Hi,

this is quite a tough job.

Japanese owned PMDM is one of the manufacturers of these motors for HDDs.

They have a development unit of 100+ employees in Germany that are developing and doing sample production of bearings and motors.

So if you want to enter this field - ask for a license.

If you want only a few of these motors get old HDDs.

If you want to do something else it may be advisable to rethink the principles.
