You can get away with a 30% or so larger capacitor.

Can you replace 1.7 microFarad capacitor with 2 microFarad capacitor of capacitor start motor?

It should work okay as long as voltage rating is equal to or greater than the capacitor you are replacing.


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.


Why the oil filled capacitor is used in permanent split capacitor motor?

An oil filled capacitor is used in (PSC) motor because the capacitor is in the circuit the whole time the machine is running. The capacitor is oil filled to cool it due to being in circuit the whole time


In an electric motor can you replace a start capacitor with 300 MFD with one with 600 MFD?

Capacitor values can vary by 30% or so, but not double. The larger cap would draw too much current, possibly overheating.


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 a motor receive too little power and burn out the start capacitor'?

no


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.


What are the starting and running characteristics of a capacitor-start motor?

Easier to start up. Running remains the same unless it is equipped with a run capacitor too. A run capacitor uses a little less current during run and probably runs a little cooler too.


Can a larger capacitor be used in an air conditioner?

Function of Capacitor in Air Conditioner:Compressor Motor Capacitor: This air conditioning capacitor usually consists of two capacitors that are combined. This vital capacitor gets the motor running in the air conditioning unit.Start Capacitor: This capacitor provides auxiliary support and that is not a standard on every air conditioning unit. It can give the motor a boost to get it started.Indoor Blower Motor Capacitor: This capacitor is self-explanatory. It is responsible for starting the indoor-blower-motor and keeping it running efficiently.Outdoor Fan Motor Capacitor: The name says it all for this capacitor. It starts the outdoor fan and keeps the air flowing through the coils that run on the outside of an air conditioner.

What is the value of capacitor for 1hp ac motor?

The value of the capacitor for a 1hp AC motor depends on the specific motor design and manufacturer guidelines. It is important to consult the motor's documentation or contact the manufacturer to determine the correct capacitor value for proper motor operation.


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.


How do I replace a fan capacitor?

To replace a fan capacitor, first turn off the power to the fan. Locate the capacitor, usually found near the fan motor. Discharge any stored electricity by using an insulated screwdriver to short the terminals. Note the wiring connections and remove the old capacitor. Install the new capacitor in the same position and reconnect the wires. Turn the power back on and test the fan to ensure it is working properly.


What is the common application for capacitors in electric motors?

There are 2 types of capacitor including starting capacitor and running capacitor running capacitor are used to improve the power factor of motor. starting capacitor used in split phase induction motor . starting capacitor may isolate from motor,s starting winding through of centrifugal switch after getting motor 90% of it,s rated speed.
