Abstract: The disclosure discloses a driving motor with an asymmetrical magnetic pole type of permanent magnet and claw pole electric excitation for an electric automobile which includes a front end cover, a rear end cover, a housing, an asymmetric magnetic pole type of permanent magnet rotor, a claw pole electric excitation rotor, and a stator. Wherein the asymmetric magnetic pole type of permanent magnet rotor is provided with first magnetic pole groups and second magnetic pole groups, the first magnetic pole groups and the second magnetic pole groups are of an asymmetric structure, polarities of outer sides of the first magnetic pole groups and the second magnetic pole groups are distributed in a manner of N poles and S poles arranged at intervals. A utilization of inner space of the motor rotor can be improved, the performance of the motor is improved, and the costs of the motor are reduced.
