What is Start Capacitor? | Animation | HVAC | Electrical

A start capacitor is an electrical component used in some types of electric motors to aid in the motor's startup process. It is a type of capacitor designed to provide an initial surge of electrical energy to the motor's auxiliary winding during startup. This surge of energy creates a rotating magnetic field that enables the motor to overcome inertia and begin rotating.

Start capacitors are characterized by their relatively high capacitance values and are typically used in single-phase motors, where an additional boost during startup is required. Once the motor reaches a certain speed, a mechanism like a centrifugal switch disconnects the start capacitor from the circuit to avoid continuous operation, as it is not needed beyond the initial startup phase.

The purpose of a start capacitor is to help single-phase motors start efficiently and reliably. It is an essential component in various applications, including air conditioners, refrigerators, compressors, and other small appliances that utilize single-phase electric motors.

Thank you.

That was good and an easy explanation that people can understand. Thanks

[cosmicdust]

actually this is wrong as many people do. energy stored in a staring capacitor is too small to move a motor stator. you need to underhand the phase principle of a induction motor.

A capacitor is like a battery but discharges much faster and does not store a charge for as long. the reason you need a capacitor is because there is not enough power on an average 110 circuit/available circuit, a capacitor gives a sudden increase in amperage during Break of inertia to start the electric motors

❤thank you boss for your explanation

[kentkentkent]

This is the best explain ever heard and now I'm clear!

So the start capacitor is always connected to the power source?! Wouldn't that significantly reduce its life span (since it's always changing polarities due to AC)?

your videos are really helpful ...thanks for sharing ...
if you don't mind can I get a idea where you are making (software name )videos .

[rukayakhatun]

You videos is realy good but I am not understand properly

[Domaro]

Some units doesn't have a starting capacitor...
