Technical parameter

More information of motor capacitor

The calculation formula of the working capacitance of a single-phase motor: GC=1950I/Ucos∮ (uF) where:

I: motor current, U: single-phase supply voltage, cos∮: power factor, take 0.75, 1950: constant

Note: If the single-phase electricity is 220Vrms, then:

GC=1950I/Ucos∮=1950P/(U^2)cos∮=1950*P/(220*220)*0.75≈0.03*P(uF), where P is the motor power. After calculating the working capacitance of the single-phase motor, the starting capacitor is 1-4 times of the working capacitance (the larger the starting capacitor, the greater the starting current (the greater the interference to the external power grid), the starting torque increases, and the faster the start.

Conversely, if the starting capacitor is smaller, the smaller the starting current (the smaller the interference to the external power grid), the smaller the starting torque, and the slower the start-up. The withstand voltage must be greater than the maximum peak of the AC input voltage (220Vrms*1.414≈311), and the withstand voltage of 400V or higher can be taken.
