Capacitor values can vary by 30% or so, but not double. The larger cap would draw too much current, possibly overheating.
capacitor start induction run motor
It should work okay as long as voltage rating is equal to or greater than the capacitor you are replacing.
It sounds like the starting capacitor is about to give up.
capacitor start motor
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".
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.
No.
if it is a capacitor start and run motor, this is because of shorted capacitor
capacitor start induction run motor
Connect your start capacitor in series with the start winding.Connect the run capacitor in the common terminal and Line 1 of the power supply.
It should work okay as long as voltage rating is equal to or greater than the capacitor you are replacing.
No. You won't be able to start the motor without the capacitor.
It sounds like the starting capacitor is about to give up.
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.
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.
