Internal structure of the motor

Below is an overview description of the structure of the 3-Phase Electric Motor 38kW 50Hp:

• Stator: This is the stationary part of the motor, consisting of a core (assembled from high-quality electrical steel sheets) and copper windings wound around the core. The stator serves to generate a rotating magnetic field to provide energy for the motor to operate.
• Rotor: The part located inside and rotating under the action of the magnetic field generated by the stator. The rotor (usually of the squirrel-cage type) is made of good conductive materials such as copper or aluminum, serving to convert electrical energy into mechanical energy.
• Motor shaft: Attached to the center of the rotor, made of super-durable alloy steel. The shaft is responsible for transmitting torque (rotating force) from inside the motor to the external load equipment.
• Bearing: Located at both ends of the motor shaft. This component helps minimize friction when the shaft rotates, supports rotor centering, and withstands both radial and axial loads, helping the machine run smoothly.

Instructions for wiring a 3-phase electric motor

Step 1: Open the terminal box cover

• Prepare a suitable screwdriver.
• Proceed to remove the 4 fixing screws at the 4 corners of the terminal box cover located on the motor body.
• Open the cover to access the terminal blocks inside.

Step 2: Proceed to connect the power supply wires

• Prepare a 3-phase 380V power supply including 3 phase wires.
• Inside the terminal box, you will see the terminal studs. Proceed to connect the 3 power wires one by one to the 3 contact studs labeled U1, V1, and W1.
• Note: Use needle-nose pliers or a small wrench/socket to tighten the nuts firmly at the connection points. This helps ensure good electrical contact, avoiding sparking or short-circuiting during motor operation.

Step 3: Power up and test operation

• After securely connecting the 3 phases, check once more to ensure no wires are exposed or touching the motor housing.
• Turn on the circuit breaker to supply 380V power to the motor.
• Observe the motor shaft rotation to assess stability and smoothness, and check whether the rotation direction matches the requirement of the load equipment. (If you want to reverse the rotation direction, simply swap the positions of 2 out of the 3 supplied phase wires).
