We present to your attention crane and metallurgical DC electric motors from the Russian manufacturer, a wide range of models of the D series. These are high-performance motors with dimensions of the axis of rotation from 160 and over 340 mm, used mainly for operation in electric drive systems of various lifting and transport equipment, the metallurgical industry, conveyor mechanisms. Operating modes S1 (without interruption), S2 (short-term) and S3 (repeated-short-term).
The range includes versions with different types of excitation (sequential, independent, mixed), the design, depending on the intended operating mode, can be with a closed housing without special cooling devices or with an installed fan (independent power supply). The design can be protected or closed (from the penetration of dust and moisture), with forced and natural cooling, high-speed and low-speed options. According to environmental conditions, the engines of this series have a specification for temperate, cold and tropical climates.
