Abstract
The utility model relates to an electric vehicle used direct current motor stator. The stator comprises a magnetic shoe seat and a magnetic shoe, characterized in that the equally divided position of the inner round circle on the magnetic shoe seat is fixedly equipped with even number of magnetic shoe fixing pieces, the magnetic shoe is equipped between adjacent magnetic shoe fixing pieces, two sides of the magnetic shoe fixing pieces are equipped with a side wall which blocks the magnetic shoe side wall, the upper end of the side wall is equipped with a folding line being folded and pressed on the magnetic shoe outward, two ends of the magnetic shoe fixing piece are also equipped with an axial fixing fin extending towards the slant upper on two sides which is blocked between two ends of the magnetic shoe, and the magnetic shoe fixing pieces adopts springy metal materials for manufacturing. The stator has the advantages of stable magnetic shoe fixing, precise locating, quick and convenient equipment and the like, which not only can effectively increase the output power of the direct current motor, prolongs the using life of the motor, but also can make the equipment speed of the motor greatly increased, thereby increasing the production efficiency.
Description
Technical field
The utility model belongs to the dc motor technology field, is specifically related to a kind of electric vehicle DC motor stator.
Background technology
In existing electric vehicle DC motor stator, its magnetic shoe generally is to adopt fixing glue to stick on the magnetic shoe seat.The magnetic shoe of employing glue is not only located accurate inadequately, and easy loose or dislocation; And magnetic shoe is located not criterion and is caused magnetic line of force skewness or magnetic line of force direction to produce skew easily, and it is unstable to cause motor to rotate, and power loss is bigger, and the lower and motor of motor power output damages easily.In addition,, need the long time just competent solid, the assembling progress of motor is affected, so its production efficiency is lower because magnetic shoe sticks with glue.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides that a kind of magnetic shoe is fixed, the location accurately, and assemble electric vehicle DC motor stator fast and easily, thereby improve the power output and the useful life of direct current machine.
The purpose of this utility model realizes as follows: a kind of electric vehicle DC motor stator, comprise magnetic shoe seat, magnetic shoe, the position of halving that is characterized in the inner periphery of magnetic shoe seat is installed with even number magnetic shoe fixture, be equipped with magnetic shoe between the adjacent magnetic shoe fixture, wherein all there is the sidewall of retaining in the magnetic shoe side magnetic shoe fixture both sides, sidewall upper is provided with laterally bending and is pressed in flanging on the magnetic shoe, magnetic shoe fixture two ends also be provided with to the both sides oblique upper extend and retaining at the axial restraint wing at magnetic shoe two ends.
Magnetic shoe fixture of the present utility model adopts elastic metallic material to make.
Because each magnetic shoe fixture is fixedly arranged on the position of halving of magnetic shoe seat inner periphery, the magnetic shoe fixing by the magnetic shoe fixture also just is fixed on the magnetic shoe seat equably, and blocked by sidewall on the magnetic shoe fixture of its both sides and axial restraint wing respectively around the magnetic shoe, the flanging of sidewall upper is pushed down magnetic shoe simultaneously, make magnetic shoe on the magnetic shoe seat, can not produce any moving, therefore, the magnetic shoe location of this stator is accurate, fixed, the magnetic line of force is evenly distributed, can make the motor stability of rotation, power loss is less, and the power output of direct current machine and useful life are improved.In addition, this stator also has and assembles advantage fast and easily, can accelerate the assembling speed of motor complete machine, thereby improve its production efficiency.

Fig. 2 is the A-A cut-away view of Fig. 1.
Fig. 3 is the structural representation of the utility model magnetic shoe fixture (3).
Fig. 4 is the left view of Fig. 3.
Among the figure: 1 expression magnetic shoe seat; 2 expression magnetic shoes; 3 expression magnetic shoe fixtures; 4 expression sidewalls; 5 expression axial restraint wings; 6 expression flangings; 7 expression rivets; 8 expression rivet clasp holes.
Embodiment
The utility model will be further described below with reference to drawings and Examples.
As shown in Figure 1 and Figure 2, the electric vehicle DC motor stator has magnetic shoe seat 1, there are four magnetic shoe fixtures 3 that adopt elastic metallic materials to make position 90 ° of the each intervals of magnetic shoe seat 1 inner periphery by rivet 7 rivet clasps, as shown in Figure 3, Figure 4, all there is sidewall 4 magnetic shoe fixture 3 both sides, sidewall 4 upper ends have the flanging 6 of bending laterally, the axial restraint wing 5 that also oriented both sides, magnetic shoe fixture 3 two ends oblique upper extends.When magnetic shoe 2 is installed, only need axial restraint wing 5 is depressed, just can will push the space of magnetic shoe 2 between flanging 6 and axial restraint wing 5, magnetic shoe 2 can be fixed between each adjacent magnetic shoe fixture; Owing to blocked by sidewall 4 on the magnetic shoe fixture 3 of its both sides and axial restraint wing 5 respectively around the magnetic shoe 2, the flanging 6 of sidewall 4 upper ends is pushed down magnetic shoe 2 simultaneously, makes magnetic shoe 2 can not produce any moving on magnetic shoe seat 1.Therefore, this stator has magnetic shoe fixation, accurate positioning, assembles advantage fast and easily, can effectively improve the power output of direct current machine, the useful life of prolongation motor.
Claims (2)
1. electric vehicle DC motor stator, comprise magnetic shoe seat (1), magnetic shoe (2), the position of halving that it is characterized in that the inner periphery of magnetic shoe seat (1) is installed with even number magnetic shoe fixture (3), be equipped with magnetic shoe (2) between the adjacent magnetic shoe fixture, wherein all there is the sidewall (4) of retaining in the magnetic shoe side magnetic shoe fixture (3) both sides, sidewall (4) upper end is provided with bending laterally and is pressed in flanging (6) on the magnetic shoe, magnetic shoe fixture (3) two ends also be provided with to the both sides oblique upper extend and retaining at the axial restraint wing (5) at magnetic shoe two ends.
2. electric vehicle DC motor stator according to claim 1 is characterized in that magnetic shoe fixture (3) adopts elastic metallic material to make.
