Description
Technical field
the utility model relates to DC motor technology field, and specifically one is mainly used in automobile power back door strut direct current permanent magnet motor.
Background technology
Common direct current permanent magnet motor is applied on electric tail gate strut, the rotor core adopted is conventional structure and flute profile, and magnetic steel material selects ordinary ferrite material, cause conventional DC magneto and be applied on this product that not only output torque is little, motor volume is large, waste material, and because need the rotating speed of motor to accomplish very highly also cause its running strenuous vibration and then create huge noise, not only be detrimental to health, also have impact on the useful life of motor.If needing to reach the moment of torsion that strut normally starts to adjust with regard to needing the speed ratio increasing decelerator, so not only adding the cost of use, and increase the noise of decelerator and lower efficiency.In view of this, be necessary to provide a kind of direct current permanent magnet motor exporting high pulling torque.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of direct current permanent magnet motor, reduces motor volume, increases output torque, reduces the noise of motor and extends the useful life of motor.
In order to solve the problems of the technologies described above, the utility model takes following technical scheme:
A kind of direct current permanent magnet motor, the rotor comprising end cap, stator and be located in stator, end cap is installed in stator one end, described stator comprises shell, be located at the magnet steel of this outer casing inner wall and be located at this outer shell outer wall protect magnetosphere; Rotor comprises rotating shaft and is fixed on the rotor core in this rotating shaft, rotating shaft is fixed with commutator, is wound with winding in rotor core; End cap comprises the iron covering being contained in shell one end and the bearing be sleeved in rotating shaft, and iron covering is equipped with carbon brush holder, and this carbon brush holder is provided with carbon brush arm and electrical terminals, and this carbon brush arm is provided with carbon brush; Winding is connected with commutator and conducts electricity, and commutator and carbon brush sliding contact are conducted electricity.
The shell of described stator is also equiped with the catapult for fixing magnet steel.
The magnet steel of described stator adopts neodymium iron boron material to make.
Described rotor core surface spraying has insulating barrier.
The shell of described stator is metal shell.
The utility model effectively reduces motor volume, and the magnet steel of word is selected neodymium iron boron high-performance material, and effectively reduce the noise of motor and extend the useful life of motor, improve the efficiency of motor, structure is simple, function admirable.Under equal volume, moment of torsion doubles, and has brought up to 0.25N.M from 0.12N.M, and the utility model motor is particularly useful on electric tail gate strut.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model cross-sectional view;
Accompanying drawing 2 is the I--I cutaway view in accompanying drawing 1.
Embodiment
For the ease of the understanding of those skilled in the art, below in conjunction with accompanying drawing, the utility model will be further described.
As shown in figure 1 and 2, the utility model discloses a kind of direct current permanent magnet motor, the rotor comprising end cap, stator and be located in stator, end cap is installed in stator one end, described stator comprises metal shell 3, be located at the magnet steel 1 of this metal shell 3 inwall and be located at this metal shell 3 outer wall protect magnetosphere 4; The rotor core 2 that rotor comprises rotating shaft 15 and is fixed in this rotating shaft 15, rotating shaft 15 is fixed with commutator 9, is wound with winding 6 in rotor core 2; End cap comprises the iron covering 8 being contained in metal shell 3 one end and the bearing 10 be sleeved in rotating shaft 15, iron covering 8 is equipped with carbon brush holder 14, and this carbon brush holder 14 is provided with carbon brush arm 13 and electrical terminals 12, and this carbon brush arm 13 is provided with carbon brush 7; Winding 6 is connected with commutator 9 and conducts electricity, and commutator 9 and carbon brush 7 sliding contact are conducted electricity.Metal shell 3 is also equiped with the catapult 5 for fixing magnet steel 1, this catapult 5, for being tightened up by magnet steel 1, ensures the stability of magnet steel 1.Rotor core 2 surface spraying has insulating barrier 11, and this insulating barrier 11 is formed by the insulating powder being sprayed on rotor core surface.
In addition, the magnet steel 1 of stator adopts neodymium iron boron material excitatory, can improve the power density of motor, in same volume situation larger than common direct current permanent magnet motor output torque 2 times, motor output torque is large, motor volume is little, the rotating speed of motor can accomplish very lowly just can meet torque demand, and rotating speed is low can reduce the noise of motor and extend the useful life of motor, and efficiency that power density is high and generating heat is due for promotion all mutually, its structure is simple, function admirable.And carry out space increasing for the groove installing winding in rotor core, more enamelled wire excitation can be admitted of.
It should be noted that, the above is not the restriction to technical solutions of the utility model, and under the prerequisite not departing from creation design of the present utility model, any apparent replacement is all within protection range of the present utility model.
