Let’s explore the details of this product with Thanh Thai Motor!

General design of the 3-Phase Electric Motor 0.55kW 0.75Hp

The 3-phase electric motor features a compact, sturdy design suitable for various installation spaces. The outer casing is made of cast iron or die-cast aluminum to enhance heat dissipation. The motor shaft is made of pure stainless steel to prevent rust and corrosion in any surrounding environment during use. The integrated rear cooling fan helps maintain a stable temperature during long-term operation.

Internal structure of the electric motor

Belonging to the 3-phase electric motor segment under 3.7kW, the internal structure consists of two main parts:

• Stator: The stationary part surrounding the outside, playing the role of generating a rotating magnetic field. This part contains evenly distributed copper windings, which generate alternating current when powered to activate the motor’s operation.
• Rotor: Located inside the stator, it is the main moving part. The rotor is composed of multiple thin technical steel sheets stacked and pressed tightly into a cylindrical shape, capable of continuous rotation within the stator’s magnetic field to produce mechanical work for the equipment.
• Motor shaft: Connected to the center of the rotor, made of stainless steel to transmit motion force directly to the outside to operate equipment.
• Bearing: Helps the rotor shaft rotate smoothly, minimizing friction and vibration when the motor is running.
• Cooling fan & fan cover: Attached to the rear of the motor to blow a continuous cooling airflow, maintaining a stable temperature.

Instructions for wiring a 3-phase electric motor

Step 1: Open the terminal box

• Action: Use a cross-head screwdriver to turn counterclockwise and remove the 4 screws at the 4 corners of the terminal box cover located on the motor body.
• Note: Keep the 4 screws and the rubber gasket (if any) neat so that when reinstalling the cover, the motor still ensures water and dust tightness.

Step 2: Identify terminal post locations

• Observation: When opening the cover, you will see a plastic terminal block with 6 ceramic posts (usually labeled U1, V1, W1 in the top row and W2, U2, V2 in the bottom row).
• Identify connection points: The technician in the instructional video connects 3 power lines to 3 aligned posts: U1, V1, and W1.
• Additional note: The thin copper bars between the posts (used to set Star or Delta running modes) are usually pre-arranged to match the voltage. In this simple wiring case, you only need to keep the current status of those copper bars.

Step 3: Proceed to connect the 3 power phase wires

• Preparation: You need 3 phase wires of a 380V power supply. (For safety and best contact, the ends of these wires should be crimped with U-shaped or ring terminals).
• Connection:
  • Connect the first wire to terminal U1.
  • Connect the second wire to terminal V1.
  • Connect the third wire to terminal W1.
• Tightening screws: Use needle-nose pliers or a small wrench to tighten the nuts on the posts securely. This is a very important step; if tightened loosely, the passing current will cause arcing, melting the terminal or causing short circuits and burnout.

Step 4: Power on and test run

• Ensure safety: Close the terminal box cover (in practice, you should properly screw it back on to prevent short circuits before powering on).
• Test run: Turn on the circuit breaker to supply 380V power to the motor. The motor shaft will start to rotate.
• Troubleshooting tip: If you find the motor rotating in the opposite direction of your machinery’s requirements, you simply need to disconnect the power, open the terminal box, and swap any 2 power wires (e.g., switch the wire at terminal U1 to V1 and vice versa) so the motor will rotate in the forward direction.
