Wiring a of changing a three-phase motor to a single-phase parallel capacitor

3) Changing the wiring of a three-phase motor to a single-phase parallel
capacitor     . Regardless of whether the windings are star-connected or delta-connected, they can be connected to single-phase by parallel capacitors. The wiring is
shown in Figure 3-19.
    When starting, press button SB. When the motor reaches the rated speed, disconnect SB. In the figure, cg is the working
capacitance, C. is the starting capacitor . They can be estimated according to the following formula:
    C. =Gui Curly: 亳cpF,; cn-c. ~4, Cc
in the formula j. ——Rated current of the motor, A;
    U-rated voltage of the motor, V;
  cosp-power factor, which can be 0.7~0.8 for small power motors.
