Explore more details about the structure, characteristics, and applications of this 1-Phase Electric Motor 2.2kW 3Hp with Thanh Thai Motor.

General design of the 1-Phase Electric Motor 2.2kW 3Hp

One of the most easily recognizable features of the 1-phase electric motor is its dual-capacitor structure. These capacitors can be arranged separately or placed together in the terminal box, usually located on both sides of the motor body. Based on this characteristic, users can quickly distinguish 1-phase motor lines from other types of motors on the market.

Internal structure of the 1-Phase Electric Motor 2.2kW 3Hp

This product line is categorized among electric motors under 3.7kW, typically applied to small and medium-sized equipment. The basic structure includes the following main components:

• Motor housing: Made of cast iron or aluminum with good heat dissipation, protecting internal components and helping the motor operate durably.
• Capacitor: Plays a role in starting and maintaining stable operation. Depending on the design, the capacitor can be located separately or shared in the terminal box.
• Stator: The stationary part of the motor, completely wound with copper wire to enhance transmission efficiency.
• Rotor: The rotating part of the motor made from a high-quality steel core, generating a magnetic field during operation.

Instructions for wiring a 1-phase electric motor

The power supply process for a 1-phase electric motor must be performed carefully due to the large starting current. Before operation, you should review the electric motor videos to correctly identify the terminal positions.

Step 1: Remove the terminal box cover

Use a screwdriver to remove the fixing screws and open the capacitor box cover on the motor body. Inside is the wiring harness connected from the electric coils and capacitors.

Step 2: Prepare wires and protection devices

Use a 2-core electric wire with a cross-section from 4.0mm to 6.0mm. Power should be supplied via a 30A to 40A circuit breaker (MCB) to ensure safety during use.

Step 3: Connect the 220V power supply

Identify the two power supply terminals (usually labeled Z1, U1 or according to the diagram on the box cover). Proceed to connect the two L and N wires to the correct positions, then tighten the nuts to ensure good contact, minimizing heat generation and electric sparks.

Step 4: Operate and check the rotation direction

After wiring, close the electrical box cover tightly and supply power for a test run. If the motor rotates in the reverse direction, disconnect the power and swap the two ends of the run winding to reverse direction.

Note:

In case the wiring diagram is unclear, refer to the comprehensive video on measuring and identifying wire ends to ensure correct and safe implementation.
