Sweg Motor


We specialize in high-quality energy-efficient electric motors. The combination of the best available materials, high-quality sheet metal, and the right amount of copper in the rotor/stator makes our electric motors highly energy-efficient.
We design our electric motors to fit and match specific requirements. These motors can be supplemented with a range of options and accessories or modified with special designs to endure any environment.
Electric motors account for a large part of industrial electricity use. To reduce consumption, there are legal requirements regarding the efficiency of electric motors manufactured or exported into the EU. Three-phase, single-speed asynchronous motors are the most common, accounting for 90 percent of the electricity consumption in the power range of 0.75 - 375 kW.
According to international standards, energy efficiency classes are designated as IE1, IE2, IE3, and IE4, where IE4 represents the highest efficiency level.
From July 1, 2021: 2-, 4-, 6- and 8-pole motors from 0.75 - 1000 kW are included in efficiency class IE3. Motors within the range 0.12 - 0.75 kW must meet efficiency class IE2.
From July 1, 2023: For 2-, 4-, 6- and 8-pole motors from 0.12 - 1000 kW, efficiency class IE2 also applies to Ex eb certified motors. Higher efficiency class IE4 applies to 2, 4 and 6-pole motors between 75 - 200 kW.
