Embodiment 1
[0031] This embodiment is a method for arranging stator windings of a circumferentially-wound high heat dissipation rate automotive generator. figure 1 The magnetic field on the circumference of the stator winding will be differentiated into two types of magnetic field lines. One is when the rotor magnetic pole 201 is N-level as shown in the figure, it is aimed at the three magnetic poles between the stator slot circuit ①--④ The magnetic lines of force are divided into two directions on the circumference of the stator, combined with the attached image 3 It can be seen that one path is divided into the circumferential iron core passing upwards between the inner and inner grooves ① and the corresponding outer grooves 181, and its magnetic field lines are shown as 130 in the figure, and the other path is divided into downwards passing through the inner grooves ④ and the outer grooves. Circumferential iron core between 182, its magnetic field line is shown as 131 among the figure...
Embodiment 2
[0037] Such as Figure 4 As shown in the figure, the generator stator core and winding structure using this circumferential winding high heat dissipation rate automotive generator stator winding arrangement method, the stator includes an axially slotted stator core and stator windings, and the stator core is in a circular structure 1. The inner circle side of the circular structure is provided with a number of inner grooves along the axial direction, and the outer circle side of the circular structure is covered with an insulating support with several outer grooves arranged in the axial direction. The insulating support is close to the outer wall of the stator core circumference , the plastic bracket can be used, or the bracket can be processed directly on the stator core by a process such as injection molding. The outer edge of the bracket has an outer groove and an outer tooth corresponding to the corresponding inner groove, such as Figure 4 As shown, the part enclosed betw...
