Three-phase electric motors VEM K21B /K23B Series an open-type water cooling system is used, an especially durable grey cast iron structure with low vibration characteristics, the most compact dimensions, high efficiency and environmentally friendly operation of the heat removal unit. This type of electrical equipment is very popular in the fields of mechanical engineering (injection molding), when working with extruders, printing presses, in paper production, mining and development technologies.
VEM electric motors are distinguished by high power without unnecessary bulkiness of design, the absence of additional inconveniences associated with increased noise and vibration factors, the release of a minimum amount of heat into the environment that does not require special measures and the ease of integration into the production cycle of water supply. Bearings from the world's best manufacturers with a service life of up to 40,000 hours are installed. Additional sensors for monitoring and protection against thermal overload, other accessories, structural blocks and modifications for better adaptation and optimization of equipment operation can also be installed on request
