A capacitor is required for a single-phase motor to provide the necessary phase shift to start the motor and to improve its running efficiency. In a 1-phase motor, the starting torque is essential to overcome the initial inertia and bring the motor to its operating speed.
A motor capacitor 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 capacitor).
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.
Capacitors are used in single-phase motors to create a phase difference between the currents in the start and run windings. This phase difference creates a rotating magnetic field, which is necessary for starting torque and running the motor. That’s why a capacitor is necessary for a 1-phase motor.
Without a capacitor, the motor will lack the necessary phase shift to create a rotating magnetic field. As a result, the motor will either not start at all or will start slowly and with reduced torque. This can cause the motor to overheat and eventually fail.
Running Capacitors: These remain in the circuit during operation to ensure smooth running and improve efficiency. Starting capacitors are designed to boost the motor’s starting torque. When the motor is powered on, the capacitor helps overcome the initial inertia, allowing the motor to begin its rotation with ease.
