Abstract
The invention relates to an electrical machine having a rotor (1), a stator (2) radially surrounding the rotor, and a housing (4) radially surrounding the stator. In order to minimize stresses in the housing and nonetheless decrease the tendency of the stator to torsional vibrations, the stator is connected to the housing at least at one end in a radially and torsionally rigid but axially movable manner, for example, by way of an axially compliant material area. The electrical machine can, in particular, be a motor spindle in a gear finishing machine.
Claims24
An electrical machine, comprising:
- a rotor that is rotatably supported around an axis of rotation and defines an axial direction with its axis of rotation;
- a stator radially surrounding the rotor, the stator having a distal end and a proximal end;
- and
- a housing radially surrounding the stator,
- wherein the stator, at at least one of its distal end and its proximal end, is connected to the housing by a connection that is radially and torsionally stiff while facilitating axial movability of said at least one of its distal end and its proximal end relative to the housing.
