Title:
MOTOR COMPRESSOR
Document Type and Number:
Japanese Patent JP2017044206
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a motor compressor capable of suppressing the occurrence of a reverse re-rotation phenomenon while suppressing noise and vibration.SOLUTION: A motor compressor 10 includes an electric motor 16 having a rotor 51, a housing 11 formed with a suction port 11a from which refrigerant is sucked, and a compression part 15 for compressing the sucked refrigerant sucked from the suction port 11a and discharging the compressed refrigerant. The motor compressor 10 further includes an injection port 43 for introducing intermediate pressure refrigerant having a pressure higher than the sucked refrigerant and lower than the compressed refrigerant into a compression chamber 33, an invertor 55 for driving the electric motor 16, and a control device 60 for controlling the invertor 55. The control device 60 performs speed reduction control to reduce the speed of the rotor 51 on the basis of the rotation of the rotor 51 in the direction opposite to the normal direction, and then performs continuation control to continue the rotation of the rotor 51.SELECTED DRAWING: Figure 1
