Portable record players typically used an inexpensive shaded-pole motor.

Also, single-phase shaded-pole motors have a fixed rotation, and the direction cannot be changed.

Shaded-pole motors with an asymmetric mechanical construction which is simple, robust and maintenance free.

A reversible shaded-pole motor was made by Barber-Colman several decades ago.

Shaded-pole motors are the original type of AC single-phase induction motor.

The Original employed a shaded-pole motor from its inception until 1984, at which point it was changed to a permanent split-capacitor motor.

A shaded-pole motor has a winding around part of the pole that delays the phase of the magnetic field for that pole.

Compared to AC fans using shaded-pole motors, they are very efficient, running much cooler than the equivalent AC motors.

A common single-phase motor is the shaded-pole motor and is used in devices requiring low starting torque, such as electric fans, small pumps, or small household appliances.

Squirrel-cage induction motor: The most common type of shaded-pole motor in fractional horsepower use is the squirrel-cage induction motor.

A shaded-pole motor is basically a small squirrel-cage motor in which the auxiliary winding is composed of a copper ring or bar surrounding a portion of each pole.

The stator core looks a lot like one in a shaded-pole motor, and it defines the rotational direction according to the position of holes, grooves, or shade windings through the stator.

The invention of the shaded-pole motor allowed self-starting clocks to be made, but since the clock would restart after a power interruption, the loss of time would not be indicated.

Multiply these values times each other and times power factor, which for shaded-pole motors is about 0.6 and for permanent-split-capacitor motors is about 0.9.Read the rated amperage and voltage off the motor nameplates.

Shaded-pole motors of the asymmetrical type shown are only reversible via disassembly and flipping over the stator, though some similar-looking motors have small, switch-shortable auxiliary windings of thin wire instead of thick copper bars and can reverse electrically.

However, unlike a shaded-pole motor, the grooves are at backward positions, and the positions where the rotor settles after each cycle are well determined, which is not the case for induction motors in general, where slip and load affect the angle that the rotor turns each cycle.
