Recently WEG updated its portfolio of standard industrial motors with the W40, W50 and W60 motors series. The motors collectively cover the power range from 90 to 4,250 kW at frequencies of 50 and 60 Hz. The three-phase induction motors are suitable for nearly all industrial applications requiring high performance and reliability, including pumps, compressors and fans. The design has been optimised to make the motors more compact than their predecessors, with lower weight, smaller dimensions and a reduced footprint. With grey cast iron housings, they are suitable for use under adverse conditions and assure low noise and vibration levels. Optimised rotor and stator laminations together with improved motor cooling give a high power density (ratio of output power to weight)..
The two-pole and four-pole motors in the W60 series are available in frame sizes from IEC450 to IEC560, with rated power from 800 to 4,250 kW and rated voltage from 2,300 to 10,000 V. To maximise application flexibility, the motors are available in three configurations: open and self-ventilated (IC01, WP-II), closed and air/air-cooled (IC611, TEAAC) and closed with air/water heat exchanger (IC81, TEWAC). Thanks to their compact design, the motors have a smaller footprint and are the shortest modular motors of their sort on the market. Noise and vibration levels are especially low thanks to sturdy construction with a high-quality grey cast iron frame and shield as well as a true stiff motor shaft that eliminates critical flexural vibrations below the rated speed. This makes the W60 motors a good choice for applications with frequency inverter operation or strong shaking loads.
