Rotor, electric machine and associated method

An electric motor comprising;

• a housing;
• a stator fixedly secured to said housing;
• and
• a rotor, said rotor rotatably secured to housing, said rotor including a body defining a center of rotation thereof, said body further defining a first surface extending in a direction generally perpendicular to the center of rotation and further defining a second surface extending in a direction generally parallel and spaced from the first surface;
• a magnet connected to the said body;
• and an adhesive, said adhesive positioned between said magnet and said body and adapted to assist in securing said magnet to said body, the first surface and the second surface of said body adapted to permit removal of material therefrom to assist in balancing of said rotor.

A method for making a rotor for an axial flux electric motor, the method comprising the steps of:

• fabricating a rotor, said rotor including a body defining a center of rotation thereof, said body further defining a first surface extending in a direction generally perpendicular to the center of rotation and further defining a second surface extending in a direction generally parallel and spaced from the first surface;
• applying an adhesive to a magnet connecting surface of the body;
• performing a balance test on the rotor;
• removing material from the first surface of said body;
• and
• removing material from the second surface of said body.
