Abstract
The invention discloses a brushless electrical motor fuel pump with inner controller, which comprises an oil-out end cover, an electrical appliance jack, a shell, a pump member, a brushless electrical motor and a controller, wherein, the pump member comprises a pump body, a pump wheel and a pump cover. The brushless electrical motor comprises a stator, a stator winding member, a rotor member and a hall sensor, wherein, the rotor member axle passes through the pump body and is connected with the pump wheel. The controller is designed into layered structure which has smaller size and can be arranged in the shell. The invention has the advantages that the trinitarian structure of the pump member, the brushless electrical motor and the controller is formed by arranging the controller inside the fuel pump; therefore, the structure has the advantages of compact structure, and the shape size of the invention is roughly equal to the electromotion fuel pump of the prior brush electrical motor. The new product and the old product are interchangeable and replaceable, thereby enlarging application field of the product. The brushless electrical motor fuel pump can be produced and used in batch.

Background technique
At present, electric fuel punp commonly used comprises motor, the pump parts, shell, fuel-displaced end cap, electrical outlet etc., its motor is generally brush motor, brushless electric machine is also arranged, with the comparatively approaching prior art of the present invention the patent No. being arranged is ZL02221711.8, name is called the patent of invention of " a kind of motorcar electric fuel pump that adopts brushless electric machine ", this patent disclosure following technological scheme: comprise end cap parts I, shell, stator and winding, pump housing parts, pump impeller, end cap parts II and Hall transducer, its inventive point is: Hall transducer places in the middle of stator and the winding, and the axle that the rotor part of rare-earth permanent magnet is installed passes pump housing parts and directly drives pump impeller.Its electronic switching circuit as control mechanism places the outside of electric fuel punp, the shortcoming of interchangeability difference when having the big and alternative brush motor fuel pump of volume, this patent is not further described and discloses the stator structure as one of key technology of small-sized brushless motor in addition, causes its practicability (manufacturability) relatively poor.
Summary of the invention
Technical problem to be solved by this invention overcomes the deficiencies in the prior art exactly, and a kind of compact structure, oil fuel pump of brushless motor with built-in controller that interchangeability is good are provided.
The technical solution adopted in the present invention is: oil fuel pump of brushless motor with built-in controller, comprise fuel-displaced end cap, electrical outlet, shell, pump parts, brushless electric machine and controller, the pump parts comprise the pump housing, pump impeller and pump cover, brushless electric machine comprises stator and coil assembly, rotor part, Hall transducer, the axle of rotor part passes the pump housing fixedlys connected with pump impeller, and controller is made as the hierarchy in less the placed shell of boundary dimension.
As further improvement, the stator of stator and coil assembly is formed by connecting by the stator component of a plurality of splits, and the winding on each stator component adopts the structural type of concentrating winding.
As further improvement, the joint between the stator component constitutes the groove of remaining silent, and the internal surface of stator component offers several grooves vertically.
Beneficial technical effects of the present invention is: owing to controller is located at the inside of fuel pump, the pump parts have been constituted, the Trinitarian structure of brushless electric machine and controller, advantage with compact structure, its boundary dimension is with also roughly the same at the electric fuel punp of the brush motor that uses at present, be convenient to old product general, substitute, enlarged the application of product, oil fuel pump of brushless motor can be produced in batches and use, the following advantage of oil fuel pump of brushless motor is really embodied: 1, do not had brush and commutator, improved the working life of product widely; 2, improved the operational efficiency of fuel pump widely, the use of saving power; 3, make fuel pump more can be used in the automobile of miscella power fuel; 4, cleaned fuel, reduced pollution, reduced and protected the wearing and tearing of motor fuel oil; 5, reduced the noise of fuel pump.
In addition, stator and coil assembly adopt the stator component packing of a plurality of splits, concentrate the structural type of winding, have really solved the technological problems of small size stator winding.
Moreover the joint between the stator component constitutes the groove of remaining silent, and the internal surface of stator component offers several grooves vertically, has improved magnetic conductive loop, has reduced location torque.
