Abstract
The present disclosure provides a motor rotor and a permanent magnet motor. The motor rotor includes a rotor body. In a section perpendicular to a central axis of the rotor body, a first slot side has a first and a second endpoint, and a second slot side has a third and a fourth endpoint. A distance from a connecting line between the first endpoint and the third endpoint to a center of the rotor body is denoted by h1, a radius of the rotor body is denoted by R, and h1 and R satisfy 0.96≤h1/R≤0.99. A connecting line between the first endpoint and the center of the rotor body is a first connecting line, a connecting line between the third endpoint and the center of the rotor body is a second connecting line, and an included angle between the two connecting lines is denoted Φ and satisfies: 3.7°≤Φ≤5.6°.
