Japanese Patent JP3525397
Kind Code:
B2
Abstract:
PURPOSE: To attain safety driving by preventing the occurrence of the slip, etc., of a travelling car driven in a multi-spindle while balancing the load of each shaft.
CONSTITUTION: When a controller 1A controlling the speed of a motor 2A and a controller 1B controlling the torque of a motor 2B are mounted and a travelling car is driven in a multi-spindle at every shaft or at every wheel, a value obtained by multiplying an output from a pulse encoder 3B by k1 by a multiplier 16 is selected by a selector 15 when slip occurs to the motor 2B side, the value is used as a speed detecting value, and speed is controlled by a speed regulator 11A, thus inhibiting the slip of the motor 2B.
