Technical Examples

The driving apparatus according to the invention includes an inverter that drives multiple induction motors connected in parallel, and a secondary current calculating circuit that calculates the components i2W and i2L of a total secondary current value, which is the sum of the secondary currents of all the motors. The apparatus further includes a current deviation quantity calculating circuit that calculates a deviation quantity, for which the total secondary current value deviates from a reference trace. A torque regulating circuit regulates the motor torque based on the calculated deviation quantity. The driving apparatus for driving multiple induction motors according to the invention facilitates quickly detecting the widening caused in the rotating speed differences and preventing the rotating speed differences from widening.
