Helmke high-voltage asynchronous motors with a closed-loop rotor of the DOR series from a German manufacturer, manufactured using modern technologies, they are characterized by a high level of efficiency and energy efficiency (IE2 and IE3 classes). Such working qualities allow you to get the most out of the production cycle and save on the resources involved. A wide range of standard sizes of this series is always maintained in stock. Both horizontal and vertical installation is possible.
Robust cast-iron housing construction, reliable support bearings for stable and safe operation of powerful electrical equipment. The squirrel cage type rotor windings are made of aluminum or copper. The end winding is covered with an insulating layer according to VPI technology (vacuum impregnation). Cooling by self-ventilation using the built-in radial fan on the motor shaft.
Typical areas of use of this type of electrical equipment: compressors, crushers, mills, pumps, fans, blowers.
