The brushless electric machine has the technical advantages that: because the stator and the winding part adopt subpackage of a plurality of split-type stator elements and the structural form of concentrated winding, the brushless electric machine solves the technology problem of small-sized stator winding, and has the advantage of simple manufacturing; therefore, the brushless electric machine ensures batch production and application of brushless electric machine fuel pump.
Description
Technical field
The utility model relates to a kind of brushless electric machine, relates in particular to a kind of brushless electric machine that is used for fuel pump.
Background technology
At present, the brushless electric machine that is used for fuel pump, comprise the stator and the coil assembly that are arranged in the shell, rotor part and Hall element, and controller that drives and control brushless electric machine, 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 technical scheme: comprise end cap parts I, shell, stator and winding, pump housing parts, pump impeller, end cap parts II and Hall element, its inventive point is: Hall element 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.This patent is not further described and discloses the stator structure as one of key technology of small-sized brushless motor, causes its practicality (manufacturability) relatively poor, exists to make shortcoming complicated and that not can manufacture.In addition, its electronic switching circuit as controlling organization (controller) places the outside of electric fuel punp, the shortcoming of interchangeability difference when having the big and alternative brush motor fuel pump of volume.
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 brushless electric machine that is used for fuel pump simple, that be suitable for producing in batches of making is provided.
The technical scheme that the utility model adopted is: the brushless electric machine that is used for fuel pump, comprise the stator and coil assembly, rotor part and the Hall element that are arranged in the shell, and controller that drives and control brushless electric machine, 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 version of concentrating winding.
The utility model beneficial technical effects is: because stator and coil assembly adopt the stator component packing of a plurality of splits, concentrate the version of winding, really solved the technological problems of small size stator winding, have the simple advantage of manufacturing, oil fuel pump of brushless motor can be produced in batches and use.
In addition, the junction between the stator component constitutes the groove of remaining silent, and the inner surface of stator component offers several grooves vertically, has improved magnetic conductive loop, has reduced location torque.
Moreover, controller is located in the shell, constituted the structure of one with fuel pump, advantage with compact conformation, its overall dimension is with at present also roughly the same at the electric fuel punp of the brush motor that uses, be convenient to general with old product, substitute, enlarged the application of product.
