Abstract
The utility model provides a car electric oil fuel pump using a brushless electric machine, which is characterized in that: a Hall sensor is adopted and thus the turning of the brushless electric machine is realized automatically; the Hall sensor is arranged between a stator and a winding; the axle of a rotator component where a rare-earth permanent-magnet passes through the pump body part and thus the pump impeller is thus driven directly, which makes the low pressure fuel oil flow through the inner part of the electric machine in a high speed and voltage follows from the output. Compared with the prior art, the utility model has the advantages of a high efficiency, reliable performance and safety.
Description
The utility model relates to the attendant equipment of a kind of electro jet car engine fuel supply system.
At present, existing motorcar electric fuel charger mainly is made up of the dc permanent magnet motor and the shell of the pump housing, charged brush, during work, electric current is by installing brush gear and epitrochanterian commutator in the enclosure, the armature loop of flowing through again makes rotor rotation, drives the pump impeller rotation, fuel oil is sucked from import, the motor-drive pump inside of flowing through extrudes from outlet again, and there is following shortcoming in this structure:
1, owing to have mechanical contact between brush and the commutator, relative high-speed motion therebetween causes the two quick wearing and tearing, the service life of having reduced fuel charger.
2, because brush contacts with the commutator that rotates with rotor high-speed, form friction drag, reduced the efficient of electric fuel punp.
3, in the fuel charger work, easily produce electro spark between commutation moment brush and commutator,, might cause firing, make the safety of whole automobile stay hidden danger when a certain proportion of air and gasoline vapor in pump and when depositing.
The purpose of this utility model be intended to overcome prior art not enough and provide that a kind of efficient height, performance are safe and reliable, the motorcar electric fuel charger of long service life, employing brushless motor.
The purpose of this utility model is achieved in that
A kind of motorcar electric fuel charger that adopts brushless motor comprises end cap parts I (1), shell (2), stator and winding (4), pump housing parts (5), pump impeller (6), end cap parts II (7), Hall element (9).It is characterized in that Hall element (9) places in the middle of stator and the winding (4), the axle that the rotor part (3) of rare-earth permanent magnet (10) is installed passes pump housing parts (5) and directly drives pump impeller (6).
Described brushless motor motorcar electric fuel charger, the control mechanism that has adopted Hall element (9) and electronic switching circuit to form goes to realize the commutation of brushless motor.
Described brushless motor motorcar electric fuel charger, the axle of its rotor part (3) passes pump housing parts (5) and directly drives pump impeller (6) rotation, makes low-voltage fuel from motor internal high velocity stream mistake, again from the output of outlet high pressure.
The utility model is described in further detail below by drawings and Examples:
Fig. 1 is a structure cutaway view of the present utility model.
Among Fig. 1,1 end cap parts I, 2 shells, 3 rotor parts, 4 stators and winding, 5 pump housing parts, 6 pump impellers, 7 end cap parts II, 8 electrical outlets, 9 Hall elements, 10 rare-earth permanent magnets.
Principle of work of the present utility model is: working current is linked into stator winding by the electrical outlet of shell, makes stator winding be subjected to electricity to produce magnetic field, and the rotor that has rare-earth permanent magnet produces moment of rotation under the effect of magnetic field force, and then rotates.The switching and the flow direction that the rotor rotation position signal that electronic switching circuit spreads out of according to Hall element changes the stator winding electric current realize the commutation of brushless motor.
Main points of the present utility model are: the motorcar electric fuel charger that adopts brushless motor, the utilization Hall element is realized the commutation of brushless motor automatically, the axle of rotor directly drives the pump impeller rotation, makes low-voltage fuel from motor internal high velocity stream mistake, again from the output of outlet high pressure.
The utility model has the efficient height compared with prior art, dependable performance, safety, service life The advantages such as length are a kind of ideal products that existing automobile has brush direct current drive fuel pump that substitutes.
