eli5 How do capacitors work with single phase electric motors?
Hmm I wouldn''t necessarily say that capacitors add torque, a single phase motor by itself is not self starting, however a single phase is enough to maintain the motor running. So a starting circuit with a capacitor is used to start the motor. In a DC circuit a capacitor will slowly build up a charge to saturation, then hold the charge.
Why capacitor is required for Single phase motor
Why capacitor is required for Single phase motor: Single phase motors are not a self-starting motor, single phase power supply cannot create rotating magnetic field because of its nature (only one phase). So that to rotate the single phase motor we have to give rotary
When and when doesn''t a motor need a start capacitor and why?
Simple: AC motors need a startup capacitor, DC motors do not. The capacitor is only there to shift the current out of phase from the voltage so the motor can begin turning. Once the motor is turning, the capacitor doesn''t do much. If it is a two or three phase power system, the motor doesn''t need a cap to start because the current is already

6 FAQs about [Why do single-phase motors need capacitors ]
Why is a capacitor necessary for a 1 phase motor?
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.
Does a single phase induction motor need a capacitor?

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.
How does a single phase motor work?
When a single-phase motor is powered, the capacitor creates a phase difference between the current in the start winding and the current in the main winding. This phase shift generates the rotational motion necessary to start the motor. Without this assistance, the motor would not be able to overcome inertia and begin rotating.
How to rotate a single phase motor?
So that to rotate the single phase motor we have to give rotary moment or manual rotation to get continuous rotation. But at that same time we can run the motor but adding extra starting winding and the winding will be connected in series with the capacitor. Technically it is called split phase capacitor method.
