What is the use of having capacitors in fans, cooler motors or other electric motors ?
They are used to help start the motors. There are also running capacitors.mkbh_10 said:What is the use of having capacitors in fans, cooler motors or other electric motors ?

Can we charge a capacitor by DC , if yes then how ? Why does capacitor allow ac to flow through but not dc . For 3rd part i know frequency of dc is zero but in practical terms how will it be explained ?
A capacitor in an electric motor helps to improve the motor's starting torque and power factor. It also helps to regulate the motor's voltage and reduce electrical noise and interference.
When an electric motor starts, it requires a high level of torque to overcome its own inertia. A capacitor helps to provide this initial surge of power, which allows the motor to start quickly and smoothly.
Power factor is a measure of the efficiency of an electric motor. It represents the ratio of the actual power used by the motor to the apparent power it draws from the power source. A capacitor helps to improve power factor by reducing the amount of reactive power needed to run the motor, making it more efficient.
Aside from improving starting torque and power factor, capacitors also help to reduce electrical noise and interference, which can prolong the lifespan of the motor. They also help to regulate the motor's voltage, which can prevent damage to other components in the motor.
In most cases, yes. However, it is important to consult the manufacturer's specifications and recommendations to ensure that the capacitor is compatible with the motor and will not cause any damage. It is also important to have a professional install the capacitor to ensure it is done correctly and safely.
