PERMANENT-MAGNET SYNCHRONOUS MOTOR AND ELECTRIC POWER-ASSISTED STEERING SYSTEM

摘要

The present invention relates to a permanent-magnet synchronous motor, particularly an electric three-phase motor, comprising a stator (300) having a stator yoke (301) in which stator teeth (302) with interposed stator grooves (202) are arranged, wherein on each stator tooth (302) at least one winding (303) is provided, further comprising a rotor (204) having permanent magnets (203), wherein the stator teeth (302) are arranged in layers as disks in the axial direction of the stator (300) and designed at least as two different disks, wherein the stator teeth (302) in a first disk are connected peripherally among each other at the ends thereof pointing toward the rotor (204) in the form of a stator star (305) by a connecting bridge (401) and in a second disk have an interruption (402) instead of the connecting bridge (401). The present invention further relates to an electric power-assisted steering system.
