WEG.WEG is a manufacturer of motors, automation, and energy equipment. The WEG W21 series motor employs advanced wide-frequency and wide-voltage design, enabling standard motors to achieve constant torque from 25 to 75 Hz and constant power from 75 to 100 Hz. Both the motor body and terminal box are constructed from FC-200 ductile iron. Insulation approaches Class H, with efficiency reaching IE3 (IE4 for W22 models). The W21 aluminum-housed motor is available up to frame size 200. As a benchmark for high-efficiency energy-saving motors, WEG entered the Chinese market in 2005. Its superior products, imported materials, and globally backed warranty service rapidly captured market share domestically. Applications span mining machinery, chemical processing, fans, pumps, and related industries. We hope more users will choose cost-effective products. Key features of WEG motors: WEG motors utilize 200°C temperature-resistant enameled wire, with stator and rotor cores made from cold-rolled silicon steel sheets. The double-vacuum impregnation process ensures uniform coating coverage on both surfaces and within the sheet gaps, eliminating fine bubbles. This prevents excessive air gap resistance, effectively reducing temperature rise and enhancing motor efficiency. Furthermore, the use of imported SKF, FAG, or NSK bearings significantly extends the overall operational lifespan of the motor while ensuring safe operation. Primary products include: motors, frequency converters, induction motors, synchronous motors, medium- and high-voltage motors, and cooling tower motors.
