Abstract
A shaft cover structure for use in an exciter is provided. The shaft cover structure comprises at least two sections located about a selected portion of a rotatable shaft. The sections are positioned such that adjacent circumferential ends of the at least two sections are spaced apart to define gaps therebetween. A recess extends from each circumferential end such that adjacent recesses define a slot. A spanning member is disposed in each of the slots such that the sections and the spanning members cooperate to form a continuous cover member that surrounds the selected portion of the shaft. A first holding structure secures the continuous member on the selected portion of the shaft.
