What is capacitor start induction motor?
Capacitor-start induction motors have a capacitor in series with the starting winding to create a phase shift and create a rotating magnetic field. This provides higher starting torque and allows the motor to start under load.
A capacitor start induction motor is a type of electric motor that uses a capacitor to provide an initial boost of current to the rotor. This initial boost of current is needed to generate the magnetic field that is required to start the rotor of an induction motor.
In a capacitor start induction motor, the stator's magnetic field is not strong enough to generate the initial current that is needed to start the rotor. As a result, a starting capacitor is added to the motor to provide the additional current that is needed to start the motor.
The starting capacitor is connected in series with the start winding of the stator, and it provides a higher voltage to the start winding than is supplied by the power supply. This higher voltage causes a larger current to flow through the start winding, which in turn generates a stronger magnetic field. The stronger magnetic field is used to generate the initial current that is needed to start the rotor of the motor.
Once the rotor of the capacitor start induction motor has started, the starting capacitor is disconnected from the circuit, and the motor operates like a normal induction motor. The starting capacitor is only used to provide the initial boost of current that is needed to start the motor, and it is not needed during normal operation of the motor.
In summary, a capacitor start induction motor is a type of electric motor that uses a starting capacitor to provide an initial boost of current to the rotor. The starting capacitor is connected in series with the start winding of the stator, and it provides a higher voltage to the start winding than is supplied by the power supply. This higher voltage is used to generate the initial current that is needed to start the rotor of the motor, and the starting capacitor is disconnected from the circuit once the rotor has started.
