[detailed description of the invention]
Below in conjunction with accompanying drawing, the structure of this electric rotating machinery apparatus is described in detail:
Fig. 1,2 explanation:
Referring to Fig. 1, shown in 2, illustrate this electric machine and be mainly made up of rotating module and stuck-module, couple can relatively rotate by bearing between them。Wherein rotating module includes the medium ring 2 that adopts soft magnetic materials, and closely knit winding with the fixing conductive coil 6 of binding agent on medium ring 2。
Stuck-module includes the ndfeb magnet 4,5 of internal ring 1, outer shroud 3, and annular, and magnetic piece 4 binding agent or other suitable mode are fixed on the outside of internal ring 1, and magnetic piece 5 binding agent or other suitable mode are fixed on the inner side of outer shroud 3；Such magnetic piece 4 and 5 is positioned opposite across medium ring 2 and conductive coil 6 thereof, this makes the both sides of conductive coil 6 be between described magnetic piece 4 and magnetic piece 5 and medium ring 2 in the annular radial magnetic gap formed, the magnetic direction of magnetic piece 4 and magnetic piece 5 is along circular radial direction the trend being perpendicular to conductive coil 6, namely sense of current。
Except above-mentioned component, the other parts of described motor also include: interior ring support 7, middle ring support 8, housing 9, axle 10, input/output axle 11, rolling bearing 12, brush 13。Outer shroud 3 is assemblied on housing 9, and axle 10 is supported internal ring 1 by interior ring support 7 and is fixed together with housing 9, is actually a part for stuck-module；Medium ring 2 supports on the mandrel 10 by middle ring support 8, rolling bearing 12, in simultaneously, ring support 8 couples with input/output axle 11 again, input/output axle 11 also with roller bearings on housing 9, therefore input/output axle 11 is as the ingredient of rotating module, carries outside output motor moment of torsion or provides the function of power to motor；Brush 13 is fixed on middle ring support 8 or axle 11, it is ensured that power or export its electric power to when whole system high speed rotating hot-wire coil 6。
Specific embodiment 1:
The radial direction that air-gap magnetic field direction is circle that above-mentioned magnetic piece 4 and magnetic piece 5 are formed with medium ring 2, relation between magnetic piece 4 and the magnetic direction of magnetic piece 5 that described medium ring 2 both sides are positioned opposite can have two kinds of selection schemes: the first is that the magnetic direction of both sides magnetic piece 4 positioned opposite and magnetic piece 5 repels each other on the contrary, and the second is that both sides magnetic piece 4 positioned opposite is identical with the magnetic direction of magnetic piece 5 attracting。Introduce separately below:
First the first scheme is described。Now magnetic piece 4 with 5 across the magnetic direction of medium ring 2 be relative mutual exclusion, namely contrary；For strengthening the magnetic induction of air gap between medium ring 2 and both sides magnetic piece 4 and magnetic piece 5, magnetic piece 4 and magnetic piece 5 adopt high performance ndfeb magnet, medium ring 2 adopts the soft magnetic materials of high magnetic permeability, and the gap between medium ring 2 and magnetic piece 4 and magnetic piece 5 is little as much as possible under discontiguous premise between maintenance magnetic piece 4 and magnetic piece 5 and conductive coil 6；When the conductive coil 6 being enclosed within outside medium ring 2 is energized, the sense of current in conductive coil 6 in magnetic field, medium ring 2 both sides is contrary, and the direction in magnetic field, both sides is also contrary。So according to Ampere law, magnetic field, both sides gives the active force of conductive coil 6 and is precisely circumferentially and in the same direction, the amplitude of active force is directly proportional to current intensity, and direction changes with sense of current change；Material is thus formed a magnetic field force pure torsion, its numerical value should produce force of periphery sum in magnetic field, both sides equal to conductive coil 6 and be multiplied by the radius of medium ring center line；This moment of torsion outwards exports offer power by input/output axle 11。
Now briefly describe first scheme。Now magnetic piece 4 and 5 across the magnetic direction of medium ring 2 be attracting, but owing to the conductive coil 6 current in wire in magnetic piece 4 magnetic field and the current in wire in magnetic piece 5 magnetic field are reverse, so the force of periphery that described conductive coil 6 produces in magnetic field, both sides is reverse, the moment of torsion that such conductive coil 6 produces should be equal to the circumference electromagnetic force of this conductive coil 6 side and be multiplied by the width between conductive coil 6 both sides。
Foregoing is for the situation of motor output torque。And described technology can be used for electromotor, now power source drives input/output axle 11 to rotate, and causes conductive coil 6 cutting magnetic line in magnetic field, thus producing induction electromotive force in conductive coil 6 to the external world for electric energy。
Specific embodiment 2:
Below in conjunction with accompanying drawing 3,4, the structure of this mobile form of device is briefly introduced:
Stuck-module includes pedestal 14, and arrangement is fixed on the Magnet 16 on pedestal 14；Mobile module includes the soft magnetic material component 15 being wound with conductive coil, by drive member (or drive member) 17, soft magnetic material component 15 and by the connecting rack 18 between drive member (or drive member) 17, and brush 19 on mount 18 is installed。
The electromagnetism operation principle of described device is similar with described by specific embodiment 1, in this just not repeat specification。
When coil passes into electric current, under the influence of a magnetic field, the mobile module at coil place is subject to the driving of magnetic field force, and the orientation along Magnet 16 is moved；
When mobile module is subject to extraneous driving and moves along the orientation of Magnet 16, due to coil cutting magnetic line, coil just produces induction electromotive force, thus outside output power。
The effect of brush 19 is to ensure when coil moves with mobile module to coil power supply or output power therefrom。
It is above the description of this invention and non-limiting, based on other embodiment of inventive concept, all among protection scope of the present invention。
