Specific embodiment

This utility model is described in detail with reference to specific embodiment.

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, the 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, the stator 4 includes iron core 5 and plastic stent 6, institute It is upper bracket 7 and lower carriage 8 to state 6 points of plastic stent, and 5 points of the iron core is iron core inner core 9 and iron core outer ring 10, the He of upper bracket 7 The mutually correspondence of lower carriage 8 is plugged in iron core inner core 9, several the outer coiling group knots of the coiling of the coil 11 on plastic stent 6 On structure 12, the 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, and the middle part of the magnet ring rotor 13 is provided with rotating shaft 14, the inner side of the lower casing 3 Control board 15 is installed, the control board 15 is electrically connected with coil 11.

The upper bracket 7 is hollow structure, and its underpart is provided with the card article 16 of correspondence lower carriage draw-in groove.

The lower carriage 8 is hollow structure, and its top is provided with the draw-in groove 17 of correspondence upper bracket fixture block.

The plastic stent 6 include several outer coiling group structures 12, each outer coiling group structure 12 by upper bracket 7 card article 16 and the draw-in groove 17 of lower carriage 8 constitute.

The magnet ring rotor 13 is permanent magnet manufacture.

The top of the upper bracket 7 is provided with some pin installing holes 18.

The bottom of the lower casing 3 is provided with mounting seat 19.

The iron core inner core 9 is integrally formed manufacture for some slim iron plates.

The iron core outer ring 10 is integrally formed manufacture for some slim iron plates.

The corresponding iron core inner core 9 of slot 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：

Traditional direct current generator the inside is fixed with annular permanent magnets, and electric current produces Ampere force by the coil on rotor, when When coil on rotor is parallel with magnetic field, the magnetic direction for being further continued for turning to be subject to will change, therefore the now brush of Rotor terminal Alternately contact with conversion sheet, so as to the sense of current on coil also changes, the Lorentz force direction of generation is constant, so motor energy A direction is kept to rotate.

The operation principle of traditional DC generator is exactly, the alternating electromotive force sensed in armature coil, to match somebody with somebody by diverter The commutation effect of brush is closed, is allowed to from brush end be changed into the principle of direct electromotive force. when drawing.

The direction of induction electromotive force determine by the right-hand rule (magnetic induction line points to the palm of the hand, and thumb points to conductor motion direction, Other four sensings for referring to are exactly the direction of induction electromotive force in conductor).

The direction of conductor stress is determined with left hand rule.This pair of electromagnetic forces are defined and act on one torque of armature, this Individual torque is referred to as electromagnetic torque in electric rotating machine, and the direction of torque is that counterclockwise, attempt makes armature counterclockwise turn It is dynamic.If this electromagnetic torque can overcome resistive torque (such as resistive torque for being caused by friction and other loads turn on armature Square), armature just can rotate counterclockwise.

And this motor changes traditional rotor and stator, permanent magnet is designed into whole motor as rotor, by electromagnetism Induction coil has overturned traditional direct current generator as stator, generates stable rotating excitation field, makes the work of this motor smooth, The new page of DC. machine design is started, its conversion ratio is more preferably, more quiet, more efficient.

This motor is without the need for 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 the baroque auxiliary of multiphase (A phase, B phase, C phase etc.), it is possible to normal work.

The top of magnet ring rotor 13 and bottom are both provided with annular groove.

If improper easy generation of motor control is resonated；It is difficult to run to higher rotating speed, meanwhile, when slowly running Vibration and noise are its intrinsic shortcomings greatly, cannot solve so far and overcome, and need with the use of expensive sensor with And the feedback device as optical encoder, use and bother very much.

If converted to AC servo motor, almost can completely overcome vibrations and noise, but relatively costly, user It is difficult to bear.

Above-mentioned embodiment is preferred embodiment of the present utility model, is not for limiting enforcement of the present utility model The equivalence changes made with interest field, all contents according to described in this utility model patent protection scope and modification, All should be included in this utility model claim.
