6 FAQs about [The motor has a capacitor]
What is a motor capacitor?
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).
What is a capacitor start motor?
Capacitor Start Motors are single-phase Induction Motors that employ a capacitor in the auxiliary winding circuit to produce a greater phase difference between the current in the main and the auxiliary windings. The name capacitor starts itself shows that the motor uses a capacitor for the purpose of starting.
Why does a motor need a capacitor?
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.
