System and method for magnetizing rare earth metals to construct a rotor assembly

A system to magnetize one or more rare earth metals to construct a rotor assembly, comprising:

• one or more laminated sheets are stacked together to construct a laminated block;
• one or more laminated blocks stacked together to construct the rotor assembly, wherein the rotor assembly comprises one or more surfaces on an outer periphery of the rotor assembly;
• the rotor assembly comprises one or more slots mechanically configured to provide a predetermined space to position the one or more rare earth metals in a non-magnetized state;
• and
• a magnetization unit comprises one or more magnetizing surfaces, and one or more magnetizing windings, wherein the one or more magnetizing surfaces are configured to magnetize the one or more rare earth metals of the rotor assembly by passing a predetermined supply using the one or more magnetizing windings.

A method of magnetizing one or more rare earth metals to construct a rotor assembly, comprising:

• stacking one or more laminated sheets together to construct a laminated block;
• positioning the one or more rare earth metals into one or more slots;
• gluing the one or more rare earth metals into the one or more slots;
• stacking, using one or more joining processes, one or more laminated blocks in presence of a rotor shaft 302 to construct the rotor assembly with one or more balancing rings;
• balancing the rotor assembly, wherein the rotor assembly comprises one or more surfaces on an outer periphery, wherein the one or more surfaces of the rotor assembly comprise a first predetermined shape;
• disposing of the rotor assembly into a magnetization unit, wherein the magnetization unit comprises one or more magnetizing surfaces, and one or more magnetizing windings, wherein the one or more magnetizing surfaces of the magnetization unit comprise a second predetermined shape;
• correspondingly positioning the first predetermined shape and the second predetermined shape together in a manner to avoid wrong positioning of the rotor assembly with the magnetization unit;
• positioning the one or more surfaces of the rotor assembly at a predetermined distance from the one or more magnetizing surfaces of the magnetization unit, wherein the predetermined distance varies based on the outer periphery of the rotor assembly, positioning of the first predetermined shape of the one or more surfaces and the second predetermined shape of the one or more magnetizing surfaces and orientation of the one or more rare earth metals;
• converging magnetic flux lines from the magnetization unit to the one or more rare earth metals using the one or more surfaces of the rotor assembly, one or more flux concentrators, and the one or more magnetizing surfaces of the magnetization unit, wherein the magnetization unit further comprises the one or more flux concentrators;
• and
• magnetizing, using the one or more magnetizing windings, the one or more rare earth metals by passing a predetermined supply, wherein the one or more magnetizing windings comprise different polarities.
