Description of the drawings
Fig. 1 is schematic structural view of the invention;
Fig. 2 is left view sectional view of the present invention.
In figure:1 housing, 2 acoustical cotton layers, 3 protective shells, 4 bearings, 5 drive links, 6 polygonal columns, 7 electric telescopic rods, 8 are fixed Card, 9 heat emission holes, 10 shafts, 11 permanent-magnet poles, 12 coil windings.
Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work Embodiment belongs to the scope of protection of the invention.
- 2 are please referred to Fig.1, the present invention provides a kind of technical solution:A kind of special non-brush permanent-magnet DC motor of electric vehicle, Including housing 1, the outer wall of the housing 1 is enclosed with acoustical cotton layer 2, and the outer wall of the acoustical cotton layer 2 is enclosed with protective shell 3, institute The right side for stating housing 1, acoustical cotton layer 2 and protective shell 3 is inlaid with one group of bearing 4, and the inner cavity of the bearing 4 has extended transversely through transmission Bar 5, the left end of the drive link 5 is connected with polygonal column 6, and polygonal column 6 is located at the inner cavity of housing 1, the left side of the polygonal column 6 Shaft 10 is connected with, electric telescopic rod 7 is mounted at the top and bottom of 1 inner cavity of housing, and two groups of electric telescopic rods 7 are equal With polygonal column 6 in same vertical centerline, the lateral expansion end of the electric telescopic rod 7 is equipped with to be adapted with polygonal column 6 Fixing card 8, the left side of the housing 1, acoustical cotton layer 2 and protective shell 3 is uniformly provided with heat emission hole 9, the shaft 10 it is outer Wall is evenly arranged with permanent-magnet pole 11, and the inner wall of the housing 1 is evenly arranged with the coil windings 12 being adapted with permanent-magnet pole 11.
Wherein, bonded together between the housing 1, acoustical cotton layer 2 and protective shell 3 by adhesive, it is steady to increase connection Qualitative, the protective shell 3 is steel protective shell, and hardness is high, is unlikely to deform, is bonded with and fills out between permanent-magnet pole 11 described in two adjacent groups Item is filled, and the inside of packing is connected with the outer wall of shaft 10, it is more stable when rotating permanent-magnet pole 11.
Operation principle:Shaft 10 and permanent-magnet pole 11 form rotor, and housing 1 forms stator, coil windings with coil windings 12 12 are connected with automobile power source, and coil windings 12 is made to be powered, and stator forms one and power source change cycle phase under the action of electric current Same rotating excitation field, permanent-magnet pole 11 generates induced current under the action of rotating excitation field, while is subject to magnetic in rotating excitation field again The effect of power, so that rotor stress and as requested rotational speed, shaft 10 drives polygonal column 6 to rotate, and polygonal column 6, which drives, to be passed Lever 5 rotates, and when needing to stop self-locking, moment changes the electric current of coil windings 12, and rotating excitation field direction is made to generate variation, from And apply opposite force to rotor, when rotor stops operating, coil windings 12 power off, while power supply is powered for electric telescopic rod 7, Electric telescopic rod 7 promotes fixing card 8 that polygonal column 6 is blocked carry out self-locking, and acoustical cotton layer 2 is used for sound-absorbing, reduces noise, protective shell 3 for protecting the present apparatus, and heat emission hole 9 is used to radiate.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of variations, modification, replace And modification, the scope of the present invention is defined by the appended.
