Abstract
A method of assembling a shaft of a magnetic motor comprising the steps of providing a plurality of magnets (), providing a plurality of pole pieces (), stacking (S) said magnets and pole pieces to form a subassembly () having an outer surface of a first diameter, providing a precipitation hardenable stainless steel sheet material, forming said stainless steel sheet material into a tube (S), drawing said tube to form a precision tube having an inner surface of a second diameter (S), said second diameter being greater than or equal to said first diameter, heat treating said precision tube to form a tubular sleeve of a Rockwell C hardness of at least about 40 and a magnetic permeability of at least about 100 (S), and inserting said subassembly axially into said sleeve (S), thereby forming a shaft for a magnetic motor.
