The invention provides a claw pole hot forging part and a manufacturing method of a claw pole, and belongs to the technical field of motors. According to the claw pole hot forging part and the manufacturing method of the claw pole, the problem of loud noise of an existing claw pole motor is solved. According to the claw pole hot forging part, a claw pole forming part comprises a support part and multiple claw pole fingers which are uniformly distributed along the circumference of the axial line of the support part; the claw pole fingers are connected with the support part through claw pole finger roots; and each claw pole finger root of the claw pole hot forging part is provided with a material reinforcing part at the periphery, with respect to each claw pile finger root of the claw pole forming part. Through the claw pole hot forging part and the manufacturing method of the claw pole, as metal of each claw pole finger root is deformed, the metal density is improved and a cold hardening effect is generated, hardness and mechanical intensity of the claw pole finger roots of the claw pole forming part are further improved significantly, and the vibration frequency is further changed. Experiments prove that the noise of the claw pole motor adopting the claw pole can be reduced at least for 5 decibels.
