WEG Electric Motors — Brazilian quality for industrial drives

WEG is one of the world's largest electric motor manufacturers. The Chastotnik.ua catalog features over 200 WEG three-phase asynchronous motor models ranging from 0.12 to 400 kW. The W22 series complies with IEC international standards and delivers an optimal balance of performance and cost. For speed control of WEG motors, we recommend VFDs for electric motors, and for soft starting — soft starters. Browse the full motor range in the electric motors section.

How to choose a WEG electric motor

When selecting a WEG motor, consider the driven load power, synchronous speed (determined by pole count), rated current, and operating conditions. For pumps and fans, a 10-15% power margin is sufficient; for conveyors and crushers — 20-30%. All WEG motors feature IP55 protection — full dust and water spray ingress protection.

To match a VFD to your WEG motor, visit the frequency converters section — VFD power must equal or exceed the motor rating.

Electric motor manufacturers

The Chastotnik.ua catalog features industrial electric motors from leading global and domestic manufacturers:

  • WEG — Brazilian manufacturer, W22 series, 202 models in catalog, optimal price-to-quality ratio
  • ABB Electric Motors — Finnish premium class, IE3 efficiency, 381 models
  • AIR Electric Motors — domestic production per DSTU standard, 121 models, most affordable pricing

WEG motors by specifications

Select WEG motors by key technical parameters:

  • By power: from 0.12 kW (small mechanism drives) to 400 kW (heavy industry)
  • By speed: 500, 600, 750, 1000, 1500, 3000 rpm
  • Supply voltage: 220/380 V — star or delta connection
  • Protection rating: IP55 — for dusty and humid industrial environments

For WEG motor speed control, select the appropriate VFD for electric motors. For instance, a WEG 5.5 kW motor pairs with a 5.5 kW VFD, and an 11 kW motor with an 11 kW VFD.

Warranty and support

All WEG electric motors come with 12-month manufacturer warranty. Shipping across Ukraine: Nova Poshta, Delivery, warehouse pickup. Payment: bank transfer (VAT included), cash on delivery. Free technical consultations on motor and VFD selection.

Frequently Asked Questions

How do WEG electric motors compare to ABB and AIR?

WEG (Brazil) offers the best price-to-quality ratio with the W22 series meeting IEC standards and IP55 protection. ABB (Finland) is the premium segment with IE3 efficiency class, priced 30-50% higher. AIR motors are domestically produced to DSTU standards with the lowest prices but a narrower power range.

Which VFD is compatible with a WEG motor?

The VFD power rating must equal or exceed the WEG motor power. For 220/380 V motors, use three-phase 380 V VFDs. For example, a WEG 5.5 kW motor needs a 5.5 kW VFD, and a WEG 11 kW motor needs an 11 kW VFD. Recommended brands: Veichi, Delta, Danfoss.

What is the maximum power of WEG motors in the catalog?

The Chastotnik.ua catalog features WEG motors from 0.12 kW to 400 kW. Speed range: 500 to 3000 rpm (12 to 2 poles). All models feature 220/380 V supply voltage and IP55 protection rating.

How to connect a WEG motor — star or delta?

At 380 V mains, connect the WEG 220/380 V motor in star (Y) configuration — 380 V between phases at terminals. At 220 V — use delta (Δ). When using a VFD with 3x220 V output, connect in delta. The connection diagram is shown on the motor nameplate.

What IP protection rating do WEG motors have?

All WEG motors in the catalog have IP55 protection — full dust protection and water spray ingress protection from any direction. This is sufficient for 95% of industrial applications: workshops, pump stations, ventilation rooms. For aggressive environments or outdoor installations, contact us for consultation.
