Abstract: The rotor comprises rotor segments consisting of a magnetically conductive material, which segments are distributed across the circumference of a rotor housing. Rotor housing portions of low magnetic conductivity are located between the rotor segments. The rotor segments are embedded in a main body in such a way that the outside or inside of the main body forms a closed housing. To produce the rotor a star-shaped blank is punched out of a metal sheet, the arms of said blank being bent out in relation to a central part connecting said arms, in order to form the rotor segments.

Abstract: An internal permanent magnet machine has multiple rotor sections, each section having multiple rotor laminations. Permanent magnets are placed asymmetrically in lamination openings to attenuate oscillations in torque caused by harmonic components of magnetic flux. Asymmetry is achieved by placing adjacent permanent magnets or magnet sets on the rotor periphery with different rotor magnetic pole arc angles.
