6 FAQs about [How to install capacitors for old motors]

Do electric motors use a capacitor?

These electric motors use a capacitor to start and run the motor efficiently. We explain the choice & wiring procedures for a hard start capacitor designed to get a hard-starting air conditioner compressor motor, fan motor, refrigerator, or freezer compressor or other electric motor (such as a well pump) going.

What is a start capacitor in an electric motor?

In electric motors, capacitors are used for various purposes, including starting and running the motor. When an electric motor is switched on, it needs an initial boost of power to overcome inertia and start rotating. This is where a start capacitor comes into play.

When do you need a hard start capacitor?

When an electrical motor is having trouble starting, such as an air conditioning compressor motor, blower motor, a refrigerator motor or a freezer motor, or even a fan motor, the repair technician may install a simple and inexpensive hard-start capacitor.

What does a starting capacitor do?

Capacitors are electric devices that get an electric motor running at start-up by providing a "jolt" of stored electrical energy, or that help keep a motor spinning once it has started. The starting capacitor helps a motor start spinning by creating a high-torque, rotating, electrical field in the motor.

Can you put a starting capacitor on an electric motor?

HVAC suppliers sell general-use starting capacitors that are intended for use across a range of electrical motors and motor sizes. But at least some industry sources (Sealed Unit Parts Company or Supco) make a more careful argument explaining that it's best not to install a significantly oversized starting capacitor on an electric motor.

What are the different types of capacitors used in electric motors?

There are two main types of capacitors used in electric motors: start capacitors and run capacitors. Start capacitors are designed to provide the extra torque needed to start the motor and are typically connected in series with the start winding. They have a higher capacitance value and are only active during the starting phase.
