FIELD: electrical and mechanical engineering. SUBSTANCE: drive has traction electromagnet 1 which mobile part 3 is connected with working mechanism 4. Magnet fixed part has winding 5 which electrical circuit includes position pick-up unit made like choke coil 11 bridged by diode 13. Choke coil and diode circuit has sensitive element of position pick-up of mobile part of traction magnet. Winding 5 is connected to power supply by base and supplementary switching devices. Control input of supplementary device is connected to sensitive element of displacement pick-up. EFFECT: more simpler construction of powerful electrical actuators. 2 dwg |
