Use a single-phase permanent-split-capacitor type AC motor and wire its lead wires directly to a single-phase power supply (skip the capacitor). The motor most likely won''t run with the load unless the shaft is rotated by an external force (this is much easier with an ungeared, round-shaft motor).
Construction of Single-Phase Induction Motor. A single phase induction motor is similar to the three phase squirrel cage induction motor except there is single phase two windings (instead of one three phase winding in 3-phase motors) mounted on the stator and the cage winding rotor is placed inside the stator which freely rotates with …

Improve motor performance by ensuring even rotation in single-phase, continuously running AC motors, such as those in air conditioning units. Oval Capacitors Housing
A single-phase induction motor is a small-size motor with a fractional-kilowatt rating. They work on the principle of electromagnetic induction to create a rotating magnetic field. It is used in domestic appliances like fans, hair dryers, washing machines, vacuum cleaners, mixers, refrigerators, food processors and kitchen equipment employ …
Many single-phase compressors require a start capacitor to assist in starting the motor. These capacitors will occasionally fail, causing a compressor to fail to start. Overheating is a primary cause of a failed start capacitor. Start capacitors are not designed to dissipate the heat associated with continuous operation; they are designed …
The capacitor start single phase induction motor is a type of split-phase induction motor. Capacitors are used to improve the starting and running performance of the single-phase inductions motors. The capacitor start motor is identical to a split-phase motor except that the starting winding has as many turns as the main winding.

Run Capacitor Selection Guide. A run capacitor is used to continuously adjust current or phase shift to a motor''s windings in an effort to optimise the motor''s torque and efficiency performance. Because it is designed for continuous duty, it has a much lower failure rate than a start capacitor. Index. Overview
In addition to the power supply and windings, a 120 volt single phase motor may also have a capacitor. The capacitor is used to improve the motor''s starting torque and power factor. The capacitor will have two wires – a positive wire and a negative wire – which will be connected to specific terminals on the motor. ...
