Abstract
The utility model discloses a brushless motor fuel oil pump with a built-in controller, comprising an oil out end cap, an electric appliance jack, a housing, a pump component, a brushless motor and a controller. The pump component consists of a pump body, a pump impeller and a pump cover, and the brushless motor is composed of a stator and a winding component, a rotor part and a hall sensor. A shaft of the rotor part is fixedly connected with the pump impeller after drilling through the pump body. The controller is designed into a laminated structure with a relatively small external dimension, which can be positioned in the housing. The beneficial technical effect is that: for the controller is arranged in the fuel oil pump, the triune structure of the pump component, brushless motor and controller is formed, having the advantage of impact structure. The external dimension of the utility model is similar to the present electric fuel pump of a brush motor, so that the utility model is applicable to be used in general purpose by the prior products or replace the prior product. Therefore, the application range of the product is enlarged, and the batch production and usage of the brushless motor fuel oil pump are realized.
Description
Technical field
The utility model relates to and a kind of the pressure fuel oil is transferred to the electric fuel punp of the ejecting system of internal-combustion engine, relates in particular to a kind of oil fuel pump of brushless motor with built-in controller.
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 utility model the patent No. being arranged is ZL02221711.8, name is called the utility model patent 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 in the utility model 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 technological scheme that the utility model adopted 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.
The utility model beneficial technical effects 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.
