Embodiment 1

[0017] Such as figure 2 As shown, the structure of the hybrid excitation motor claw pole hot forging and the hybrid excitation claw pole forming part are basically the same, the main difference is: the inner wall surface 2a of the claw pole finger 2 and the two outer surfaces There are magnet installation preformed grooves 5 between the sides 2b, the cross-sectional area of ​​the magnet installation preformed grooves 5 is smaller than the cross-sectional area of ​​the magnet installation grooves 3, and the top surface of the claw pole finger root has a connection with the magnet installation preformed grooves 5. The waste accumulation tank 12.

[0018] Such as image 3 As shown, the side 5a of the magnet installation preformed groove is the same as the bottom surface of the magnet installation groove 3, and the transition between the side 5a of the magnet installation preformed groove and the outer surface 2b of the claw pole finger 2 adopts an arc surface 10. Specifically,...

Embodiment 2

[0025] The structure and principle of this embodiment are basically the same as that of Embodiment 1, and the basic similarities will not be redundantly described, and only the differences will be described, and the differences are as follows: Figure 4 As shown, the side 5a of the magnet installation preformed groove is the same as the bottom surface of the magnet installation groove 3, and the one side 5a of the magnet installation preformed groove and the outer surface 2b of the claw pole finger 2 adopt multiple slopes and arc surfaces 10 for transition. Specifically, the inclined surfaces include a first inclined surface 8 inclined to one side 5a of the preformed groove for magnet installation and a second inclined surface 9 inclined to the first inclined surface 8, and the arc surface 10 connects the second inclined surface 9 and the claw pole fingers 2 The outer side 2b. The angle α between the first slope 8 and one side 5a of the preformed groove for magnet installation...

Abstract

The invention provides a hybrid excitation motor claw pole hot forged piece and a hybrid excitation motor claw pole manufacturing method, and belongs to the technical field of motors. The problems of a long manufacturing period and a high manufacturing cost of the existing claw pole manufacturing process are solved. Magnet installation pre-formed grooves are arranged among an inner side surface and two outer side faces of a claw pole finger in the hybrid excitation motor claw pole hot forged piece, the cross sectional area of the magnet installation pre-formed groove is smaller than that of a magnet installation groove, and a top face of a claw pole finger root is provided with a waste accumulation groove communicated with the magnet installation pre-formed groove. The claw pole hot forged piece is suitable for being formed into a claw pole formed piece by cold extrusion at one time. The hybrid excitation motor claw pole hot forged piece and the hybrid excitation motor claw pole manufacturing method used for manufacturing the claw pole have the advantages of shortening the manufacturing period, reducing the manufacturing cost and improving the market competitiveness of the claw pole.

Description

technical field [0001] The invention belongs to the technical field of motors, and relates to a hybrid excitation motor, in particular to a method for manufacturing claw poles of a hybrid excitation motor. Background technique [0002] As a driving device that converts electrical energy into mechanical energy output, the motor is widely used in industries, home appliances, automobiles and other fields. Among them, the claw pole motor has a wide range of applications in the automotive field due to its advantages of low structural cost and simple driving circuit. Hybrid excitation motor is a kind of claw pole motor; claw pole is one of the core components of claw pole motor. Such as figure 1 The claw pole shown is a hybrid excitation motor claw pole. Relevant documents about the manufacturing method of hybrid excitation motor claw poles such as a kind of automotive generator claw poles and its manufacturing process (application publication number CN104493442A) recorded in C...
