Abstract

A rotor assembly is provided in which the rotor assembly includes a first core portion, wherein the first core portion has at least one first core protrusion, and a second core portion, wherein the second core portion has at least one second core protrusion. The first core portion and the second core portion are configured to be matingly coupled to each other so as to form an assembled rotor assembly. In addition, the rotor assembly includes a number of magnetizable members wherein respective ones of the magnetizable members are coupled to each of the first core protrusions and coupled to each of the second core protrusions. The magnetizable members are adapted to be coupled to a magnetizing fixture prior to mating the first and second core portions so as to magnetize the magnetizable members.
