What type of winding is made use of small motors?

Small motors, particularly those found in household appliances, toys, and other low-power applications, typically use one of the following types of windings:

1. Single-phase windings: These are common in very small motors where simplicity and cost are key factors. Despite their simplicity, single-phase motors can suffer from starting and efficiency issues.

2. Shaded-pole windings: Frequently used in the smallest AC motors, shaded-pole motors have a very simple construction with a single coil winding. They’re inexpensive, reliable, but not very efficient or powerful, making them suitable for low-power applications, such as fans or small pumps.

3. Split-phase windings: These are used to improve the starting torque of single-phase motors. They utilize an additional starting winding that is out of phase with the main winding to produce a rotating magnetic field, which helps the motor start more reliably. After starting, the starting winding is disconnected by a centrifugal switch or an external control.

4. Permanent Magnet DC (PMDC) windings: In small DC motors, permanent magnets are used for the stator, and the rotor is wound with an armature winding. These motors are efficient, have good torque characteristics, and are easy to control speed-wise, making them suitable for battery-powered devices, electric toys, and portable electronic devices.

5. Universal Motor Windings: These motors can operate on either AC or DC supply and typically have series windings. Universal motors are known for their
