ROTOR FOR ROTATING ELECTRIC MACHINE

摘要

A rotor for a synchronous reluctance machine having an even number 2p of poles circumferentially spaced at an angle ±, with ±=2À/2p, said rotor comprising a substantially cylindrical laminate stack having a plurality of magnetically conductive laminations. One or more of said magnetically conductive laminations comprises non-magnetic flux barriers which are spaced from each other in the radial direction, one or more of said non-magnetic flux barriers having a first and a second bridge transversally positioned in correspondence of their lateral ends and defining a first and a second air-gap with the outer rim of said magnetically conductive lamination, and further comprising a third and a fourth bridge transversally positioned and respectively defining together with said first and second bridge a first and a second internal space which are filled with an electrically conductive and non-magnetically conductive material
