OPTIMISATION OF THE ROTOR OF A PERMANENTLY EXCITED SYNCHRONOUS MACHINE FOR REDUCING THE COG TORQUE AND TORQUE RIPPLE

摘要

the invention relates to an electrical machine, preferably a permanent-magnet synchronmaschine is executed and a pedestal base (1) and a rotor (4) has a läuferkern.the runners are arranged permanentmagnete (2).at the bottom of the permanentmagnete (2) and / or in one of the permanentmagnete (2) adjacent the area of läuferkerns (4) material is omitted (3, 5).as a result, the torque ripple and the nutrastmoment electrical machine is reduced.
