ABSTRACT:
Permanent magnets are mounted on a rotor of an electrical motor by an apparatus that keeps an adhesive bonding layer between the magnet and rotor in compression over wide variations in temperature and speed of rotation. The mechanical stresses on the magnets are controlled using compliant layers and spacers. The apparatus allows the removal and replacement of individual magnets.
