Two reasons could be that the motor was wired incorrectly or the load that the motor is driving is too heavy for the HP of the motor.

What are the capacitor effects on a single phase induction motor?
As anything to do with timing values for an electronic system of controlling a motor. Based on the question, the simple answer is that the capacitor causes a 90 degree lead which allows the motor to have a magnetic shift which causes the motor to start rotation.
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.
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
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".
What is run capacitor in single phase motor starter with three wire?
A run capacitor and a starter capacitor are not the same thing. A run capacitor is energized the entire time the motor is running, and a start capacitor is not. A run capacitor is one that changes the current on the windings of a single phase AC induction motor to create a rotating magnetic field to energize a second-phase winding. A start capacitor increases starting torque, allowing a motor to be turned on rapidly. It stays in the circuit only long enough to bring the motor to 3/4 of full speed. Some motors then continue to run with a run capacitor.
Can a run capacitor start a blower motor running it slow and causing it to overheat or is it a bad motor?
Yes, a bad capacitor causes blower motor to become slow or stop. Since bad or shortcapacitor will make the surge of current and tripping of circuit breaker.

Why do you connect a capacitor with an Ac motor?
The capacitor is used to create a second phase from the single phase power source and it is the interaction between these two phases that causes the motor to turn.
What causes engine to overheat 91 caprice?
The lack of air intake designed to flow into the motor.

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.
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.
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.
What causes the air condition fan not to come on?
faulty thermostat, stuck fan relay, bad fan motor, no voltage to motor, bad circuit board, bad run capacitor...
