Now, let’s explore more about this 3-Phase Electric Motor 22kW 30Hp with Thanh Thai Motor!

General Design of the 3-Phase Electric Motor 22kW 30Hp

The 3-phase electric motor is designed with a durable structure and high load-bearing capacity, suitable for heavy industrial environments. The outer casing of the electric motor is made of sturdy cast iron or aluminum alloy, providing excellent protection for internal components and enhancing heat dissipation. The rear cooling fan provides continuous cooling, ensuring stable performance during continuous operation.

Internal Structure of the 3-Phase Electric Motor 22kW 30Hp

To maintain high performance and long-term durability when carrying a 22kW load, the internal component assemblies of the motor are assembled from internationally standardized engineering materials:

• Stator: The stationary component containing the magnetic field, pressed from high magnetic orientation silicon steel sheets. The internal winding wire uses 100% pure copper, impregnated with high-grade insulating varnish (Class F) to prevent electrical discharge and withstand heat during continuous operation.
• Rotor: A solid die-cast squirrel-cage rotating core, integrated with guide bars made of aluminum alloy or pure copper. The rotor undergoes a computerized dynamic balancing system to completely eliminate vibration and centrifugal noise.
• Bearings: Installed at both ends of the shaft for centering, using reputable industrial bearing brands capable of withstanding high torsional and axial loads.
• Cooling System: Uses a high-strength synthetic plastic or aluminum alloy fan blade, combined with a protective guard at the rear to continuously draw in air and push it through the heat sink ribs of the motor body.

• Large Hollow Shaft / Worm Gearboxes: Can be paired with vertical worm gearboxes (such as WPA, WPS size 135 or 155) used in lifting mechanisms or mixing tanks.
• Belt Drive and Coupling Transmission: It is mandatory to use heavy-duty flanged couplings, gear couplings, or multi-groove C-type pulley systems (3 – 4 grooves) to protect the motor from shock loads during jamming.

Guide to Wiring a 3-Phase Electric Motor

Before proceeding, you should refer to electric motor videos to understand the structure and location of the terminal blocks, making operations more precise and safer.

Step 1: Open the Terminal Box Cover

Use a suitable screwdriver to remove the 4 fixing bolts on the terminal box cover. Once opened, you will see the internal terminal system. For a common 3-phase motor, this area typically has 6 clearly labeled leads.

Step 2: Identify the Terminals and 380V Power Source

The leads are arranged in two rows. The bottom row, labeled U1, V1, W1, is the position used to supply the input power.

Step 3: Connect the 3-Phase Power Supply

Prepare 3 phase wires from the 380V power source and connect them sequentially to terminals U1, V1, W1. Ensure correct positioning for stable motor operation.

Safety Note:

Terminal lugs must be tightened to ensure good electrical contact, preventing electric arcs that cause short circuits and fires. Do not connect power to the top terminal row (U2, V2, W2) as this may damage the windings.

Step 4: Finalization and Test Run

After wiring is complete, securely close the terminal box cover and tighten the bolts to protect the equipment. Supply power to check operation. If the motor rotates in reverse, disconnect the power and swap any two of the three phase wires to reverse the rotation direction.

To better understand advanced wiring methods as well as practical troubleshooting, you can refer to the compiled video in the electric motor video category, which provides a lot of detailed and intuitive instructional content.
