1 and 220v motors consist of two parts, one rotor leads out these three lines, and a capacitor needs to be connected in parallel between the two lines.

2. Connect the red line of the blue line with the capacitor and leave the yellow line blank.

3. After the connection, connect the remaining yellow wire to the power supply, that is, the live wire of 220V, and then connect one of the remaining two wires to the zero line of the power supply, so that a loop can be formed, and the capacitor plays the role of starting the capacitor.

4. Therefore, the capacitor is connected to the motor.
