Technical field
The present invention relates to motor manufacturing technology field, is a kind of brushless, permanently excited direct current motor that adopts the high strength magnetic material to make in rotor assembly.
Background technology
Motor is one of human greatest invention.After motor had been arranged, revolutionary variation had taken place in human being's production, life.Certainly, any motor all is to rely on electric current to produce field drives moment through coil windings and the dynamic power machine that rotates.But in different occasions, different purposes pattern, the power requirement of motor are all had nothing in common with each other, therefore the various motor inventions of a multitude of names are just arranged.If with the power supply classification of input, the branch of interchange, direct current is arranged, can divide single-phase, three-phase again in the interchange; Rated voltage branch with input has high pressure, low pressure; With volume and watt level branch, high-power, middle-size and small-size and electrical micro-machine are arranged; With purposes and use occasion branch plain edition, stepping type, fractional horse-power, servo type, explosion-proof type, submerged type or the like are arranged; With the control mode branch constant velocity type and frequency control type are arranged,, have brushless and the branch of brush is arranged if with the mode branch of electric current input; To make the material branch of rotor, the branch of excitation material and permanent magnetic material is arranged.Till settled the present, still not having a kind of motor at present is the product that comprehensively has above-mentioned various performances.Show according to looking into new data, domestic also less than more powerful permanent magnet DC brushless motor, the brushless electric machine that is used on the automobile start also only being arranged abroad then is the small-power direct current machine, and the non-brush permanent-magnet DC motor that still truly is not applied in the industrial production comes out.Therefore the insider looks forward to the relatively large low-voltage dc brushless motor appearance of power of occasions such as can being used for chemical industry, household electrical appliances, boats and ships, automobile, space flight, motor vehicle; and require its structure simpler; weight is lighter; stepless speed regulation, brushless commutation can not produce spark and overload protection arrangement is arranged.
Summary of the invention
Technical problem to be solved by this invention is the present situation at above-mentioned prior art, a kind of DC motor that does not have brush that adopts permanent magnetic material to make is provided, it has the efficient height, simple in structure, speed adjustable range is wide, non-commutation spark, and design power is relatively large, volume is small and exquisite, advantage in light weight, that manufacturing materials is economized.
The technical scheme that the present invention solves the problems of the technologies described above is: a kind of permanent magnet DC brushless motor, form by motor body, driving and speed regulating device, dedicated connector three parts.It is characterized in that: described motor body is made up of field frame assembly, rotor assembly, bearing, fan blade, end cap, fan housing; Described driving and speed regulating device comprise driving governor, speed-regulating potentiometer and two-direction switch; Described dedicated connector comprises multi-core socket and porous pin.Described field frame assembly comprises that shell, support and installation foot hole, outer casing inner wall are embedded with winding, and is provided with the magneto rotor assembly of its axial rotation relatively in inside.Described rotor assembly comprises rotor body and the rotating shaft that is located at the center, and an end of rotating shaft is located at end cap central authorities by bearing A, and the output of armature spindle then passes the central authorities that bearing B is arranged on the shell seal end face; The rotating shaft of above-mentioned rotor assembly is stretched out outside the end cap, and on the one section axle in the outside of stretching out, be fixed with one the cooling usefulness fan blade, the fan blade outside is covered with a fan housing that fixes with end cap, can prevent the long-time running of motor so effectively and overheated, makes the motor can continuous operation.For the fit clearance between energy self-aligning bearing and the end cap, be provided with a corrugated gasket between above-mentioned bearing A and the end cap the inside.Above-mentioned end cap the inside central authorities are provided with a bearing pedestal, and described bearing A is just ccontaining to be positioned in this bearing pedestal, and the inside, described shell seal end central authorities also are provided with a bearing pedestal, and described bearing B is just ccontaining to be positioned in this bearing pedestal.Adopt aforesaid way bearing A and bearing B more stably can be fixed in the enclosure.But the shell of said stator assembly is provided with the vertical or horizontal fixing installation foot hole of power supply machine, and the end cap of base one end also can be connected with the installation foot hole on the shell during vertical installation.
Be provided with automatic reverse, stepless speed regulation and braking circuit assembly that electronic component and wiring board are formed in the described driving governor, and the subsidiary speed-regulating potentiometer that is provided with; Described dedicated connector comprises multi-core socket and porous plug, they respectively with being electrically connected of power supply, speed-regulating potentiometer, two-direction switch and motor windings, can export three-phase electricity after the direct current frequency conversion of input, drive the rotor rotation.
Compared with prior art, the invention has the advantages that:, need not carry out excitation to rotor, thereby also just save brush and commutator segment because this rotor adopts high-intensity permanent magnet material, be a kind of direct current machine of brushless, realized direct current machine in application than large-power occasions.Therefore this motor does not just need to be provided with in addition commutator, so just do not have the spark that traditional motor produces when commutation yet.Also owing to adopted the Variable Frequency Speed Regulation Principle of brushless electric machine, realize stepless speed regulation, along with the increasing of load, this motor can both keep harder torque in the rated power scope like this; Because of having adopted the magneto rotor assembly, stator winding coefficient height designs closely, so efficiency of motor improves relatively simultaneously; Owing to adopt electronic speed regulation, braking, therefore not only can save mechanical braking mechanism, also reduced noise and mechanical energy consumption, thereby the volume of whole motor is reduced, weight saving, designs simplification.
