Description

A kind of electric machine

Technical field

The utility model relates to a kind of electric machine, refers to a kind of electric machine with plate coil especially.

Background technology

Motor extensively applies to people's various fields in life, and for example treadmill, water pumper, toy car, water plug, rain brush control motor etc. are example with traditional direct current brush motor; It mainly comprises stator and two assemblies of rotor (or armature); Stator is generally permanent magnet, and rotor is generally electromagnet, often coats silicon steel sheet with enamelled wire; Be attached to and hold upward composition of axle, the principle that electromagnet and permanent magnet magnetic are repelled each other after energising by this drives rotation.

Yet; The quantity that coil twines directly has influence on the power of motor; But when increasing coil quantity or density, inevasiblely make the winding of coil increase the overall volume of motor, and have that cost is higher, manufacturing process is difficult for simplification, shortcoming such as noise, power consumption are many; Therefore, need a kind of electric machine that can dwindle winding volume and improve above-mentioned shortcoming.

Summary of the invention

For solving above-mentioned technical disadvantages; The main purpose of the utility model is to provide a kind of electric machine with plate coil; This electric machine; Comprise the plate coil that is placed in upper shell cover, the lower cover relative and be welded in two brushes in this lower cover, and be placed in the stator department in this lower cover with upper shell cover, wherein:

Said plate coil is a ring-type, has first opening;

Said upper shell cover has the axle of holding, sheathed this plate coil;

Said lower cover has the circular hole that holds axle with respect to said;

Said brush, the said upper shell cover direction of court is welded in this lower cover and contacts with said plate coil, and

Said stator department is placed in the said lower cover, has and said first opening and the second coaxial opening of said circular hole.

Said plate coil comprises several first circuits, places the upper strata of this plate coil and the lower floor that several second circuits place this plate coil.

Said first circuit and said second circuit are separated with insulating barrier.

First circuit of said plate coil and second circuit are to distribute with straight line.

First circuit and second circuit of said plate coil are with curve distribution.

The characteristics of the utility model are; Utilize plate coil can make the mode panelized of coil winding originally; And can use existing perfect circuit board process mode to make, can reduce cost of labor, equipment cost and processing procedure cost significantly, more can reduce volume, increase rotary speed and the torsion of electric machine; More because whole space adaptation is high; And can reach the effect of waterproof, can apply to widely among the various fields now, so that electric machine can reach good result compact and that efficient is higher.

Embodiment

Below in conjunction with accompanying drawing the execution mode of the utility model is done more detailed explanation, make and have the knack of this art and after studying this specification carefully, can implement according to this.

See also shown in Figure 1; The electric machine of the utility model (100) comprises plate coil (10), upper shell cover (20), lower cover (30), two brushes (40); And stator department (50); Have in the said upper shell cover hold the axle (21), said plate coil (10) be a ring-type, and with first opening (11) be sheathed on said hold the axle (21) on and be placed in this upper shell cover (20); Said lower cover (30) and said upper shell cover (20) are relative, and have a circular hole (31) and hold axle (21) and mutually combine with respect to said; Said two brushes (40) are welded in the said lower cover (30); And contact with this plate coil (10) towards the direction of this upper shell cover (20); And be connected with the both positive and negative polarity (not shown) of external power source respectively, in addition, comprise an elastic parts (not shown) in the said brush (40) to keep and the fixing contact height of plate coil (10); Avoid influencing the rotation of plate coil (10), also avoid wearing and tearing brush (40) and plate coil (10); Said stator department (50) is an annular permanent; Be placed in the said lower cover 30; And have and said first opening 11 and coaxial second opening (51) of said circular hole (31); When assembling, to be respectively first opening (11) of plate coil (10), second opening (51) of stator department (50) and the circular hole (31) of lower cover (30) along said order of holding axle (21) from top to bottom.

See also shown in Figure 2; Plate coil (10) comprises several at first circuits (12) on upper strata and at second circuit (13) of lower floor, and with insulating barrier (not shown) separation, and first circuit (12) and second circuit (13) are processed for metal material between this first circuit and this second circuit; Be connected with second end points (15) at first end points (14) respectively; Thereby make circuit be connected to continuous coil, in the utility model embodiment, said first circuit (12) and second circuit (13) distribute for straight line.
