TAPERED AIR-GAP AXIAL DUAL-LOOP MAGNETIC FIELD PERMANENT MAGNET SYNCHRONOUS MOTOR

摘要

A tapered air-gap axial dual-loop magnetic field permanent magnet synchronous motor comprises a housing (8), and stator iron cores (1) and rotors (4) provided in the housing. Two of the stator iron cores are disposed in the housing after end surfaces of the two of stator iron cores are fit to each other. An outer end of each stator iron core is formed with a tapered surface (1-1). Each tapered surface is correspondingly provided with a rotor, with magnetic steel (3) of different polarities interlaced thereon. A protrusion (8-1) is formed at a center position on an inner wall of the housing. Each stator iron core is provided with a stator winding (2) wound thereon, and two of the stator windings are separated from each other by the protrusion. The motor has an increased manufacturing and assembling efficiency and an increased operation efficiency.
