Another variation is the permanent-split capacitor (or PSC) motor. [25] Also known as a capacitor-run motor, this type of motor uses a non-polarized capacitor with a high voltage rating to generate an electrical phase shift between the run and start windings.
A motor capacitor [1] [2] is an electrical capacitor that alters the current to one or more windings of a single-phase alternating-current induction motor to create a rotating magnetic field. [ citation needed ] There are two common types of motor capacitors, start capacitor and run capacitor (including a dual run capacitor ).
Alternatively, certain manufacturers employ custom-wound Permanent Split Capacitor (PSC) motors with speed taps in the windings. These taps are set to the desired speed levels for the specific design of the fan coil unit. To enable local control, a simple speed selector switch (Off-High-Medium-Low) is provided for the occupants of the room.

The Hunter Original employed a shaded-pole motor from its inception until 1984 (the 91.44 cm Original remained shaded pole before it was replaced with the 106.68 cm Original in 1985), at which point it was changed to a much more efficient permanent split-capacitor motor.
A variation of the centrifugal switch used a changeover contact to ensure that the auxiliary windings remain in the circuit through a running capacitor. These motors are called two-value or capacitor start capacitor run motors. Centrifugal switches are found in many clothes dryers, supplying power to the motor in parallel with the start switch ...

In electrical engineering, electric machine is a general term for machines using electromagnetic forces, such as electric motors, electric generators, and others.They are electromechanical energy converters: an electric motor converts electricity to mechanical power while an electric generator converts mechanical power to electricity.
