Patent ID: 11362574

Abstract:
A rotor for a synchronous reluctance machine includes a rotor core having a plurality of magnetically conductive laminations stacked in a rotor axial direction. The magnetically conductive laminations include cut-out portions forming a plurality of flux barriers radially alternated by flux paths portions, where at least one of the flux barriers includes a ridge connecting two flux paths portions adjacent to the at least one flux barrier. The at least one flux barrier has a first barrier mid-line, which is a line that is equidistant from both sides of the at least one flux barrier. The bridge has a second bridge mid-line, which is the line that is equidistant from both sides of the bridge. The first and second mid-lines intersect. The bridge has a first and second symmetry axis and is non-symmetrical with respect to at least one of the first and second symmetry axis.
