Title:
DISK-TYPE THREE-PHASE BRUSHLESS PERMANENT MAGNET DIRECT CURRENT MOTOR
Document Type and Number:
WIPO Patent Application WO/2014/121466
Kind Code:
A1
Abstract:
A disk-type three-phase brushless permanent magnet direct current motor comprises: a first disk rotor (110) and a second disk rotor (120), which are arranged parallel to and opposite to each other; a first plastic permanent magnet (210) and a second plastic permanent magnet (220), which are arranged on the surfaces of the first disk rotor and the second disk rotor, respectively, and arranged opposite to each other; and a disk stator (300) arranged parallel between the first plastic permanent magnet and the second plastic permanent magnet. The mechanical structures and magnetic structures of the first plastic permanent magnet and the second plastic permanent magnet are the same; the polarities of any one magnetic pole in the first plastic permanent magnet and a magnetic pole in the second plastic permanent magnet right opposite to this magnetic pole are the same to generate an axial air gap field with an electromagnetic air gap of δ; and a first surface (301) and a second surface (302) of the disk stator are both uniformly provided with virtual slots, and a three-phase full pitch winding (310) is mounted in the virtual slots. By adopting plastic permanent magnets, not only is the cost low, but also the aim of being ultrathin can be realized; and the air gap field is a repulsion force field, which can effectively suppress the iron loss of a motor.
