  • Patent number: 11108314
    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.
