<p>PURPOSE:To prevent a slipping from occurring by providing controllers in a plurality of trucks, and providing load detectors thereat. CONSTITUTION:A controller 9 provided in a motor drive vehicle M has a pair of control units capable of accelerating or decelerating a motor 5 at an every truck 4 unit. A power drive notch command, a shaft load signal from a truck load detector 7 and a current signal detected by a current detector CT are input to the accelerating current setter of each control unit to control a variable voltage variable frequency (VVVF) inverter with the calculated result. Thus, since the amplitude of the accelerating current is set by the magnitude of the truck loads of preceding and trailing trucks 4A, 4B, it can prevent them from slipping.</p> |
