Specific embodiment
With reference to specific embodiment, the present invention is described in detail.
A kind of outer coiling group structure of the quiet efficient direct current motor of low frequency, as shown in figs 1-9, including shell 1, described shell 1
It is divided into upper casing 2 and lower casing 3, stator 4 is installed between upper casing 2 and lower casing 3, described stator 4 includes iron core 5 and plastic stent 6, institute
State plastic stent 6 and be divided into upper bracket 7 and lower carriage 8, described iron core 5 is divided into iron core inner core 9 and iron core outer ring 10, upper bracket 7 He
Lower carriage 8 mutually correspondence is plugged in iron core inner core 9, described coil 11 coiling several outer coiling group knots on plastic stent 6
On structure 12, described iron core outer ring 10 is arranged on outside iron core inner core 9, fixes upper bracket 7 and lower carriage 8 and iron core inner core 9, described
Axis hole in the middle of iron core 5 is provided with magnet ring rotor 13, is provided with rotating shaft 14, inside described lower casing 3 in the middle part of described magnet ring rotor 13

Described upper bracket 7 is hollow structure, and its underpart is provided with the card article 16 of corresponding lower carriage draw-in groove.
Described lower carriage 8 is hollow structure, and its top is provided with the draw-in groove 17 of corresponding upper bracket fixture block.
Described plastic stent 6 includes several outer coiling group structures 12, and each outer coiling group structure 12 is by the card article of upper bracket 7
16 and the draw-in groove 17 of lower carriage 8 form.
Described magnet ring rotor 13 is permanent magnet manufacture.
Described upper bracket 7 top is provided with some pin installing holes 18.
Described lower casing 3 bottom is provided with mounting seat 19.
Described iron core inner core 9 is integrally formed manufacture for some slim iron plates.
Described iron core outer ring 10 is integrally formed manufacture for some slim iron plates.
The slot corresponding iron core inner core 9 being formed between each outer coiling group structure 12 and adjacent outer coiling group structure 12 is wherein
The shape of one socket.
Principle is as follows：
It is fixed with annular permanent magnets, the coil that electric current passes through on rotor produces Ampere force, works as rotor inside traditional direct current generator
On coil parallel with magnetic field when, be further continued for turning the magnetic direction that is subject to and will change, therefore the brush transfer of now Rotor terminal
Change piece and replace contact, thus the sense of current on coil also changes, the Lorentz force direction of generation is constant, so motor can keep
One direction rotates.
The operation principle of traditional dc generator is exactly the alternating electromotive force sensing in armature coil, joins by commutator
Close the commutation effect of brush, be allowed to be changed into the principle of direct electromotive force. when brush end is drawn.
The direction of induced electromotive force is pressed the right-hand rule and is determined（Magnetic induction line points to the palm of the hand, and thumb points to conductor motion direction,
The sensing of other four fingers is exactly the direction of induced electromotive force in conductor）.
The direction left hand rule of conductor stress determines.This pair of electromagnetic force defines and acts on one moment of armature, this
Individual moment is referred to as electromagnetic torque in electric rotating machine, and the direction of torque is counterclockwise, and attempt makes armature counterclockwise turn
Dynamic.If this electromagnetic torque can overcome the resistive torque on armature（The resistive torque for example being caused by friction and other load turn
Square）, armature just can rotate counterclockwise.
And this motor changes traditional rotor and stator, using permanent magnet as rotor, to design whole motor, by electromagnetism
Induction coil, as stator, has overturned traditional direct current generator, creates stable rotating excitation field, so that this motor is worked smooth,
Start the new page of DC. machine design, its conversion ratio is more preferably, more quiet, more efficient.
This motor need not be complicated control program auxiliary it is not necessary to additionally install controller it is possible to normal work, its
Bright point is without multisection type or multiphase（A phase, B phase, C phase etc.）Baroque auxiliary it is possible to normal work.
Magnet ring rotor 13 top and bottom are both provided with annular groove.
If stepper motor controls improper easy generation to resonate；It is difficult to run to higher rotating speed, meanwhile, when slowly running
Vibration and noise are greatly its intrinsic shortcomings, cannot solve so far and overcome, and need with the use of expensive sensor with
And as optical encoder feedback device, use and bother very much.
If converted to AC servo motor, vibrations and noise almost can be overcome completely, but relatively costly, user
It is difficult to bear.
Above-mentioned embodiment is the preferred embodiments of the present invention, is not for limiting the enforcement of the present invention and right model
Enclose, equivalence changes and modification that the content described in all foundation the present patent application scopes of patent protection is made, all should be included in this
In patent application the scope of the claims.
