of a coil. The coils are made up of copper and it is highly inductive in nature. This coil is known as shading coil. The part of the pole which has the coil is called the shaded part and the other part of the pole is called unshaded part.

An alternating current is passed through the excited winding which surrounds the pole. Due to the presence of shading coil, the axis of the pole shift from unshaded part to shaded part. This shifting effect is equivalent to the physical movement of the poles, which is nothing but the rotation of poles. So the rotor starts rotating in the direction of the shift from unshaded part to shaded part.

During the positive half cycle of the alternating current, North Pole shifts from unshaded part to shaded part and during the negative half cycle, the South Pole shifts along from unshaded part to shaded part. This effect is nothing but the rotation of poles from left to right.

Shaded coils aids in producing the rotating flux and thus the single phase Induction motor is converted into self starting one using the Shading coil. Due to fixed of position of shading coils, the direction of rotation of such motors cannot be changed.

Advantages and Applications

The various advantages of Shaded pole motors includes:

• Very cheap and reliable
• Easy to construct
• Extremely rugged in nature

Uses:

• Due to their low starting torques they are mostly employed in small instruments, toys, small fans, electric clocks, hair dryers, ventilators, circulators etc.
