Definitions
- the present invention relates to an electric motor, the electric motor comprising at least one stator and one rotor.
- the electric motor is an axial flux motor (AFM).
- Electric motors generate heat during operation. If this heat is not sufficiently dissipated, the electric motor heats up, which can reduce efficiency.
- an electric motor is to be specified which is of compact construction and which has an efficient cooling device.
- An electric motor is proposed, at least having one
- a rotor with at least one (preferably a plurality of) magnets and an axis of rotation and an outer peripheral surface.
- the stator and the rotor are arranged side by side along the axis of rotation.
- the rotor has a fluid guide structure between the axis of rotation and the outer peripheral surface.
- the fluid guide structure has at least one surface which extends at least in a radial direction and is at least embodied at an angle to the circumferential direction or to an axial direction parallel to the axis of rotation (or to a plane arranged perpendicular to the axis of rotation).
- a fluid flow conveyed by the fluid guide structure during operation of the motor can be conducted at least partially via the coils within the housing.
- the rotor of the motor drive a fluid circuit, that is to say generate a fluid flow within the housing, which can be used to dissipate heat generated by the motor.

- the rotor has, in particular, permanent magnets and / or soft magnetic elements, for example in cutouts.
- a permanent magnet synchronous or brushless DC motor, abbreviated BLDC can preferably be formed with permanent magnets, while a reluctance motor can be created as an electric motor, for example with soft magnetic elements.

- the fluid guide structure and the at least one surface are formed by the one magnet or by at least one (in particular by the total number) of the magnets.
- the at least one magnet or at least one of the magnets has a geometry by which the fluid guide structure is formed. The geometry of the magnet thus has at least one surface which extends at least in a radial direction and is at least designed to be inclined with respect to the circumferential direction or an axial direction parallel to the axis of rotation.

- a fluid flow can be sucked in via the rotor, in particular starting from the axis of rotation, and conveyed outward via the rotor in the radial direction.
- a fluid flow can start from the external Ren circumferential surface sucked and conveyed inward in the radial direction via the rotor.
- the fluid guide structure is designed in such a way that at least 1%, preferably at least 5%, particularly preferably at least 10% or at least 20% of a current drive power of the motor for conveying the fluid flow is required.
- the fluid guide structure is designed in such a way that at least 1%, preferably at least 5%, particularly preferably at least 10% or at least 20% of a nominal output of the motor is required to convey the fluid flow.
- the current drive power can be determined from the current operating parameters of electrical current and electrical voltage.
- the drive power of the motor required to convey the fluid flow can be determined in particular in a test facility.
- the parameter “the drive power required to convey the fluid flow” can be used in particular to describe the execution of the fluid guide structure.
