If you choose Start capacitor it has to be in a circuit that disconnects the capacitor after start otherwise the motor will suffer. Per your schematic you do have the Centrifugal switch (Cent SW) to turn off the start capacitor. You are all set, so get a capacitor. Start capacitors are usual 50uF or larger. The run capacitors are 5uF range.
"Capacitor-run" also uses a second capacitor to increase power factor and improve efficiency. If you remove a start capacitor you would have to manually spin the motor in order to develop torque to get it up to speed. If you remove the run capacitor the motor is gonna be a lot less efficient at speed, and under heavy load you risk overheating.
Motor start and motor run capacitors Start capacitors. Motor start capacitors are used during the motor startup phase and are disconnected from the circuit once the rotor reaches a predetermined speed, which is usually about 75% of the maximum speed for that motor type. These capacitors usually have capacitance values of over 70 µF.
It could be caused by a broken or loose connection, a faulty capacitor, or a faulty motor winding. Additionally, the motor may not be receiving sufficient power due to a malfunctioning electrical panel or circuit breaker. When an electric motor doesn''t receive adequate power, it will attempt to turn, causing a humming sound.
