Abstract:

The object of this program was to demonstrate the feasibility of magnetizing large rare earthcobalt permanent magnets subsequent to their assembly in complex rotor structures. A safe demagnetization to near zero remanence technique was optimized and demonstrated on individual magnets with insignificant detrimental affect on the magnet physical properties. Magnetic finite element analysis was completed which optimized the winding location requirements for the magnetization and substantiated that remagnetization of large rare earthcobalt permanent magnets assembled in complex rotor structures is feasible if the magnetic field could be obtained.
