Excavator electric motors of the DE series (DEV) from the Belgorod Electrotechnical Plant, they are designed to operate in long-term, short-term and repeated-short-term loads. The winding is available in three types of electrical design, respectively, the following methods of motor excitation are available: independent, serial and parallel. High-level insulation, suitable modifications for temperate, cold and tropical climates are presented.
Robust construction on legs with conical ends of one or two shafts or without legs with flange mounting and vertical shaft position (two ends). The engine is blown forcibly or cooled by natural heat exchange. Both versions can be easily transformed relative to each other.
