ABSTRACT:
In a method of assembling a rotatable assembly, a rotor core is disposed with its circumferential surface coaxial with a reference axis, and arcuate outer surfaces of a set of magnet material elements are located in preselected positions generally concentrically about the reference axis. With the arcuate outer surfaces located in the preselected positions, the magnet material elements are then arranged with respect to the rotor core so that the arcuate outer surfaces located in the preselected positions define a predetermined outside diameter of the rotatable assembly, and the arcuate inner surfaces of the magnet material elements are in spaced apart relation from the circumferential surface of the rotor core at least within a preselected spatial range.
Apparatus and a method of operating apparatus are also disclosed.
