3-Phase Electric Motor 0.8kW 1Hp

The 3-Phase Electric Motor 0.8kW 1HP belongs to the small-sized drive equipment category, operating on a 380V industrial power supply. The product provides basic kinetic energy for light machine tools, mini conveyor systems, and mechanical mechanisms in space-limited workshops.

Overview Design of the 3-Phase Electric Motor 0.8kW 1HP

The housing of the electric motor is designed to be compact to optimize weight while maintaining mechanical durability.

Manufacturers typically use die-cast aluminum alloy for the motor housing to increase heat dissipation speed. The outer surface features a series of vertical ribs to expand the air contact area. The terminal box is positioned on top of the frame, equipped with a rubber gasket for dust and water resistance meeting IP55 standards.

Internal Structure of the 3-Phase Electric Motor 0.8kW 1HP

To ensure continuous operation at a 0.8kW load, all internal components are manufactured according to current technical standards.

• Stator: Stationary magnetic core stamped from high-quality electrical steel sheets. The internal windings are made entirely of pure copper, vacuum-impregnated with class F heat-resistant insulating varnish.
• Rotor: One-piece cast squirrel-cage rotor undergoing a dynamic balancing process to ensure smooth rotation and eliminate centrifugal forces causing vibration.
• Bearings: Centering ball bearings at both ends of the shaft, featuring dust caps and industrial-standard lubricating grease.
• Cooling system: Centrifugal plastic cooling fan mounted at the shaft end, continuously generating airflow along the motor housing.

Applications:

• Light goods lifting winch mechanisms in warehouses requiring extremely slow lifting/lowering speeds to ensure absolute safety.
• Biological thick sludge agitators, ultra-slow coagulation mixers.
• Slow-moving spiral tunnel conveyors.

Which Gearboxes Can the 3-Phase Electric Motor 0.8kW 1HP Be Coupled With?

Thanks to its compact dimensions and standard shaft diameters (19mm, 24mm), the 0.8kW 1HP motor is extremely easy to couple with the following gearboxes:

• Cast iron worm gearbox: Models WPA, WPS, WPX, WPO… (recommended small sizes such as 50, 60, or 70).
• Aluminum housing worm gearbox: The NMRV series is very popular; size 040 or 050 is recommended to optimize aesthetics and compactness.
• Heavy-duty helical gearbox: Models R, S, F (small sizes) for high-automation conveyor applications.
• Other accessories: Combines well with pulleys, small chain sprockets, or additional brake motor assemblies (0.8kW 1HP) for emergency braking.

Instructions for Wiring the 3-Phase Electric Motor

To ensure precise and safe operation, you should first consult electric motor videos to clearly understand the internal structure and terminal block positions inside the motor.

Step 1: Remove the Terminal Box Cover of the Electric Motor

Use a suitable screwdriver to remove the 4 fixing bolts on the terminal box cover. After opening the cover, you will see the system of wiring terminals. With a common 3-phase motor, this area typically has 6 clearly labeled wire ends.

Step 2: Identify the Terminals and 380V Power Supply

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

Step 3: Connect the 3-Phase Power Supply to U1, V1, W1

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

Important Safety Note:

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

Step 4: Close the Cover and Test Run

After completing the wiring, tightly close the terminal box cover and secure the bolts to protect the equipment from dust and moisture. Apply power to check operation. If the motor rotates in the opposite direction of what is desired, simply disconnect power and swap any two of the three phase wires to reverse the rotation direction.

Following the correct procedure not only helps the system operate stably but also ensures long-term safety. Electric motor videos from Thanh Thai Motor will serve as a useful reference source for users during practical operation.
