To size a capacitor for a motor, you need to consider the motor’s specifications and the type of capacitor required (start or run). The basic formula for sizing a run capacitor is approximately 0.1 to 0.2 μF per horsepower, and for a start capacitor, it’s around 100 to 200 μF per horsepower.
A motor capacitor is a device that stores and releases electrical energy in a circuit. It's essential for starting and running electric motors by providing the necessary reactive power. The size of the capacitor determines the amount of energy it can store, making the accurate calculation of the size paramount to motor functionality.
The run capacitor will usually be attached to the exterior of the motor under a bulged cover such as in our photo below. This motor has two external capacitors: start & run (yellow arrows). You'll know which is which by examining the wiring and capacitor markings. The Capacitors is Inside the electric motor?
The formula for calculating capacitor value is C (µF) = (P (W) x η x 1000) / (V (V) x V (V) x f) Look at the formula, the required capacitance value is directly proportional to the motor power. Hence while increasing the motor size, the size of capacitance also will be increased.
These caps will have three electrical terminals: So if your electric motor has only one physical capacitor, it might be a model that combines both start and run features. You can tell this by examining the terminals marked on the capacitor. It will have both S and R as well as a C terminal.
'f' is the frequency in Hertz. 'V' stands for voltage in volts. Consider a single-phase motor with a power of 1000W, voltage of 230V, power factor of 0.8, and frequency of 50Hz. Inputting these values into the calculator using the formula, we find the appropriate capacitor size to be approximately 481.3μF.
