Abstract
PURPOSE: To reduce a torque unbalance of induction motors due to the difference of radius of curvature of each wheel by a method wherein the output voltage of a smoothing circuit is divided and also, a three-phase inverter circuit is divided corresponded to the divided output to cause the 3-phase power to be supplied from the each 3-phase inverter circuit to the each induction motor.
CONSTITUTION: Filtering capacitors 5a, 5b are connected in series each other to form the inverted L type smoothing circuit G together with a filtering reactor 4 and divide the output voltage. The inverter circuits 7aW7c divided corresponding to the voltage-divided output of the smoothing circuit G are formed, and the divided output of the inverter circuits 7aW7c each is supplied to the induction motors IM1, IM2 each. Thereby, even when the differences arise in the rotation frequency of the individual induction motor due to the difference of radius of curvature of each wheel, the correction of inverter frequencies according to the differences can arrest the differences in a slip frequency.
