DEVICE FOR COMBINED CONTROL OF ELECTRIC DRIVE OF EXCAVATOR SLEWING

摘要

The invention comprises a series-connected sequencer 1, an adder 2, the circuit supply voltage 3 made of serially connected sensor voltage 4 and the regulator voltage 5, a summing magnetic amplifier 6 and generator 7 and motor 8, the elastic element 9 and the turntable 10, current sensor 11, engine speed sensor 12. The sensor 13 and the elastic torque platform velocity sensor 14. All sensors are connected to a torus-regulator 15. The voltage regulator is formed of four integrators 16-19, eight non-inverting amplifiers 20-27 and the two- inverting amplifiers 28-29. 1 yl. I Zh. g - | 5 - 2 5 13 at C
