Optimized design method of claw poles of automotive generator rotor

The invention discloses an optimized design method of claw poles of an automotive generator rotor. The whole optimized design process is finished by adopting the steps of carrying out optimized design on claw pole structure parameters in an automotive generator by taking improvement of efficiency and a beam of uniform strength as sub-goals to respectively obtain a claw pole structure parameter range and finally optimizing the whole performance of the generator by combining the two sub-goals as a system optimized design goals to obtain a final optimized claw pole structure parameter range. The optimized design method disclosed by the invention achieves the purposes of both considering the electromagnetic performance and the mechanical performance of the generator and improves the operation performance of the generator.
