MAGNET HOLDER, SENSOR MAGNET ASSEMBLY, ELECTRIC MOTOR COMPRISING A SENSOR MAGNET ASSEMBLY, AND METHOD FOR PRODUCING A SENSOR MAGNET ASSEMBLY
First Claim
1. A magnet holder for attaching a sensor magnet to a motor shaft of an electric motor, the magnet holder comprising:
- a receiving recess for receiving the sensor magnet;
an attachment region for attachment to the motor shaft;
the receiving recess being radially delineated by a wall having a circumference;
a plurality of weak spots over the circumference of the wall;
the weak spots having a reduced wall thickness and being designed in such a way that free spaces remain between the weak spots and the sensor magnet when the sensor magnet is arranged in the receiving recess; and
the sensor magnet being held in the receiving recess in a form-locked manner on both sides of the weak spots by wall regions having a larger wall thickness.

Abstract
A magnet holder for attaching a sensor magnet to a motor shaft of an electric motor, including a receiving recess for the sensor magnet and an attachment region for attachment to the motor shaft, wherein the receiving recess is radially delimited by a wall that, over the circumference thereof, includes a plurality of weak spots which have a reduced wall thickness and are designed so that free spaces remain between the weak spots and the sensor magnet arranged in the receiving recess. The invention further relates to a sensor magnet assembly, to an electric motor comprising a sensor magnet assembly, and to a method for producing a sensor magnet assembly. It is the object of the present invention to very reliably and durably attach a sensor magnet to the end of a motor shaft in a very economical and simple manner, wherein adhesive methods are to be dispensed with.
