Low-voltage asynchronous motors VEM Motors with a closed-loop rotor series WE1R, WE2R, W21R, W22R they are made according to the IEC standard and have an energy efficiency class IE2 (high) with improved performance and increased efficiency for more economical, productive and comfortable operation. Moreover, the energy-saving mode is implemented not only at full load, but also at partial load.
Ribbed housing made of high-strength grey cast iron with low vibration index, a wide range of standard sizes and mounting options. The engine is cooled by self-ventilation from a radial fan mounted on the shaft blowing over the outer surface. Designed to work with a frequency converter. High degree of protection against moisture and dust penetration.
A wide range of additional extensions, modifications and accessories are available.
