Abstract
An electric machine has a stator and a rotor. The rotor is arranged on a rotor shaft that can be rotated about an axis of rotation. The stator surrounds the rotor radially on the outside with respect to the axis of rotation. The stator is surrounded radially on the outside by a one-piece housing with respect to the axis of rotation. As viewed around the axis of rotation, the housing extends only over a partial angular range. As viewed around the axis of rotation, a remaining angular range, in which the stator is not surrounded by the housing, thus remains. In end regions located at the ends of the partial angular range, the housing has housing-side form-closure elements, which cause a form closure of the housing with the stator in interaction with stator-side form-closure elements.
Claims8
An electrical machine, comprising:
- a rotor disposed on a rotor shaft for rotation about an axis of rotation;
- a stator, in relation to the axis of rotation, surrounding the rotor radially to the outside, and having form-fit elements;
- and
- a one-piece housing radially surrounding the stator in relation to the axis of rotation to the outside, said housing sized to extend only over a part angular area, viewed about the axis of rotation, so as to leave a remaining angular area in which the stator is not surrounded by the housing, said housing having form-fit elements in end regions at ends of the part angular area, said form-fit elements of the housing interacting with the form-fit elements of the stator to establish a form-fit between the housing and the stator.
