Technical field
The invention belongs to a kind of brushless, permanently without Hall Double magnetic circuit motor technical field, refer to a kind of single group magnetic sheet axial double magnetic circuit permanent magnet DC motor especially.
Background technology
Conventional direct current permanent magnet motor as shown in Figure 1, be radial magnetic circuit, only has one group of winding 2, magnetic circuit enters from the magnetic sheet 1, N pole on stator 3 to adjacent S pole magnetic sheet 1, and form radial magnetic circuit, the winding 2 of this motor forms with the copper wire winding of circular section, so the tankful rate of winding 2 only has about 75%, make that motor size is large, Heavy Weight, motor shaft 5 thick, peak efficiency only has 80 ~ 84%, and during coil working on center roller 4, heating is also difficult to shed.
Separately there is one " brushless, permanently is without Hall axial double magnetic circuit direct current machine " (application number CN2011205611111) as shown in its patent announcement document, see accompanying drawing 2: the present invention relates to technical field of motors, it comprises housing 1, stator core 2, wire 3, locknut 4, winding coil 5, magnetic links 6, stator core support 7, bearing 8, dead axle 9, yoke 10 and front and rear cover 11; Housing 1 both sides are provided with front and rear cover 11, center is equipped with dead axle 9 to front and rear cover 11, front and rear cover 11 is provided with bearing 8 with the junction of dead axle 9, dead axle 9 is fixed with stator core support 7 by locknut 4, stator core support 7 is fixed with stator core 2, stator core 2 arranged outside has winding coil 5, is provided with yoke 10 inside front and rear cover 11, yoke 10 is evenly arranged magnetic links 6, dead axle 9 has been equipped with wire 3.It utilizes magnet steel to the full extent and makes full use of the object that motor space has reached maximum Energy Efficiency Ratio, thus achieves the object of few material, small size, high-power, high energy efficiency.
And " a kind of axial double magnetic circuit high power direct current machine " (application number CN2008100529734) is as shown in its patent announcement document, see accompanying drawing 3: this invention provides a kind of axial double magnetic circuit high power direct-current motor, this electric motor structure comprises front end housing 1, rear end cap 10 and central shaft 6, central shaft 6 is connected with the armature winding 2 of multiple winding composition; By trip bolt, yoke is separately fixed at the inner side of front end housing 1 and rear end cap 10, yoke is fixed with the mutually corresponding equally distributed magnet of polylith; In the gap of the adjacent winding of armature winding 2, embed the built on stilts iron core forming two flux circuits, rear end cap 10 is provided with by the fixing multiple equally distributed brush 15 of compression spring 19, the surface that brush 15 is close to armature winding 2 contacts.Effect of the present invention is that this structure has broken the design theory of conventional DC motor, makes motor volume little, few with material, and the power that motor exports is close to identical with conventional motor, reduces manufacturing cost.The direct current machine of various different capacity can be produced, for the fields such as aviation, military equipment, electric automobile, high speed electric motorcycle, electric motorcycle ship provide good power source.Above-mentioned two kinds of motor shortcomings introduced have two groups of magnetic sheets equally, and winding is difficult to heat radiation in centre, directly affect the stability of its performance.And the latter also add brush, not only make that volume increases, complex structure, and easily to produce after spark, wear of brush loose contact when using and need the problems such as often replacing.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, and a kind of single group magnetic sheet axial double magnetic circuit permanent magnet DC motor is provided.
The present invention includes stator, iron core, armature winding, by shaft-driven rotor, magnetic sheet, shell, end cap, two groups of armature windings are separately fixed at two side ends and cover, and wound core is arranged, described shell, iron core, armature winding form stator; The winding easily generated heat is fixed on the shell of motor, has formed stator.
Described magnetic sheet is coated on the rotor in the middle of motor and forms yoke, and rotor plugs in the stator, magnetic sheet and iron core parallel.Because all there is flowing to of the magnetic line of force on the two sides of N/S pole magnetic sheet or flows out, therefore create axial double magnetic circuit.
Described outer side be coated with annular, with the cooling jacket of iron core parallel.Cooling jacket can carry out forced water cooling to motor effectively.
Beneficial effect of the present invention is: 1. the technical program overcomes the loose and inefficient shortcoming of customary DC motor; 2. the price overcoming " brushless, permanently is without Hall axial double magnetic circuit direct current machine " scheme is high, the shortcoming of weak heat-dissipating, decrease in efficiency; 3. overcome " a kind of axial double magnetic circuit high power direct current machine " price is high, weak heat-dissipating, unstable properties, need the shortcoming of brush and periodic maintenance; 4. this motor scheme copper factor is up to 98%, and efficiency is more than 90%; 5. this programme material is few, compact conformation, price are low; 6. good cooling results, motor performance is reliable and stable, the life-span is long.
