Synchronous reluctance motor with magnetic flux barriers

A synchronous reluctance motor, comprising:

• a rotor including a rotor core;
• and
• a stator surrounding the rotor on a radial outer side;
• wherein
• the rotor core is provided with a plurality of magnetic barrier groups spaced apart in a circumferential direction;
• each of the plurality of magnetic barrier groups includes three or more magnetic barriers arranged in a radial direction, and a magnetic conduction segment is provided between every two adjacent magnetic barriers;
• the plurality of magnetic barriers in each of the magnetic barrier groups each has a shape that protrudes toward a radial inner side and is symmetrical about a q-axis, and a portion closer to a circumferential side than the q-axis includes a first portion extending perpendicular to the q-axis, and a second portion extending farther toward the circumferential side from a circumferential side of the first portion and radially outward;
• the first portions of the plurality of magnetic barriers in each magnetic barrier group have a same radial dimension;
• among the plurality of magnetic barriers in each magnetic barrier group, the first portions of the magnetic barriers other than the radial outermost magnetic barrier have a same circumferential dimension, which is the same as or twice a circumferential dimension of the first portion of the radial outermost magnetic barrier;
• and
• for a radial innermost magnetic barrier among the plurality of magnetic barriers in each magnetic barrier group, an angle formed by a connecting line of an end on the circumferential side of a radial outer edge of the first portion and a center of rotation of the rotor with respect to the g-axis is set to, and an angle formed by a connecting line of an end on the circumferential side of a radial inner edge of the second portion and the center of rotation of the rotor with respect to a d-axis is set to β, and 2.8°<β<4.6° is satisfied.
