Abstract
The present disclosure relates to a motor rotor, a permanent magnet motor, and an electric vehicle. The motor rotor includes a rotor core () and permanent magnets (). The rotor core () includes mounting slots (). The permanent magnets () are arranged in the mounting slots (). An included angle between two mounting slots () forming a V-shaped structure in the mounting slots () is Δ. A numerical value of a thickness of the permanent magnets () is L4 when a unit thereof is mm. A numerical value of a width of the permanent magnets () is L5 when a unit thereof is mm. 110°≤Δ≤140°. A numerical value of Δ=(18 to 20)*L4, L5≥2*L4.
