What is a split phase motor with relay and capacitor called?

A capacitor start motor is a split phase motor that uses a capacitor in series with the start winding to cause a greater phase shift, resulting in greater starting torque. It uses a centrifugal switch to switch out the start winding and capacitor once the motor is up to speed. I assume this switch is what you're referring to as a "relay".


Can you change a 440 volt 12.5 uF start capacitor with a 370 volt 12.5uF run capacitor?

There are two ways to read this: you have a burned-out run capacitor on your motor and a good start capacitor in your parts box, and you have a burned-out start capacitor and a good run capacitor. If the run capacitor's bad and you want to put the higher-voltage start cap in its place, the answer is yes. This is called derating, and the only thing it does for you is increases the lifespan of the capacitor because you're not working it as hard as it can take. If the start capacitor's bad, don't do this--they used a 440-volt capacitor in there for a reason.

Is a run capacitor the same as a start capacitor?

No, they are two different concepts. The start capacitor is used in conjuction with a starting winding on a single-phase induction motor to produce a small component of rotating field inside the motor. This ensures it rotates the desired way. The run capacitor is used to correct the power-factor of the motor, which reduces the current drawn from the supply for the same amount of power.

Can i not use a capacitor on a motor equipted with the motor?

No. You won't be able to start the motor without the capacitor.


Can you by-pass a capacitor in an electric motor?

You can not by-pass the capacitor in an electric motor. Most are capacitor-start motors which require the capacitor to be operational in order to start. If the capacitor is not working then it will need to be replaced.


How do you connect capacitor to a capacitor start motor?

A start capacitor is wired in series with the motor's start winding via a centrifugal start switch. The switch disconnects the capacitor and start winding once the motor has reached a pre-determined minimum speed. The motor then continues to run on its main field winding. A different design uses a "start-and-run" capacitor which remains in circuit whilst the motor is running.


Which device is used to change the rotation of a motor in washing machine?

A device called a motor capacitor is used to change the rotation direction of a motor in a washing machine. By changing the connection of the capacitor, the motor's direction can be reversed to rotate in the opposite direction.

How do you wire a three phase motor with capacitor start?

I have never come across a three phase capacitor start motor. Any three phase motors I have worked on are induction start.


What is the function of a pool motor capacitor and how does it contribute to the operation of a pool motor?

A pool motor capacitor helps start and run the pool motor by storing and releasing electrical energy. It provides the necessary power boost to start the motor and helps maintain a consistent speed during operation. Without the capacitor, the pool motor may struggle to start or run efficiently.
