ABSTRACT:
A method of balancing an embedded permanent magnet motor rotor includes the steps of: a) providing a non-magnetic cylindrical shaft having an axis of rotation and a generally cylindrical surface with an even number of recessed slots defining an even number of ribs therebetween; b) machining an axial slot having a cross-section with a top opening, a bottom and two sides in a center portion of each of the recessed slots; c) sliding at least one balance weight into at least one of the axial slots; and d) inserting locating rods into the axial slot on each side of the at least one balance weight.
