Description
Technical field
The utility model relates to a kind of micromachine, specifically a kind of efficient and long life micromachine.
Background technology
Along with scientific and technical development, people are more and more higher to the requirement of living standard quality, the demand that can realize automation to some articles for daily use is strong all the more, therefore the various household products of intelligent automaticization constantly enters in the middle of people's daily family life, the central also requisite application that be unable to do without various motor products.And wherein, for hypomegetic household products, for example shaver, toothbrushes etc. are as realized the functions such as automatic motion, because being subject to the impact of dimensional structure, motor can not do too much, and therefore miniaturization and the long-life requirement for satisfied long-term use have had to mention the position standing in the breach, and therefore develops a kind of not only miniaturization but also long motor active demand especially of life-span.
Chinese patent once disclosed the micromachine (CN201210023404) that a kind of outer diameter D A is less than/equals 6mm, the magnet rotor that this micromachine comprises the stator of the hollow cylinder shape with stator winding and arrange in the mode that can rotate around rotating shaft by means of armature spindle in stator.Described stator winding can be controlled according to the position of rotation of magnet rotor, to produce magnetic rotation transition.For surveying the position of rotation of magnet rotor, in the region that the end face axial of that in the plane perpendicular to rotating shaft and described magnet rotor is adjoined, settle a sensor chip that comprises at least one magnetic field sensor, to make the magnetic field of described magnet rotor can be applied on described magnetic field sensor, thereby can analyze to determine to magnetic field the position of rotation of rotor.
Utility model content
The utility model object is to provide a kind of a kind of efficient and long life micromachine for small-sized household electronic products such as high-end shaver, toothbrushes.
For achieving the above object, the solution that the utility model is taked is: a kind of efficient and long life micromachine, it comprises casing, bonnet, brush, axle, casing is metal shell, its cross section is circular structure, magnet steel is also the hollow tubular structure of circular cross-section, magnet steel packs in casing and contacts with casing inner wall, in bonnet, be pressed into bonnet bearing, brush is contained in bonnet, casing bearing is contained in casing front end, axle is anterior through casing bearing, upper coil and the chip installed in axle middle part, axle is installed commutator on rear portion, piezo-resistance, piezo-resistance and coil electrically contact, windmill before also installing respectively on axle front and rear part, rear windmill, bonnet is combined with casing.
For reduce the volume of motor housing as far as possible, save footprint, the cross section of described metal shell is circular structure, has processing simple, the feature that cost is low simultaneously.Described permanent magnet is also the hollow tubular structure of circular cross-section, makes overall Distribution of Magnetic Field more reasonable, selects more efficient magnetic material simultaneously, is equipped with the better core material of magnetic conduction simultaneously.On motor conduction and anti-wear performance, proprietary application better commutation material composition, commutation material based on motor in the past containing on the basis of palladium element, increase into micro-rare earth material composition, stability to motor and being all significantly improved on useful life, thereby reach the Integral lifting in the performance of motor, windmill before simultaneously also installing respectively on axle front and rear part, rear windmill, play air-cooled effect, after tested, motor can be enhanced about more than once useful life, both realized miniaturization, there is again long feature of life-span, be applicable to high-end shaver, the small-sized household electronic products such as toothbrush, the demand of the daily life of more fitting.
