ABSTRACT:
The present invention refers to an electric motor comprising a stator with an internal permanent magnet and a tubular magnetic return sleeve surrounding said permanent magnet whereby an annular air gap is formed therebetween, said magnetic return sleeve being held at its axial and radial positions relative to said permanent magnet by a frame of plastic material injected around these two components and being connected to said permanent magnet by said plastic frame. The present invention aims at improving the manner in which the two structural components are attached to and positioned on one another. This is achieved on the basis of the features that said plastic frame extends approximately up to the outer circumference of said magnetic return sleeve, and that one end portion of said magnetic return sleeve has provided therein recesses having each at least two edges which extend towards each other in the direction of the interior of the sleeve, the plastic frame being anchored on said magnetic return sleeve by means of said recesses.
