摘要： Method for stopping a hermetically encapsulated refrigerant compressor (1) having a hermetically sealed housing (7), arranged therein a reciprocating piston/cylinder unit (2) which comprises a crankshaft (3), and an electric motor (4) which drives the crankshaft (3), and a control unit (5) which controls the electric motor (4), wherein the control unit (5) operates the electric motor (4) if an operating signal, preferably a frequency signal, is present, and detects the termination of the operating signal. It is provided that, after the detection of the termination of the operating signal, a rotational speed (V) of the crankshaft (3) is reduced by means of the electric motor (4) with a reduction rate over a time duration (I), wherein the time duration (I) is determined in a manner which is dependent on the last operating signal before it is terminated.
