Title:
PERMANENT MAGNET SYNCHRONOUS MOTOR
Document Type and Number:
WIPO Patent Application WO/2023/223561
Kind Code:
A1
Abstract:
In the present invention, a permanent magnet synchronous motor (50) comprises: a stator (8); a plurality of teeth (2T) arranged at equiangular intervals on the stator (8); and a coil (1) wound around each of the plurality of teeth (2T) in a concentrated winding, each coil (1) constituting a three-phase delta connection. In a magnetic closed circuit in which the magnetic flux generated from the coil (1) wound around one of two adjacent teeth included in the plurality of teeth (2T) passes through the coil (1) wound on the other tooth of the two teeth via the tips of the two teeth and then returns to the coil (1) wound around the one tooth via the core back part of the two teeth, the magnetic resistance of the magnetic closed circuit when the coils (1) wound around the two teeth are in phase is less than the magnetic resistance of the magnetic closed circuit when the coils (1) wound around the two teeth are out of phase.
