Guide to wiring a 3-phase electric motor

Step 1: Remove the terminal box cover

• Use a screwdriver to turn counterclockwise to remove the 4 screws at the 4 corners of the terminal box cover located on top of the motor.
• Lift off the protective cover to access the terminal block inside.

Step 2: Analyze the terminal board and determine the power supply position

• Inside the terminal box, there are 6 terminal posts. You will see these posts are pre-linked together by copper bars (jumpers) to shape the connection type (Star or Delta).
• Your task is to supply power to the 3 posts in the outermost row. Technicians have clearly indicated the order of these 3 posts as: U1, V1, and W1.

Step 3: Connect the 3-phase power supply wires

• Take 3 wires of the 3-phase 380V power supply (corresponding to the 3 clamp ends in yellow, red, and blue-black).
• Firmly attach/clamp these 3 wires to the 3 posts U1, V1, W1 [00:00:40 – 00:00:55]. (Tip: If after connection the motor rotates in the opposite direction of your requirement, you just need to disconnect the power and swap the positions of 2 out of these 3 power wires).

Step 4: Tighten the contact points (Mandatory operation)

• The technician uses needle-nose pliers to grip and tighten the nuts on the 3 posts U1, V1, and W1 immediately after attaching the wires.
• This tightening ensures the best electrical contact area, preventing loose wires causing arcing (electrical sparking), voltage drops, or burning/short circuits when the machine operates at high intensity.

Step 5: Turn on power and run a test

• After making sure the connections are safe and well-insulated, proceed to close the switch to supply power to the motor.
• Observe the yellow rotating shaft (spindle). If the motor shaft rotates evenly, smoothly, and reaches a stable speed, the wiring process is completely successful
