Capacitor Motor. A capacitor motor is a single-phase induction motor with a main winding arranged for a direct connection to a source of power and an auxiliary winding connected in series with a capacitor.

What Does A Motor Capacitor Do? Single-phase motors use capacitors to help get them started and for energy saving. There are two main kinds of motor capacitors: 1. Start Capacitors. 2. Run Capacitors. Now that you know the two main types of motor capacitors, let''s talk about what each kind of capacitor does and how it affects your motor. Start
Start capacitors increase motor starting torque and allow a motor to be cycled on and off rapidly. Start capacitors are designed for momentary use. Start capacitors stay energized long enough to rapidly bring the motor to 3/4 of full speed and are then taken out of the circuit.
Motors primarily use vapor deposition electrode capacitors as specified in JIS C 4908 Capacitors for Electrical Equipment. This type of capacitor is also commonly referred to as a SH (Self Healing) capacitor because a metal-deposited plastic film is used for its components, which has a self-healing effect.

Capacitor motor with a speed limiting governor device. Start capacitors lag the voltage to the rotor windings creating a phase shift between field windings and rotor windings. Without the start capacitor, the north and south magnetic fields will line up and the motor hums and will only start spinning when phsically turned, creating a phase shift.
The physical construction of a capacitor-motor can be done by connecting a capacitor unit near the motor. The shape of the capacitor-motor is a cylindrical hump.
There are three types of capacitor motor which include the following. Start capacitors are very helpful in enhancing the starting torque of a motor & allow a motor to be On & OFF quickly.
Capacitance Value: Make sure the capacitance matches your motor’s requirements. A start capacitor, for example, needs a much higher capacitance than a run capacitor. Voltage Rating: To avoid potential failures, always choose a capacitor with a voltage rating higher than what your system will use.
The run capacitor is used in the motor to enhance its performance. They have high efficiency. When the capacitor is permanently connected to the circuit, then the power factor is maximum. It includes a high pullout torque. Capacitors can operate approximately for 10 years without maintenance.
