Abstract
A stator arrangement (10) for a radial flux motor (100) having an axis of rotation (100a). The stator arrangement (10) comprises a stator housing (20), a stator (40) and an encapsulation body (50). The stator housing (20) defines a circumferential portion (30) for receiving the stator. The stator (40) is arranged on the circumferential portion (30). Furthermore, the stator (40) is encapsulated in the stator housing (20), wherein the encapsulation body (50) is form-fittingly connected to the stator housing (20) in such a manner that the stator (40) is secured at least in the axial direction (2) in the stator housing (20) by the encapsulation body (50).

A stator arrangement (10) for a radial flux motor (100) having an axis of rotation (100a), comprising:
- a stator housing (20), the stator housing (20) defining a circumferential portion (30) for receiving the stator,
- a stator (40), which is arranged on the circumferential portion (30), and
- an encapsulation body (50),
- wherein the stator (40) is encapsulated in the stator housing (20) and the encapsulation body (50) is form-fittingly connected to the stator housing (20) in such a manner that the stator (40) is secured at least in the axial direction (2) in the stator housing (20) by the encapsulation body (50).
A method (300) for producing a stator arrangement (10) for a radial flux motor (100), comprising the steps of:
- providing (310) a stator housing (20) of a motor housing (110) of the radial flux motor (100), the stator housing (20) defining a circumferential portion (30) for receiving the stator,
- providing (320) a stator (40),
- pushing (330) the stator (40) onto the circumferential portion (30) and placing a bell-shaped encapsulation thereon such that the stator (40) is completely surrounded by the bell-shaped encapsulation and the stator housing (20),
- encapsulating (340) the stator (40) in a horizontal position by filling encapsulation compound between the stator (40) and the stator housing (20) and/or the bell-shaped encapsulation, as a result of which, by curing of the encapsulation compound, an encapsulation body (50) is provided which is form-fittingly connected to the stator housing (20) in such a manner that the stator (40) is secured at least in the axial direction (2) in the stator housing (20) by the encapsulation body (50).
