Rotor blade set of an electric motor

摘要

A rotor blade set for an electric motor, having a plurality of axially assembled multi-part and/or single-part blades having circle segment shaped blade sections, between which radial and circumferentially open recesses are formed for receiving a respective magnet, wherein a predeterminable number of blade sections of the single-part or multi-part blades have at least one azimuthal clip on the circle radius, which clip bends axially during the insertion of the corresponding magnet into the respective recess, and wherein the circle segment-shaped blade sections of the single-part or multipart blades have at least one notch on the circle radius, in which notch a corresponding clip of a blade section of an axially spaced blade engages following the axial bending.

1. A rotor blade set for an electric motor, the rotor blade set comprising:
a plurality of axially assembled, multi-part and single-part blades having blade sections, including radial and circumferentially open recesses between each blade section, the recesses receiving a plurality of magnets-magnet, wherein each blade section defines a circle sector of the rotor, and wherein at least one blade section of the multi-part blades is only connected to the plurality of magnets; at least one azimuthal clip provided on a circle radius side of a predefinable number of the blade sections of the single-part or multi-part blades, the azimuthal clip being axially bendable during a course of inserting a corresponding magnet into a particular recess; and at least one notch formed on the circle radius side of each blade section of the single-part or multi-part blades, with which a corresponding clip of a blade section of an axially spaced blade engages following the axial bending.
