Electric Motors — Industrial Asynchronous Motors for Automation

Asynchronous electric motors are the primary drive for industrial equipment: pumps, fans, compressors, conveyors, and machine tools. Our catalog features 830+ models ranging from 0.25 to 450 kW from leading manufacturers: ABB, WEG, AIR, Siemens, Bosch Rexroth, and Lenze. Three-phase 380V motors with IE2–IE4 energy efficiency classes for any industrial application.

How to Choose an Electric Motor

When selecting a motor, consider power rating, rotational speed, supply voltage, energy efficiency class (IE), and IP protection rating. For operation with a variable frequency drive, choose motors with reinforced winding insulation.

Frequently Asked Questions

How to choose an electric motor by power rating?

Motor power is determined by the equipment load. For pumps and fans, a motor matching the mechanism's nominal power is sufficient. For heavy-duty starts (compressors, crushers), add a 15–20% margin. Main ranges in the catalog: 0.25–3 kW (light-duty), 5.5–30 kW (industrial), 45–450 kW (heavy-duty applications).

What is the difference between IE2, IE3, and IE4 efficiency classes?

IE class defines motor efficiency at nominal load. IE2 (High Efficiency) is the basic industrial standard. IE3 (Premium Efficiency) offers 1–2% higher efficiency, paying for itself in 1–3 years. IE4 (Super Premium) provides maximum efficiency, recommended for 24/7 operation. ABB and WEG motors are available in IE2–IE4 classes.

Can I connect an electric motor to a VFD?

Yes, all asynchronous motors in our catalog work with variable frequency drives (VFDs). For prolonged operation at low speeds, we recommend motors with reinforced winding insulation and forced ventilation. ABB M3AA and WEG W22 series are specifically optimized for inverter-duty operation.

Which motor to choose: ABB, WEG, or AIR?

ABB is the premium segment with the highest reliability and efficiency (IE2–IE4), ideal for critical equipment. WEG offers the best price-to-quality ratio with IE2–IE5 range. AIR is a budget solution for general industrial tasks where IE2 suffices. The choice depends on your budget and operating mode.

How to determine electric motor rotation speed?

Speed depends on the number of poles: 2 poles — 3000 RPM, 4 poles — 1500 RPM, 6 poles — 1000 RPM, 8 poles — 750 RPM (at 50 Hz grid frequency). Actual asynchronous motor speed is 2–5% less (slip). For precise speed control, use a variable frequency drive.
