2. Motor capacitor - Wikipedia

   en.wikipedia.org/wiki/Motor_capacitor

   A typical motor start capacitor. 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 ...

3. Ceiling fan - Wikipedia

   en.wikipedia.org/wiki/Ceiling_fan

   A ceiling fan is a fan mounted on the ceiling of a room or space, usually electrically powered, ... Humming can also be caused by a bad start/run capacitor, or a ...

4. Shaded-pole motor - Wikipedia

   en.wikipedia.org/wiki/Shaded-pole_motor

   Even by the standards of shaded pole motors, the power output of these motors is usually very low. Because there is often no explicit starting mechanism, the rotor of a motor operating from a constant frequency mains supply must be very light so that it is capable of reaching running speed within one cycle of the mains frequency.

5. AC motor - Wikipedia

   en.wikipedia.org/wiki/AC_motor

   Schematic of a capacitor start motor. A capacitor start motor is a split-phase induction motor with a starting motor capacitor inserted in series with the startup winding, creating an LC circuit which produces a greater phase shift (and so, a much greater starting torque) than both split-phase and shaded pole motors. This motor has a ...

6. Capacitor - Wikipedia

   en.wikipedia.org/wiki/Capacitor

   Large plastic film capacitors are used extensively in suppression circuits, motor start circuits, and power-factor correction circuits. Ceramic capacitors are generally small, cheap and useful for high frequency applications, although their capacitance varies strongly with voltage and temperature and they age poorly.
