ROTOR ASSEMBLY OF AN ELECTRIC MACHINE COMPRISING A SHEATH

A rotor assembly (302) comprising rotatable element (112) comprising an outer periphery (114), a set of first elements (118) forming magnetic poles and a set of second elements (120) forming inter-polar regions and a containment band (322). Said set of first elements (118) and said set of second ele...

More Information
Summary:A rotor assembly (302) comprising rotatable element (112) comprising an outer periphery (114), a set of first elements (118) forming magnetic poles and a set of second elements (120) forming inter-polar regions and a containment band (322). Said set of first elements (118) and said set of second elements (120) are alternately placed on the outer periphery (114) of the rotatable element (112) and are retained by said containment band (322). Said containment band (322) is made out of alternating portions of a first material (324) and of a second material (326) in order to enhance the flow of the magnetic flux evoked by said first and second elements. Each of said portions (324, 326) is overlying at least partially one of said first elements (118) or second elements (120).
