Abstract
A compressor of a refrigeration appliance includes a motor, in particular a BLDC motor, and a controller for stopping the motor. The controller is configured to slow down the motor rotating in a first rotating direction until it comes to a standstill and to subsequently position the rotor relative to the stator, in a second rotating direction with a predetermined torque. A method for stopping a compressor of a refrigeration appliance is also provided.

1-15. (canceled)
A method for stopping a compressor of a refrigeration appliance, the method comprising the following steps:
- providing a compressor motor including a cylinder, a piston operating in the cylinder, a piston rod, a rotor and a rotor shaft connecting the rotor to the piston rod;
- a) slowing down the motor rotating in a first rotation direction until the motor stops;
- b) positioning the motor in a second rotation direction (208, 209) with a predefined torque;
- and
- c) terminating the positioning.
A compressor of a refrigeration appliance, the compressor comprising:
- a motor including a stator, a rotor having a rotor shaft, a cylinder being fixedly positioned relative to said stator, a piston being movable in said cylinder and a piston rod connecting said piston to said rotor shaft;
- and
- a controller for stopping and activating said motor, said controller being configured to slow down said motor rotating in a first rotation direction until said motor stops, and to then position said rotor in a second rotation direction (208, 209) relative to said stator with a predefined torque.
