In order to solve the above technical problems, technical solution provided by the utility model are as follows: a kind of stator of DC brushless motor
Structure, including the stator core that several both ends are connected, the stator core is T-type structure, the T-type of two neighboring stator core
It is terminated between the both ends of structure for dovetail chase mortise, the top surface of the T-type structure is arcwall face, several stator cores are connected to form
The stator module of ring structure, the outer cover of the stator module are equipped with cylindrical casing, on the periphery of the stator module
Several semicircular screw holes for fixed stator component are uniformly distributed, the bottom end of the stator core is equipped with armature tooth.
As an improvement, the stator core is equipped with 12 altogether, wherein being equipped with spiral shell at the top of the T-type structure of three stator cores
Nail hole is equipped at interval of three stator cores in the stator module of the ring structure in the stator core that both ends are connected
One screw hole.
As an improvement, the both ends of the T-type structure of the stator core are respectively equipped with the dovetail groove to match, dovetail.
The utility model compared with prior art the advantages of be:
1) 12 stator cores carry out splicing positioning using swallow tail shaped slot tenon structure, make its radially and circumferentially without
Method is mobile, has the double effects of positioning with locking；
2) increase semicircular nail hole in the periphery for the stator module being spliced into, making stator armature, there are three equal in 120 °
The screw hole of even distribution is fixed with front and rear cover through armature for screw, is substituted with simple thin-walled circular casing different
Type casing simplifies motor housing design, saves material.
