FIELD: belt conveyers. SUBSTANCE: control unit has starter, electromagnetic shoe brake and speed sensor mounted for direct contact with conveyer belt. One end of electromagnetic brake winding is connected to one phase of starter contactor on input side, second end is connected to second phase on output side and to the same phase through make contact of speed sensor on input side. Unit provides for braking electric drive at the moment, when speed of conveyer belt movement is nearly zero, thus preventing slipping of belt on drive drum due to its inertia movement, when electric drive is braked. EFFECT: excluded belt abrasive wear. 1 dwg
