Document Type and Number:
Japanese Patent JP6598993
Kind Code:
B2
Abstract:
A rotor includes a first permanent magnet, a second permanent magnet, and an electromagnetic steel sheet. The electromagnetic steel sheet includes a magnet insertion hole, a projection, a first end part, a second end part (211b), a third end part, and a fourth end part. The rotor satisfies an expression of t≤2×w×sin(R/2)≤2×t, where t is a thickness of the electromagnetic steel sheet, R is an angle formed by the third end part and the fourth end part, and w is a distance from an intersection point of a straight line including the first end part and a straight line including the third end part to an intersection point of a straight line including the third end part and a straight line including the fourth end part.
