DC electric motors for excavators of the DPE, DPV series (mechanisms of stroke, pressure, opening and turning of the bucket) and for drilling rigs of the DPB series They are designed to work in long cycles without interruptions, in short-term, repetitive modes. Excitation of an independent or mixed type.
Horizontal on the legs and vertical mounting design, three levels of protection of the housing from dust and moisture penetration. There are also three types of cooling system: self-ventilation with an impeller mounted on a shaft (only in constant operation), blowing through a nozzle from an external air supply device or natural heat exchange with the environment.
