Title:
DEVICE FOR CONTROLLING TORQUE AND METHOD FOR CONTROLLING THE TORQUE
Document Type and Number:
Japanese Patent JP2004245215
Kind Code:
A
Abstract:
To suppress vibration and noises generated in a low speed rotation zone and secure a wide low speed rotation zone by performing optimum torque control even under a condition that a load of a compressor is low.
A speed control part 20, an inverter output part 22 and a drive circuit 14 controls drive voltage applied to a motor driving a compressor. In parallel, a position detection part 16 and a torque control part 18 estimate a load of the compressor. The torque control part 18 and an output voltage synthesis part 21 regulates drive voltage based on the estimated load and controls fluctuation of rotary acceleration of a rotary mechanism of the compressor.
