Abstract

The invention discloses a method, device and compressor for compensating torque, and relates to the field of control. The device for compensating torque is used for detecting work parameters of a compressor rotor by a preset cycle, determining the current resistance torque characteristic curve of the compressor according to the detection result, and performing corresponding torque compensation for the compressor according to the comparison result of the current resistance torque characteristic curve of the compressor and a preset resistance torque curve. According to the device, the current resistance torque characteristic curve of the compressor is compared with the preset resistance torque curve, and corresponding torque compensation is carried out for the compressor according to the comparison result, so that the vibration and noise of the compressor can be effectively reduced.

Description

technical field [0001] The invention relates to the field of control, in particular to a torque compensation method, device and compressor. Background technique [0002] For air-conditioning compressors, due to the large difference in resistance torque between suction and discharge in the compression chamber, the compressor will vibrate during operation, especially at low frequencies. Strong vibration will cause noise and other problems, and in severe cases, it will cause the pipeline of the air conditioning unit to break, affecting the reliability of the unit. [0003] The conventional torque compensation method is to perform feed-forward compensation according to the characteristics of the compressor resistance torque, but the resistance torque of the compressor is different under different working conditions and speeds, and the preset resistance torque curve cannot meet the requirements of the changing working conditions. In order to overcome this defect, there is also a...
