wound metallised foil capacitors with impregnated paper (MKP capacitor).
For the operation of a three-phase motor on the single-phase network (stone-setting circuit), normally approximately 70 μF per kW shall be provided. Example 0,37 kW three-phase motor times 70 uF, then corresponds to 25 uF.
The capacitance of a capacitor for a single-phase motor is approximately 30-50μF per kW of motor power output, provided that the main and auxiliary windings have the same number of turns.
