1. A method for controlling a scroll compressor having first and second spirals arranged one inside the other, wherein the first spiral moves by operation of a motor relative to the second spiral for one of a decompression or compression operation of the scroll compressor, comprising:
operating the motor to move the first spiral;
measuring a plurality of acceleration forces on the scroll compressor, wherein the acceleration forces depend on one of a relative position or a positional angle of the first spiral to the second spiral; and
adjusting a torque progression of the motor based on the measured acceleration forces to reduce actual acceleration forces on the motor until a change in a decrease of the acceleration forces reaches a predetermined value, wherein a torque supplied by the motor is shifted as a function of an angle or a phase, or of a positional angle of the second spiral relative to the first spiral.
