Method and apparatus for controlling a scroll compressor using torque progression to reduce vibration
Abstract:
The invention relates to a method used to control a scroll compressor having a first and a second spiral, in particular that are arranged one inside the other. The first spiral can be moved by a motor relative to the second spiral for a decompression or compression operation of the scroll compressor. The invention reduces vibration (actual acceleration forces) in the scroll compressor to allow for a longer service life by adapting a torque curve of the motor on the basis of measured acceleration forces on the scroll compressor which, in turn, is based on the position and/or positional angle of the first spiral relative to the second spiral such that the acceleration forces are reduced below a threshold or minimized.
