Shaded pole single-phase induction motors are used in applications such as _____.

The correct answer is option 4):(electric clocks)

Concept:

• A shaded pole induction motor is a type of self-starting 1-phase induction motor. It consists of a stator and a squirrel cage type rotor. The stator of the shaded pole motor is made up of salient poles and each pole is slotted on a side and a copper ring is fitted on the smaller part of the slot
• In a shaded pole induction motor, a shaded coil will produce a very weak rotating magnetic field and also not at constant magnitude.
• Therefore these are small ratings starting from 20 watts.
• This motor can be used for toys, hair dryers, desk fans, cooling fans, electric clocks, slide projectors, advertising displays, Air conditioners etc
