Abstract
PURPOSE: To increase re-adhesion characteristics at the time of traction-wheel slipping, by providing a plurality of rectifiers which operates commonly to a plurality of motors, and a plurality of rectifiers which control individual motors separately.
CONSTITUTION: One bridge-rectifier circuit in a rectifier assembly 2 wherein four single-phase bridge rectifiers are connected in 4 stages is divided into 4 rectifier circuits 211W214 in parallel, and the dc output terminals of the rectifiers 211W214 are connected to 4 motors 31W34. When a traction-wheel slips, the torque of the slipping motor can be reduced without giving an impact on the torque of the motors which are not slipping, by squeezing the phase of the rectifier circuit corresponding to the motor shaft of the slipping motor so as to reduce the motor current which is driving the slipping wheel.
