ATEX geared motors

“With this ATEX certification, we can now offer WG20 geared motors for applications in explosion hazard areas, such as oil and gas, chemical or food industry,” comments René Binder, sales manager of WEG subsidiary, Watt Drive. “The geared motors are compact and available with energy efficiency ratings up to IE3, making them very cost-effective. Investments in energy-efficient drives generally have relatively short payback times.”

Explosion-proof WG20 geared motors are currently available with rated output power from 120 to 30kW. They are designed for voltages to 690V, in frame sizes from IEC 63 to IEC 200. With the ongoing expansion of the WG20 series of geared motors to 18,000Nm, explosion-proof geared motors for the entire power range up to 75kW will be available soon. All these ATEX geared motors can be built with protection rating to IP66 and are suitable for an ambient temperature range of -20 to +40°C. The motors can also be operated with variable speed drives, subject to compliance with the specified driver parameters. The range of accessory modules, such as explosion-proof brakes and encoders, is constantly expanding.
