The AC single-phase induction motor that has been around the longest is the shaded-pole motor. The auxiliary winding of a tiny squirrel-cage motor with shaded poles is made up of a copper ring or bar that encircles a piece of each pole.
Motor with Shaded Poles used in table fans as well as exhaust fans and hair dryers. used in cooling fans, refrigeration equipment, and air conditioning systems. projectors, photocopiers, record players, and tape recorders. used to start synchronous timing motors and electronic clocks in one phase.
The shaded pole induction motor is made in a fairly straightforward manner. In shaded pole motors, it is impossible to reverse the direction of rotation.
GLOBAL SHADED POLE MOTOR MARKET SIZE AND FORECAST
The Global Shaded Pole Motor market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
With a delay of magnetic flux via the pole structure, this motor creates a spinning field. A copper conductor that forms a single turn around the pole is used to connect the rest of the pole to the shaded area of the pole. The magnetic flux in the area of the winding that is not shaded increases as the current does.
Due to the current created in the copper, this causes a delay in the magnetic flux of the shaded area. This motor has a relatively small torque, typically less than 1/4 HP. A rotor with high resistance is utilised to increase the torque.Because of this motor’s extremely low efficiency and use in applications that only require brief operation.
The shaded pole motor’s low cost makes it suitable for use in small devices like relays, fans, and other electronics. Table fans, cooling fans, refrigerators, air conditioners, projectors, hairdryers, exhaust fans, and more
Flux is induced in the primary region of the pole when power is applied to the stator. In the shade coil, this flux induces a voltage. A secondary winding is created by this. Lenz’s law states that the current direction should be such that it opposes the flux entering the coil. In a transformer, this serves as the secondary winding.
