- four rotor magnets are provided, which are mounted in a rotor housing so that the inner peripheral surfaces of the
- Rotor magnets lie exactly opposite an outer circumferential surface of the stator core.
- Rotor housing can only be done with limited accuracy. This has an unfavorable effect on the operating behavior of the known electric motor.
- the rotor is composed of one or more disk packs or individual laminations and other components.
- the lamellae or disk packs can be pushed axially onto a shaft, so that they immediately adjoin one another.
- the individual disks for example a disk set, can be produced by stamping, wherein the individual disks can be packaged after punching to form a disk package.
- punching also recesses can be achieved, which add to the disk pack to pockets in which magnets are present in the mounted state of the rotor, that is buried.

- the electric machine according to the invention with the features of claim 1 has the advantage that a reliable and relatively inexpensive to betechnikstelligende positioning of the magnets in the rotor is made possible. Specifically, an accurate tangential positioning of the magnets can be done relative to the disk packs to reduce a cogging torque of the electric machine.
- the electric machine has at least two magnets. Of the magnets of the electric machine at least one is arranged in a recess according to claim 1.
- the resilient projection of the blade is biased for at least indirect attachment of the magnet in the recess in a tangential direction.
- the lamella can be designed so that an elastic deformation of the resilient approach is required for introducing the magnet into the recess.
- an attachment of the magnet is achieved in the recess, which is already sufficient, depending on the particular application, to the magnet to fix. Separate fasteners, the use of adhesives or the like, is then not required.
- a defined position of the magnet in the radial direction can be specified by the bias in the tangential direction.
- the resilient lug for biasing the magnet in the recess is biased in a radial direction.
- an attachment of the magnet in the recess can be achieved, which does not require the additional use of fasteners or adhesives depending on the particular application.

This ensures that accumulate the holding forces of the resilient lugs, whereby a reliable attachment is achieved even at relatively high loads. Furthermore, it is advantageous that an intermediate space is provided between one, two or even a plurality of resilient projections arranged one behind the other. Through the gap a certain bending of the resilient projections when inserting the magnet is made possible in the recess. This facilitates the mounting of the magnet in the recess. In addition, thereby the resilient lugs can be configured so that they protrude relatively far into the space required by the magnet to be inserted, whereby already one of the resilient lugs exerts a relatively large holding force.
