Document Type and Number:
WIPO Patent Application WO/2014/025882
Kind Code:
A3
Abstract:
In some embodiments, an electromagnetic machine includes a rotor element configured for movement relative to a stator. The rotor element includes a support member, a backing member, and a magnetic pole assembly. The support member includes a first coupling portion. The backing member is formed, at least in part, from a ferromagnetic material and the magnetic pole assembly is configured to be coupled to the backing member. The magnetic pole assembly and/or the backing member include a second coupling portion configured to removably couple the backing member and the magnetic pole assembly collectively to the first coupling portion of the support member.
