Permanently excited rotor for electrical machine, has triangular shaped bar that is adjusted on central longitudinal axis of rotor, where cross section of bar is defined to permanent magnet by radial distance between auxiliary magnets

摘要

The rotor (2) has magnetized permanent magnets (10) that are arranged in a radial direction, and auxiliary magnets (20). The auxiliary magnets are arranged between the two permanent magnets under formation of a triangular shaped bar that is spaced apart from the permanent magnets. The triangular shaped bar is adjusted on a central longitudinal axis of the rotor. The cross section of the bar is defined to the permanent magnet by the radial distance between the auxiliary magnets. The auxiliary magnets are arranged in circle-arc-shaped manner in the rotor.
