Field Wiring For Single-phase Motors

(1) Power wiring: connect the live wire and neutral wire of the power supply (220V or 110V AC power) into the terminal board of the motor, generally L1, L2, and public line N.

(2) Starting circuit wiring: commonly used starting methods are capacitor start, resistance start and self-start. When the capacitor starts, connect the capacitor to A/B (or L1/L2), and connect one end to the start end and the other end to the running terminal; When the resistor starts, the resistor is connected to the circuit to generate additional torque at the start of the motor, allowing it to start smoothly. When starting up, it is directly connected to the running end and the starting end, and the starting torque is generated at the moment of starting, so that it can start smoothly.

(3) Protection wiring: access overload protection switch, thermal relay, etc. to ensure that the motor is automatically powered off under abnormal conditions such as overload and exceeding the rated temperature to avoid motor burnout.
