Abstract

The device is applied in electro-starts of crane and other mechanisms. It has a high cos PHI and an even thermal charge of the magnetic conductors' elements, which reduces the expenditure of active materials. The device consists of three equal inductional systems, each of which contains concentrically internal (1) and external (2) ferrous-magnetic pipe, to the edges of which ferrous-magnetic plastics (3) are placed for the radial closure of the magnetic circuit. Between the internal (1) and external (2) tubes, a coil (4) and an axially ventilation channel (5) are located. The internal tube (1) are attached ferrous magnetic bodies (6), magnetically connected with the edges of the pipes (1 and 2) and surrounded by ventilation channels (7 and 8), which are in free touch with environment.
