The circuit of the 3-phase motor powered by the single phase

To run a 3-phase motor with a single power supply, we just need a proper phase drifting capacitor, the methods are as follows: for the motor of star connection, whose connection is shown in figure 1; for the motor of triangular connection, the connection is shown in figure 2. According to the practice, the value of the volume in the phase-drifting capacitor should be equal to the product of 0.07 and the motor power, for example, the power of the motor is 150W, and the volume of the capacitor is equal to 0.07 x 150=10.5uF, so the need can be met by connecting two sunlight lamps (4.75μF) in parallel way.
