METHOD FOR BRAKING A COMPRESSOR AND COMPRESSOR OF A REFRIGERATION DEVICE, OF AN AIR CONDITIONING DEVICE, OR OF A HEAT PUMP, AND REFRIGERATION DEVICE, AIR CONDITIONING DEVICE, OR HEAT PUMP HAVING SAID COMPRESSOR

摘要

The invention relates to a method for braking a compressor of a refrigeration device, of an air conditioning device, or of a heat pump, wherein the compressor comprises a brushless motor (100) having windings (130U, 130V, 130W) and comprises a controller (160) for braking the motor. According to the invention, the controller (160) is designed to brake (306) the brushless motor (100) by means of a braking current in a controlled manner starting from an operating rotational speed (302), wherein the braking current during the controlled braking is dependent on induced voltages determined before the controlled braking. The method for braking contains the following steps: a) rotating (201) the motor at an operating rotational speed; b) receiving (202) a signal for braking; c) determining (203) voltages induced in the windings; d) supplying (204) a braking current having a decreasing frequency to the windings, wherein the braking current during the braking is dependent on the previously determined induced voltages.
