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.
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.
A capacitor start motor is an improved form of split-phase induction motor. In this motor, the starting winding has a capacitor in series with it. This type of motor was developed at a later stage and offers higher starting and running torque. A capacitor motor is also referred to as a capacitor start capacitor run motor.
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.
In a split phase motor, an electrolytic capacitor is used. It is connected in series with the starting winding along with the centrifugal switch S, as shown in the diagram. When the motor reaches approximately 75% of its synchronous speed, the starting winding is cut off. The motor's construction and winding are similar to those of a usual split phase motor.
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.
