Description of drawings
Accompanying drawing is the whole decomposition analysis figure of minitype iron core motor of the present invention
Specific embodiment
Minitype iron core motor of the present invention is made up of three parts: stator module, rotor assembly and end cap 18 assemblies; As scheme institute and look.Stator module comprises an oval casing 6, and described oval casing 6 is that an elongated cylinder is excised a part 8 along the extension of central horizontal direction and in casing 6 both sides along the central horizontal direction, makes it form the oval casing 6 with inner space.Described inner space is equipped with two tile magnet steel 3a, 3b, and tile magnet steel 3a, 3b are that a N is extremely inside, and one is that S is extremely inside.Described oval casing 6 one ends are opening shape, the other end is a column 5, described column 5 is to extend a part on the step-like extension of oval casing 6 one ends again, make it form an inner space concentric with oval casing 6, described inner space is equipped with oiliness bearing 4.
Rotor assembly comprises: a central shaft 13, be installed in the some iron cores 10 on the central shaft 13, and described iron core 10 is become certain shape and the mode by riveting to become as a whole by punching out.Described iron core 10 be shaped as three "T"-shaped, three "T"-shaped is to become 120 degree around a center; Described three "T"-shaped be on a circular face, to form by cutting, and therein heart place link to each other form as a whole.Coil (not shown): around "T"-shaped iron core 10, the method of its rich system should be followed such rule: be the center with some "T"-shaped iron cores 10 promptly, perpendicular with the center of some "T"- shaped iron cores 10, and 10 one-tenth 120 degree of some "T"-shaped iron cores that are adjacent.Commutator segment 11: be generally three, an end that contacts with brush 15a, 15b is for semicircle, and the other end is a pad 12.The mode of its combination should be followed such rule: promptly the angle between the rectification sub-member of being made up of three commutator segments 11 is 120 degree, and becomes a complete rotor assembly by injection molding way and piezo-resistance 9, central shaft 13.Described coil should connect like this: promptly top the end of a thread of coil links to each other with pad 12 on the commutator segment 11, and terminal stub links to each other with another pad 12 on the commutator segment 11.Circulation can be formed a complete circuit thus successively.
As mentioned above, rotor assembly is installed in the stator module, then end cap 18 is installed to the opening portion of stator module, makes commutator segment 11 sliding contacts on brush 15a, 15b and the rotor assembly simultaneously.Thus, external power source is entered by electrode 17a, 17b, to brush 15a, 15b, arrives coil through commutator segment 11 through electric conductor 14 then, makes coil produce magnetic field.Because iron core 10 is the material by the high permeability of multiple-piece, the eddy current that magnetic field is produced reduces, thereby greatly improved the intensity in magnetic field, the high-intensity magnetic field that consequent high-intensity magnetic field and stator module upper magnetic steel 3a, 3b produce interacts, rotor assembly is rotated, and this rotation will be delivered on the needed electronic instrument by central shaft 13.
Because the magnetic field that iron core 10 is produced is more much better than than the magnetic field that existing drag cup motor produces, thereby can produce much better than actuating force, can thus be the motor that electric devices such as shaver, toy car, electric toothbrush provide a kind of high drive.
In addition, iron core 10 of the present invention can be installed accurately by the anchor point on the iron core 10 7, because iron core 10 is to be shaped by punching out, thereby its machining accuracy guarantees easily, thereby can between iron core 10 and magnet steel 3a, 3b, keep the minimum close gap of magnetic, accomplish maximum actuating force.
Also have, because casing 6 of the present invention is to excise a part 8 along the extension of central horizontal direction and in casing 6 both sides along the central horizontal direction in elongated cylinder, thereby reduced the volume of motor effectively, thereby can in the structure of motor miniaturization, have better installing space.
In another embodiment of the present invention, front end at minitype iron core motor of the present invention, an oscillator 2 also is installed, described oscillator 2 is cylindrical balancing weights, described cylindrical balancing weight excises from the center line horizontal direction, and outside the center line vertical direction, extending a part by centre bore 1 part, described oscillator 2 is by iron or the density material bigger than iron.Be appreciated that oscillator 2 links to each other with the central shaft 13 of minitype iron core motor by centre bore 1.When the central shaft 13 drive oscillators 2 of minitype iron core motor rotate, because the off-centre of oscillator 2 weight, thereby in rotation, can produce bigger vibration force, can be delivered to this vibration force on the electronic instrument that the minitype iron core vibrating motor is installed thus, thereby can play the vibromassage effect, or remind the user who carries electronic instrument that the external information incoming call is arranged.
In above-mentioned two embodiment of the present invention, piezo-resistance 9 links to each other with rectification sub-member, coil.When electric current passed through said elements, piezo-resistance 9 can effectively reduce the pulse characteristic of electric current, thereby the commutation spark of commutator segment inter-module is reduced.This has reduced the electromagnetic interference of motor on the one hand; Improved the useful life of motor on the other hand.
In sum, the advantage that the present invention has existing drag cup motor to be difficult to have, clear although the present invention has set forth by the above embodiments, can on institute's content do suitable adjustment, the scope of its adjustment is with in the protection scope of the present invention of will going into.
