3. The connection method of the three-phase motor
The connection mode of the three-phase motor mainly involves the access mode of the power supply and the winding connection mode inside the motor. Here are some common ways to connect:
1. StarConnection: In this connection, the ends of the three-phase windings are connected to form a central point, and the power supply is connected to the beginning of each winding separately. It is suitable for the situation of light load or normal operation of the motor.
2. DeltaConnection: In this connection method, the three-phase windings are connected end to end to form a closed loop. Ideal for situations where the motor is heavily loaded or higher power is required.
Fourth, the connection steps and precautions of 4.5hp three-phase motor
Connection Steps:
1. Choose the appropriate connection (star or triangle) according to the rated power and working load of the motor.
2. Make the correct wiring according to the identification or instructions in the junction box of the motor.
3. Make sure all wiring is secure and free of exposed parts to avoid the risk of short circuit or electric shock.
4. Check that all wiring is correct before turning on the power.
Notes:
1. Always disconnect the power supply before making any electrical connections to avoid the risk of electric shock.
2. Make sure the grounding wire of the motor is properly connected to ensure safety.
3. Carry out the correct wiring operation according to the instructions for the use of the motor, and do not change the internal wiring method of the motor at will.
