Abstract: An assembly includes multiple adjoined rotor sections each having multiple poles and multiple void rows therethrough that are radially distributed in each of the poles. The rotor sections are skewed in a circumferential direction. The assembly also has multiple conductive rings that substantially surround one of the void rows. A method of assembly and electric machines and vehicles using the assembly are also disclosed. Aspects reduce torque ripple in electric machines and allow for encoderless/sensorless operation in an electric machine using the rotor assembly. The present invention has been described in terms of specific embodiment(s), and it is recognized that equivalents, alternatives, and modifications, aside from those expressly stated, are possible and within the scope of the appending claims.
