Abstract: The present disclosure relates to a laundry treatment machine. The laundry treatment machine according to an embodiment of the present disclosure includes a controller configured to start dewatering after a first period from completion of drainage when a lift is at a first level, and to start the dewatering after a second period from the completion of the drainage when the lift is at a second level greater than the first level, wherein the second period is longer than the first period. Accordingly, based on the lift, it is possible to change the dewatering entry period after drainage is completed.

Abstract: The present disclosure relates to a laundry treatment machine and a method for controlling the same. An increased amount of wash water during dewatering is introduced into a pump by decreasing the speed of a pump motor provided in the pump and increasing it again based on changes in the speed of the main motor during dewatering, and the wash water introduced while the speed of the pump motor is increasing is drained. Thus, the amount of noise generated during drainage may be reduced, drainage performance may be improved, and drainage time may be shortened.

Abstract: A compressor is provided. The compressor according to the present disclosure includes: one or more impellers suctioning and compressing refrigerant; a motor rotating the impeller; a rotation shaft to which the impeller and the motor are connected; a gap sensor measuring a displacement change of the rotation shaft as a frequency change; a temperature compensation sensor determining a frequency compensation value according to a temperature change around the gap sensor; and a control unit calculating a displacement amount of the rotation shaft by reflecting the frequency compensation value provided by the temperature compensation sensor and the frequency change measured by the gap sensor.
