Description
Technical field
The utility model belongs to machine-building, particularly a kind of automobile electric booster steering system brushless DC motor stator structure.
Background technology
At present, the motorcar electric of domestic production helps the iron core to system brushless DC motor stator structure to be mostly integral type around structure, this class formation shortcoming is a lot, not only coiling difficulty, and poor insulativity, due to can not injection moulding insulating barrier, iron core surface can only be wrapped in insulating paper, it is very easily damaged in winding process, thus causes short circuit.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provides that a kind of cost is low, good insulation preformance, coiling automobile electric booster steering system brushless DC motor stator structure easily.
The technical scheme that the utility model technical solution problem adopts is: automobile electric booster steering system brushless DC motor stator structure comprises stator casing, armature winding, before being characterized in stator lamination, triangular in shapely respectively on trailing flank be laid with three riveting points, stator lamination left side is provided with the recessed snap close of stator lamination end face, stator lamination right side is provided with the convex snap close of stator core end face, stator core is formed by riveting point riveted by multiple stator lamination, before stator core, front end insulator and rear end insulator trailing flank be equipped with respectively, the outside of front end insulator and rear end insulator is wound around armature winding, multiple stator core Contiuum type annular array, and by between the recessed snap close of stator lamination end face and the convex snap close of stator lamination end face lock and spacing, the sealed rear interference fit of multiple stator core Contiuum type annular array is fitted in stator casing.
The beneficial effects of the utility model are: automobile electric booster steering system brushless DC motor stator infrastructure cost is low, good insulation preformance, both while can avoiding short circuit, coiling is also very convenient, especially the appropriate design of stator core, substantially increase the safety and reliability of product, meet the requirement of automobile electric booster steering system brshless DC motor overall performance.
