FIELD: transportation.
SUBSTANCE: invention is related to methods for actuating mechanisms shafts rotation speed control. Device comprises stator, current transmitting device, rotor, controller of pulse width modulation, power switches, frequency synthesizer, reference generator, computer, shunt, voltage-controlled generator, optical couples units with receiver, between which there is a disk with slots arranged with the possibility of rotation, detectors of optical couples.
EFFECT: higher reliability, increased range of transmission ratio control in stepless transmission, improved controllability of variator.
