How does a capacitor start motor work?

A motor capacitor, such as a start capacitor or run capacitor (including a dual run capacitor) is an electrical capacitor that alters the current to one or more windings of a single phase AC induction motor to create a rotating magnetic field.

Thereof, how do I check a capacitor?

  1. Choose your tool. Even cheap digital multimeters often have a capacitance setting "–
  2. Shut off the power.
  3. Discharge the capacitor carefully.
  4. Disconnect the capacitor.
  5. Set the multimeter to measure capacitance.
  6. Activate REL mode if present.
  7. Connect the leads to the capacitor's terminals.
  8. Wait for the result.

How do you read a capacitor?

Method 2 Reading Compact Capacitor Codes
  1. Write down the first two digits of the capacitance.
  2. Use the third digit as a zero multiplier.
  3. Work out the capacitance units from context.
  4. Read codes that contain letters instead.
  5. Read the tolerance code on ceramic capacitors.
  6. Read letter-number-letter tolerance values.
