1-Phase Electric Motor 4kW 5.5Hp

The 1-Phase Electric Motor 4kW 5.5Hp is an ideal choice for households and small production workshops. Operating stably on a 220V power supply, this line of electric motors delivers powerful operation, power saving, and long-term durability. Let’s explore with Thanh Thai Motor the details of the 1-phase electric motor that is currently trusted and leading the market.

General design of the 1-Phase Electric Motor 4kW 5.5Hp

The 1-Phase Electric Motor 4kW 5.5Hp has a sturdy design with a solid cast iron or cast aluminum motor body, providing optimal heat dissipation. The prominent feature to identify this motor line is 2 capacitors – including a starting capacitor and a running capacitor, symmetrically arranged on both sides of the motor body or integrated into the terminal box. With a smart design and neat structure, the motor is easy to install in many spaces, from workshop floors to civil machine frames.

Internal structure of the 1-Phase Electric Motor 4kW 5.5Hp

Technically, the 1-phase 4kW 5.5Hp motor includes:

• Stator: Consisting of a working winding and a starting winding. Due to the fairly large 4kW capacity, the windings are wound with pure copper with a large cross-section to handle heavy loads.
• Rotor: Squirrel-cage rotor type, designed to create strong starting torque, helping the machine easily overcome initial loads.
• Capacitor box: Contains 2 capacitors (starting capacitor and running capacitor to maintain power). This system helps the machine run smoothly and achieve the highest efficiency.
• Housing: Cast iron housing provides optimal heat dissipation for the 4kW capacity.
• Bearings: Uses high-quality ball bearings, capable of withstanding heavy loads and large vibration forces when the machine operates for a long time.

What types of 1-Phase Electric Motor 4kW 5.5Hp are available?

The 1-phase 4kW 5.5Hp motor line is usually popular in 2 main speed levels:

1-Phase Electric Motor 4kW 5.5Hp 2-pole (2.800 – 3.000 rpm)

This motor line is optimized for systems requiring high rotational speed, increasing working productivity for equipment requiring large revolutions per minute without going through overly complex reduction gearboxes.

Applications:

• High-pressure water pump: Serving large-scale irrigation, high-head water pumping for high-rise buildings or automatic irrigation systems, ensuring strong and stable output water flow.
• Industrial exhaust fan: Smoke extraction, dust collection, and workshop cooling systems requiring large air volume and strong wind velocity to effectively remove polluted air or heat in the production environment.
• Iron cutting machine: Ensuring sharp and fast cutting lines for handheld or benchtop tile and steel cutters, high speed helps the material surface after cutting be smooth and minimizes burrs.
• Booster pump: Used in water treatment systems or industrial water supply requiring high output water pressure, helping to maintain strong water pressure at the end points of the pipeline system.

1-Phase Electric Motor 4kW 5.5Hp 4-pole (1.400 – 1.500 rpm)

This is the most favored motor line thanks to its smooth operation, high pulling force (torque), and durability in continuous heavy-load applications.

Applications:

• Air compressor: Providing stable pulling force for piston air compressor heads in mechanical workshops and auto garages, helping to ensure stable compressed air flow to operate pneumatic equipment such as impact wrenches, paint sprayers, or industrial dust blowers. Agricultural product grinder: Grinds corn, potatoes, cassava into bran, effective for small and medium farms; high torque helps the machine not to jam when grinding dry, hard, or high-fiber materials.
• Feed pellet machine: Creating strong pressing force to form animal feed pellets, the motor runs with durable load to help the pressing mold reach a stable temperature, producing smooth, solid, and non-crumbly feed pellets. Merchandise conveyor: Operates heavy goods and packaging conveyor systems in warehouses, supporting smooth startup for long conveyors with large cargo volumes on the surface.
• Food mixer: Mixing dough and pureeing food in industrial production lines, ensuring uniformity for high-viscosity materials without causing motor overload during continuous operation.

Which gearboxes can the 1-Phase Electric Motor 4kW 5.5Hp be combined with?

The 1-Phase Electric Motor 4kW 5.5Hp can be combined with various types of gearboxes such as:

• Worm gearbox: WPS, WPX, WPO, WPA, WPDS, WPDX, WPD0, WPDA size 120 and NMRV 110, 130 gearboxes.
• Heavy duty gearbox: R-series inline helical gearbox, S-series helical worm gearbox, F-series parallel shaft helical gearbox.

In addition, it can also be combined with:

• pulley and coupling: 28mm, 38mm, 42mm shafts.
• Brake: Specialized type for 1-phase 4kW 5.5Hp motor.

Instructions for wiring the 1-phase electric motor

Supplying power to a 1-phase 3.7kW motor requires precise operation due to the large starting current. You can watch electric motor videos in advance to understand the terminal positions.

Step 1: Remove the terminal box cover

Use a screwdriver to remove the screws and open the capacitor box cover on the motor body. Inside are the wire terminals from the electrical winding and capacitors.

Step 2: Prepare cables and protective equipment

Use 2-core power cables with a cross-section of 4.0mm – 6.0mm. Connect power through a 30A – 40A CB (Circuit Breaker).

Step 3: Connect the 220V power supply

Identify 2 power supply terminals (usually marked Z1, U1 or according to the diagram printed on the box cover). Connect 2 power wires (L and N) of 220V to these 2 terminals. Use a wrench to tighten the nuts to ensure electrical contact, avoiding heat generation and arcing.

Step 4: Operation and rotation direction check

Close the cover, turn on the CB to test run. If the shaft rotates in the reverse direction of the driven machine, cut off the power, and swap the positions of the 2 wire ends of the running winding (working winding).

Note: If the diagram is blurred or it is difficult to identify the wire ends, please refer to the summary videos on how to measure and wire to ensure correct operation.
