A high-reliability driving motor for electric vehicle belongs to the technical field of electric vehicle, and comprises a shell, a permanent magnet, a non-magnetic conductive rotor core, a magnetic conductive rotor core, a stator core, an armature winding, an excitation winding and the like. The stator core is divided into 12 sub-core non-conductive rotor cores with 14 isosceles trapezoidal grooves. The isosceles trapezoidal conductive rotor core is embedded in the tripod-shaped grooves. There are two downward increasing dovetail bumps stuck on the tail end of the core of the non-magnetic conductive rotor. A radially magnetized permanent magnet is fixed on the stator pole on one side of the stator core, wherein an excitation winding is wound on one side of the stator pole, and an armaturewinding is wound on the stator pole on the other side of the stator core. The generator of the invention has independent stator iron core, each winding is isolated from each other, and fault propagation can be effectively prevented; meanwhile, the hybrid excitation drive motor of the invention has the advantages of simple structure, large stator-rotor contact surface, high power density and the like.
