Abstract
A refrigerant compressor is disclosed, having an electric motor, the stator of which has windings with winding heads and the rotor of which drives a compressor which comprises a compressor lock having an axially projecting bearing part for a rotor shaft, one winding head extending in the direction of the compressor block and electrical insulation being provided between the winding head and the compressor block. With the same overall size, it is desirable to be able to improve the efficiency of such a refrigerant compressor without markedly increasing the effort involved in assembly. To that end, the insulation is formed by a film which is pushed with a substantially centrally arranged opening onto the bearing part.
