Abstract
A method of assembling a rotatable assembly. A set of generally arcuate magnet material elements are moved toward assembly positions with respect to a circumferential surface of a rotatable member. During this movement, the positions of at least some of the magnet material elements are adjusted generally circumferentially about the circumferential surface of the rotatable assembly to establish at least generally equal gaps between adjacent opposed ones of a pair of opposite marginal edges on the magnet material elements defining the arcuate lengths thereof, respectively. Apparatus for assembling a rotatable assembly and a method of operating such apparatus are also disclosed.
