I have a question regarding the installation of the above-mentioned magnets. I could not find any installation recommendations in the data sheet. I also could not find any tolerances in the technical drawing. What is the best way to mount the magnets? In our application, we want to attach the magnets to a rotating shaft in order to measure the angle using a Hall sensor.
Are they pressed into a hole using their outer diameter ? What fit do you recommend for the hole? Is it also possible to glue the magnets?
Thank you for the support.
Kind regards

Hello Marc,
I do not recommend press fitting the magnets. I recommend epoxying the magnet inside of an adapter piece. The other end of this adapter can be either press fit or also epoxied onto the end of your shaft. Make sure this adapter is not ferrous so that it does not interfere with the magnetics.
Best regards,

Hello Kerr,
Thanks for the quick reply.
We are now thinking about gluing the magnet directly into our shaft. The shaft is made of stainless steel and is not magnetic. As far as I know, stainless steel is a ferrous material, but not magnetic. Do you think that this could have a negative effect on the properties of the magnet?
Kind regards
Marc
Marc,
Most stainless steels are not magnetic. I should have been more specific and clarified that you should try to avoid ferromagnetic materials not necessarily ferrous.
As for gluing the magnet on the end of the shaft, make sure that alignment is maintained and that the glue can hold at the max RPM. In my personal projects I have used 3d printed pieces to hold the magnet in place while the epoxy cures with pretty good success.
Please let me know if you have any more questions or concerns.
Best,
-Kerr
