1-Phase Electric Motor 0.18kW 0.25Hp

The 1-Phase Electric Motor 0.18kW 0.25Hp is a small-capacity electric drive motor series, suitable for civil and light industrial machinery systems. This 1-phase electric motor operates on standard 220V electricity, capable of efficiently converting electrical energy into mechanical energy, saving power, and being easy to install. This is an ideal choice for small machinery such as agitators, mini water pumps, food roasters, industrial fans, etc.

General design of the 1-Phase Electric Motor 0.18kW 0.25Hp

The 0.18kW 1-phase electric motor features a compact design, aesthetic styling, and is easily recognizable by its characteristic capacitors (run capacitor or auxiliary capacitor) – helping users easily distinguish it from 3-phase electric motor lines. Main parts such as the motor body, terminal box, and motor shaft are meticulously machined, suitable for installation in various machinery locations with limited space.

The motor has 2 popular mounting styles:

• Foot-mounted (B3) used for fixed placement on a flat surface.
• Flange-mounted (B14/B35) used to mount onto walls, machine frames, or mounting brackets.

Internal structure of the 1-Phase Electric Motor 0.18kW 0.25Hp

Despite its mini size, the internal structure of the 0.18kW 220V motor still includes all basic components:

• Stator: Small-sized electrical engineering steel core, inside which electromagnetic coils (run winding and start winding) made of pure copper with a thin cross-section are wound.
• Rotor: Ultra-small squirrel-cage block, precisely machined and dynamically balanced to prevent vibration when rotating at high speeds.
• Capacitor: Usually uses only a run capacitor to create a phase shift helping the motor start and maintain rotation, as the 0.18kW load level is very light.
• Cooling fan: Mini plastic fan blade attached to the rear shaft, blowing air to cool the aluminum heat sink housing.
• Bearings: Installed at both ends of the shaft, permanently lubricated and fitted with dust covers.

What types of 1-Phase Electric Motor 0.18kW 0.25Hp are available?

The 1-phase 0.18kW 0.25Hp machine series is most commonly applied in two speed ranges:

1-Phase Motor 0.18kW 0.25Hp 2-pole (2,800 – 3,000 rpm)

Applications:

• Mini conveyor belts: Drives ultra-small PVC conveyor sections for sorting electronic components, assembling microchips, or dispensing small cosmetic bottles.
• Small food processing machinery: Installed in poultry roasters, mini chestnut roasting machines, or small-batch spice mixing machines.
• Agricultural and livestock equipment: Used as an automatic egg-turning motor in household-scale incubators, ensuring slow and steady rotational speed.
• Dosing pumps: Supports chemical pump mechanisms and microbial diaphragm pumps that require precise control of pumping flow rates in laboratories.

Which gearboxes can the 1-Phase Electric Motor 0.18kW 0.25Hp be combined with?

With a mini standard shaft diameter of 11mm (up to 14mm in certain flange standards), the 0.18kW 1-phase motor combines perfectly with the following equipment:

• Gearbox: The ultra-small NMRV size 030 series. This combination creates a square, clean, and extremely compact assembly that fits in the palm of your hand.
• Worm gearbox: WPA, WPS, WPX models size 40, designed for environments with mechanical impact.
• Mini helical gearbox: Speed-adjustable mini gearbox series, specialized for compact civilian conveyor belts.

Additionally, it can be combined with:

• Sprockets, small V-belt pulleys (custom-made for 11mm shafts).
• Mini flexible damping shaft couplings.

Guide to wiring a 1-phase electric motor

Supplying power to a 1-phase motor requires precise handling due to the large starting current. You can preview electric motor videos to clearly understand 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 coils and capacitor.

Step 2: Prepare cables and protective devices

Use a 2-core power cable with a cross-section of 4.0mm – 6.0mm. Connect power via a 30A – 40A circuit breaker (MCCB/MCB).

Step 3: Connect 220V power supply

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

Step 4: Operation and rotation direction check

Close the cover, turn on the circuit breaker to test run. If the shaft rotates in the reverse direction of the driven machine, disconnect power and cross-swap the two leads of the run winding (working winding).

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