ROTOR FOR AN ELECTRIC MACHINE, AN ELECTRIC MACHINE AND METHOD FOR MANUFACTURING AN ELECTRIC MACHINE
Abstract:
A rotor for an electric machine includes a rotor core having a plurality of rotor sheets (RS1), each of the plurality of rotor sheets including a plurality of flux guide sections, each of the plurality of flux guide sections having a plurality of flux paths and a plurality of flux barriers. The plurality of flux guide sections having a first flux guide section in which a first number of the plurality of flux barriers has a bridge interrupting the flux barrier, and a second flux guide section in which a second number of the plurality of flux barriers has a bridge interrupting the flux barrier. Each bridge is made of a material of high permeance, and the first number of the first flux guide section is different than the second number of the second flux guide section.
