When replacing these capacitors, the capacitance value and voltage should be taken from the manufacturer’s plate on the motor or from the old capacitor.This must be correct within ±5% and is sometimes stipulated down to a fraction of a μF.The choice of a running capacitor is even more limited than with a starting capacitor.
When install a motor using capacitor for starting or running methods,we must sizing the rated of capacitor suitable with motor to get correct starting torque and avoid winding from overheating and can cause a damage.
These electric motors use a capacitor to start and run the motor efficiently. We also explain the choice & wiring procedures for a hard start capacitor designed to get a hard-starting air conditioner compressor motor, fan motor, refrigerator, or freezer compressor or other electric motor (such as a well pump) going.
Typical Motor Driver Board Showing Large Bulk Capacitors Experienced engineers often use general guidelines about bulk capacitance to select the capacitor values. One such guideline says to use at least 1 to 4μF of capacitance for each Watt of motor power.
Select a replacement capacitor whose capacitance value in µF, (micro-farads) typically expressed as a range such as 30 µF - 50 µF matches the original capacitor and/or the data tag on your electric motor. The voltage rating of a capacitor indicates the highest nominal voltage at which it is designed to operate.
To select the correct capacitance value, start with 30 to 50μF/kW and adjust the value as required, while measuring motor performance. We also can use this basic formula to calculate capacitor sizing : 2) Determine the voltage rating for capacitor. • Safety agency requirements.
