protection
Capacitors are used with motors in two different ways. Sometimes the same motor will have both techniques applied, and be associated with two significantly different-looking capacitors. When motors with brushes are running normally, the motor brushes produce sparks, which cause noise "from DC to daylight". This has nothing to do with PWM -- it ...
Motor capacitor
Motor capacitor. Electrical capacitor used in electric motors. Not to be confused with Punch 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] …

13.9: Single-phase Induction Motors
Permanent-Split Capacitor Motor. One way to solve the single phase problem is to build a 2-phase motor, deriving 2-phase power from single phase. This requires a motor with two windings spaced apart 90 o electrical, fed with two phases of current displaced 90 o in time. This is called a permanent-split capacitor motor in Figure …
What is a Run Capacitor and how does it work?
A run capacitor is designed to continuously regulate the current or phase shift to the windings of a motor or engine with the aim of optimizing its energetic efficiency, and overall performance. On the other hand, start capacitors are not designed for continuous duty, but rather to provide a jolt of built-up energy as required by the system.

How To Reverse The Direction Of A Single Phase AC Motor
To reverse rotation on a single phase capacitor start motor, you will need to reverse the polarity of the starter winding. This will cause the magnetic field to change directions, and the motor will follow. In order to achieve this, you can swap the connections on either end of the winding. Always reverse the wires that lead to the starter winding.
Motor Capacitors
Motor capacitors temporarily store an electrical charge to provide extra torque and improve a motor''s performance and efficiency. Start capacitors deliver extra torque during motor startup, then exit the circuit once the motor reaches operating speed. Run capacitors help the motor maintain a consistent charge while running.
