Abstract

The utility model relates to an improved motor structure, consisting of printing circuit boards, a casing, an axes magnet and a bearing; two printing circuit loops consisting of printing circuit boards are arranged in the utility model, a through hole is arranged at the centre of the two printing circuit boards, and after the axes passes through the through hole, a magnet is covered and fixed between the two circuit boards, two ends of the axes is sleeved in the bearing, and the structure above is fixed in the casing; when the printing circuit loop is electrified, producing a magnetic field to induce the magnet backwards and forwards, the magnet rotates so as to make the axes rotate subsequently.

Description

The electric motor structure improvement

Technical field

The utility model relates to mechanical, and particularly a kind of electric motor structure improvement refers to that especially a kind of induction effect by form printed circuit coils and magnetic patch winds the line trouble to reduce manufacturing cost, the motor of minimizing volume weight to constitute rotation, to exempt.

Background technology

As everyone knows, general electric motor structure is normally behind the steel wire of the suitable number of turns of coiling on the silicon steel sheet, constitute a coil, make coil place the shell inner edge, wear a rotor in hub of a spool again, behind coil electricity, produce a magnetic field, with inductiopn rotor it is rotated, the motor that this kind is common is because the coiling of coil quite bothers, not only processing procedure efficient is low, failure rate is also high, and the weight heaviness of whole motor, big, also high, the many shortcoming of cost of volume are suddenly treated and should be improved.

The utility model content

According to the purpose of this utility model, at many shortcomings that above-mentioned common motor exists, provide a kind of electric motor structure improvement, make it to have simple, in light weight, the advantages such as volume is little, low cost of manufacture of making; Its structure is to be provided with two printed circuit board (PCB)s, copper case by this circuit board is made form printed circuit coils, and be provided with an open-work in the center of this circuit board, two circuit boards are fixed in the casing, and after an axle center is worn by the open-work of circuit board, between two circuit boards, wear and fix a magnet, and make the two ends, axle center be placed on bearing, when form printed circuit coils in the energising after, produced a magnetic field to respond to the magnet of its front and back ends, make magnet produce rotation, and then make the axle center constitute rotation; The motor of this structure wherein is located at the magnet of form printed circuit coils front and back ends, be for multipole to arrangement, side's property magnet such as promptly N, S be tactic.

Embodiment

As accompanying drawing 1 to shown in the accompanying drawing 3, the utility model is made of printed circuit board (PCB) 1, casing 2, axle center 3, magnet 4, bearing 5, wherein, two printed circuit board (PCB)s 1 are to make form printed circuit coils 11 by the Copper Foil of this two printed circuit board (PCB) 1, and be provided with an open-work 12 in the center of this two printed circuit board (PCB) 1, this two printed circuit board (PCB) 1 is locked in the casing 2 with stator 13; The circle footpath in axle center 3 is slightly less than the open-work 12 of printed circuit board (PCB) 1, after its open-work 12 is worn, be nested with fixed magnet 4 between this two circuit board 1, present embodiment is to adopt most N, the S utmost point to direction magnet such as tactic, and makes the two ends in this axle center 3 be placed on casing 2 forward-and-rearward bearings 5; After printed circuit board (PCB) 1 set form printed circuit coils 11 is switched on, produced the magnet 4 of a magnetic field to respond to its two ends, make magnet 4 produce rotation, and then axle center 3 is rotated;

As shown in Figure 4, in use, switch on by the form printed circuit coils 11 that two printed circuit board (PCB)s 1 are printed, make it produce a magnetic field, by the magnet 4 of magnetic field induction in the centre and since magnet 4 be multipole to arrangement, so can produce rotation, rotate relative to driving axle center 3, to be provided as the effect of transmission.

Advantage of the present utility model, the one, owing to do not need can reduce processing procedure in the silicon steel sheet coiling, Reduce cost of manufacture and material; The 2nd, owing to do not use silicon steel sheet and intensive coil, make whole motor Weight be minimized, its volume is also reduced.

Claims

1, a kind of electric motor structure improvement is characterized in that: be provided with two printed circuit board (PCB)s, make form printed circuit coils by the Copper Foil of this printed circuit board (PCB), and be provided with an open-work in the center of this two printed circuit board (PCB), this circuit board is fixed in the casing; Its circle footpath, one axle center is slightly less than open-work of printed circuit board (PCB), wear open-work after, between two printed circuit board (PCB)s, be nested with and fix a magnet, and make the front and back ends in axle center be placed on the forward and backward side's of casing bearing.

2, according to the described a kind of electric motor structure improvement of claim 1, it is characterized in that: the said magnetic patch of being located in the middle of two form printed circuit coils, be for etc. direction magnet.
