Title:
回転電機の駆動装置および駆動方法
Document Type and Number:
Japanese Patent JP7181946
Kind Code:
B2
Abstract:
When driving and controlling a plurality of dynamo-electric machines, in order to improve the efficiency of a system that obtains drive force from the plurality of dynamo-electric machines by varying the torque operation amount of each machine in consideration of the temperature dependency of the loss of each dynamo-electric machine, the present invention comprises a plurality of voltage output devices that output a desired voltage to the plurality of dynamo-electric machines, and a control device that adjusts the output voltage of the voltage output devices, the control device acquiring temperature information for each of the plurality of dynamo-electric machines, selecting a dynamo-electric machine having relatively high efficiency from among the plurality of dynamo-electric machines on the basis of the respective temperature information, and relatively increasing a torque command value for the selected dynamo-electric machine in relation to others of the plurality of dynamo-electric machines.
