Abstract
The utility model discloses a steady formula brushless motor of low noise, including pivot (1), casing (5), rotor (7), stator (8), armature winding (9) be equipped with driver (12) in the pivot and in stator department, this driver is connected with armature winding (9) locate to be equipped with insulating piece (10) on the stator and between stator and driver. The driver is double -deck board -like structure, includes the drive circuit board (19) of jam -proof components and parts between its plywood. The combination of original commutator and carbon brush has been left out in the invention, and its noise is lower, operating stability is high, electrical interference is little, long service life, and the driver radiating effect is good, is favorable to promoting greatly the rotational speed of motor and the precision of regulation and control. But the wide application is more multi -field in office machinery, automatic control, instrument, car etc.
Description
Technical field
The present invention relates to a kind of motor.
Background technology
Motor is generally made up of motor body assembly and deceleration device, wherein: motor body assemblyComprise commutator, carbon brush, armature winding, rotor (being armature core), stator (being magnetic shoe),Casing, rotating shaft (being armature shaft) etc.; Deceleration device comprises that motor output shaft, gear (are snailWheel), deceleration box etc.; Described casing and deceleration box cooperation tighten together, described rotating shaftOne end be snail rod shaped structure, the snail rod shaped structure of this rotating shaft and gear engagement composition worm and gearMechanism's (being deceleration transmission pair). This motor also can be described as brush motor, is applied to civilian garageThe fields such as door, instrument and meter, automobile. Because this motor has the cooperation of carbon brush and commutator,Its noise is higher, operation stability is inadequate, has affected the high rotating speed of motor.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, and provide a kind of without commutator andLower, the stable steady formula brushless electric machine of low noise of noise of carbon brush.
The object of the invention is to realize by following technical solution: the steady formula of low noise is brushless electricityMachine, comprises rotating shaft, casing, rotor, stator, armature winding, in described rotating shaft andLaundry is equipped with driver, and this driver is connected with armature winding, on described stator andBetween stator and driver, locate to be equipped with insulating trip. Described driver is Double-layer plate type structure, its layerBetween plate, include the driver circuit plate of anti-tampering components and parts.
Adopt after structure of the present invention, make rotor produce induction by driver and armature winding and turnMoving, thus drive rotating shaft rotary work, the combination of having removed original commutator and carbon brush,Its noise compared with low, operation stability is high, electrical interference is little, long service life, and driver heat radiationEffective, be conducive to the rotating speed of lifting motor and the precision of regulation and control greatly. Can be widely used inThe more areas such as office machinery, control automatically, instrument, automobile.
Brief description of the drawings
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail.
Fig. 1 is the mounting structure schematic diagram of the steady formula brushless electric machine of low noise of the present invention.
Fig. 2 is the structural representation of driver in Fig. 1.
Detailed description of the invention
Known with reference to Fig. 1, Fig. 2, the steady formula brushless electric machine of low noise of the present invention, comprises rotating shaft1, casing 5, rotor 7 (magnet steel and rare-earth Nd-Fe-B material), stator 8 (silicon steel material),Armature winding 9 (being enamel-covered wire), in described rotating shaft 1 (its periphery) and at stator 8(cover has) driver 12 is equipped with at place, and this driver 12 is connected with armature winding 9, describedOn stator 8 and between stator 8 and driver 12, locate (and stator 8 and drive end bearing bracket 2 itBetween locate) insulating trip 10 (containing insulating tape) is housed.
Wherein, the inside of described driver 12 in casing 5 and directly contacting with rotating shaft,It overlaps 18 by lead-in wire again and is connected with extraneous power supply, and stator 8 is tightly pasted by anaerobism glue-lineIn casing 5; Described driver 12 is Double-layer plate type structure, includes anti-between its doubling plateThe driver circuit plate 19 of chaff element device, have little, the area of dissipation of interference greatly, easily heat radiationAdvantage. In described rotating shaft 1 and at the two ends place of casing 5 (by rolling bearing 4)Drive end bearing bracket 2, rear end cap 17 are housed respectively, between described drive end bearing bracket 2 and rear end cap 17 andBe connected with screw rod 15 (being generally two) near casing 5 places, to be conducive to strengthen motor entiretyFirmness. In described rotating shaft 1 and in the side edge of rolling bearing 4, back-up ring 13 is housed.
As shown in drawings, operation principle of the present invention is: overlap 18 by extraneous power supply by lead-in wireInterior lead-in wire is connected driver 12 and is worked, and makes by driver 12 and the effect of armature winding 9Rotor 7 produces induction and rotates, thereby drives rotating shaft 1 to be rotated work, and stator 8And driver 12, and drive end bearing bracket 2 between the insulating trip 10 located played good insulating effect.
