23. The method of assembling a shaft of a magnetic motor, comprising the steps of:
-
providing an elongated core; providing a plurality of magnets; providing a plurality of pole pieces; stacking said magnets and pole pieces along said core in an alternating fashion to form a subassembly having an outer surface of a first diameter; providing a tubular sleeve having an inner surface of a second diameter, said second diameter being less than or equal to said first diameter; temporarily distorting at least one of said subassembly and sleeve so as to permit said subassembly to be inserted axially into said sleeve; inserting said subassembly axially into said sleeve; and allowing each of said subassembly and sleeve that had been temporarily distorted to move back toward its original undistorted shape so as to form a tight interference fit between said subassembly and sleeve; thereby to form a shaft for a magnetic motor. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31)
