There are many different 'run' capacitors on motors. It depends on the motor make and use. You need to consult your manual or local electric motor shop.
See related links below for good information on how capacitors effect motor starting.

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.
Why can a run capacitor with a single phase motor remain in circuit after the motor starts?
Because from the capacitor characteristics at first it will charge and then it will stsrt to run so when the motor get power from single phase capacitor take time for charging. Amit.
Why does the run capacitor have a lower MFD rating than the start capacitor?
The run capacitor has to absorb the VARs while the motor is running, but the start capacitor has to provide running current to start the motor. The latter is higher, so more microfarads are needed to pass the greater current. Current in a capacitor is 2pi x frequency x capacitance x voltage so, on a 240 v 50 Hz system, 100 mfd would take 2pi x 50 x 100 x 10-6 x 240 amps, and that is multiplied by the voltage 240 to find the VARs.
Why capacitor is used in ceiling fan?
Capacitor helps a motor generate a starting torque. once the torque is produced and motor rotates capacitor acts as a current path. technically capacitor creates a phase difference.
What is function of run capacitor?
Start and run capacitors are normally used in AC motors to aid in starting and running efficiency. Both capacitors are wired in series with the start winding of the motor. The reason they are not both called start capacitors is that the start capacitor gives the motor more torque to overcome the fact that it is at standstill, and then automatically disconnects itself from the circuit. The run capacitor gives the motor better running efficiency and remains part of the circuit, it is therefore called the run capacitor. Three phase motors are able to start more effectively due to the nature of three phase power. These capacitors will likely be found in single phase AC motors. This is because a single phase AC source rises and falls from zero, in a three phase source the second phase sine wave starts going upward before the first phase wave has a chance to fall completely to zero. Thus a three phase motor spends more time per cycle at its rated voltage than the single phase motor, and has an easier time starting instantaneously.
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.
How many microfarad of running capacitor is best for a 1.5 hp motor?
There are many different 'run' capacitors on motors. It depends on the motor make and use. You need to consult your manual or local electric motor shop.See related links below for good information on how capacitors effect motor starting.
Why does a heater blower have a humming noise when the motor is running?
If the heater blower has humming noise when motor is running, first check its capacitor. If the capacitor is fine, then the motor is the problem and may need to be replaced.
My motor is 220volt single phase what voltage should the starting capacitor be The capacitor that is in it is only rated at 125 volt 500 MFD This is a 2 HP motor?
The voltage rating for a start capacitor must be at equal to the motors line voltage or greater.The formula used to find the value of a motor starting capacitor is 2650 X FLA/VAC = mfd.See related link below, page 462 to 465 for full details about motor capacitors
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.
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.
How many microfarad of starting capacitor is best for 15hp 3phase motor?
Starting capacitors are only required for single-phase induction motors. They are not necessary for three-phase motors.
What makes a capacitor go bad?
Too high of voltage, bad motor the capacitor is running , or power surge
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
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 motor is used for running lathe spindle?
Single phase induction motor ( usually capacitor- start type)
What type of induction motor is used in table fan?
Motor used in Table Fan is Split phase Motor(Continuous Running with Capacitor).It has Two winding Running coil + Starting Coil. Running coil connected Direct to Supply Starting coil Connected is series with capacitor than parallel with power.
