Are there any more specific details about the magnet that comes attached to this motor? I am looking for material, strength, and dimensions.

The datasheet currently only shows the OD.

We just know what’s provided in the datasheet :-/

Sometimes you can have luck by contacting the manufacturer directly and asking [https://oncetopmotor.goldsupplier.com/](https://oncetopmotor.goldsupplier.com/)
