Detailed description of the invention
Presently in connection with accompanying drawing, this utility model is further described.These accompanying drawings are the schematic diagram of simplification, only with
Illustration illustrates basic structure of the present utility model, and therefore it only shows the composition relevant with this utility model.
A kind of motor with longer life as shown in Figure 1, 2, including stator core 1, in stator core 1 endoporus
Being equipped with rotor assembly, rotor assembly includes armature spindle 2, be provided with between rotor assembly and stator core 1 endoporus four to for around
If the winding body of coil 3, winding body 3 is uniform and be connected as a single entity with stator core 1 along stator core 1 endoporus circumference, winding body 3 with
Offer five axial teeth groove 4 on the arcwall face that rotor assembly is relative, stator core 1 be respectively arranged at two ends with drive end bearing bracket 5 and after
End cap 6, is respectively equipped with the rolling bearing 7 of rotational support armature spindle 2 in the dead eye of drive end bearing bracket 5 and rear end cap 6, armature spindle 2 drives
Moved end is protruding by the dead eye of drive end bearing bracket 5, and the dead eye of rear end cap 6 is blind hole, rolling bearing 7 outer ring in blind hole with
Being provided with wave washer 8 between blind via bottom, wave washer 8 two ends offset with this rolling bearing 7 outer ring and blind via bottom respectively, when
Rolling bearing 7 works long hours after abrasion, and rolling bearing 7 outer ring is axially moveable under the elastic force effect of wave washer 8, to keep away
Exempt to produce between rolling bearing 7 roller and the inside and outside circle of rolling bearing gap.
For improving the output torque of motor, on described armature spindle 2, fixed cover is equipped with annular magnetic steel 9, annular magnetic steel 9
It is respectively arranged at two ends with the rotor core 10 being fixedly set on armature spindle 2；A pair head and the tail it is inlaid with in described winding body 3 teeth groove 4
The magnetic stripe 11 being connected, two magnetic stripe 11 opposite polarity.
Above-mentioned embodiment only for technology of the present utility model design and feature are described, its object is to allow and is familiar with this skill
The personage of art will appreciate that content of the present utility model and is carried out, and can not limit protection model of the present utility model with this
Enclose, all equivalence changes made according to this utility model spirit or modification, all should contain at protection model of the present utility model
In enclosing.
