The technical scheme is as follows: the stator structure of the motor comprises an iron core, a coil, a frame, a terminal shell and a terminal, wherein the iron core and the frame are integrally molded, the frame is provided with a side wall, a bottom plate, a positioning wall and a front baffle wall, the positioning wall is provided with a positioning surface towards the front baffle wall, the terminal shell is provided with a hole, a cavity, a terminal groove, a notch, a positioning groove, a lock catch and a lock catch surface, the terminal shell is inserted into the frame which is molded on the iron core, the positioning wall is embedded into the positioning groove, and the positioning surface is in contact with the lock catch surface.

Further, the terminal is U-shaped, and comprises a power input column, a connecting body and a welding column, wherein the power input column penetrates through the hole and then is placed in the cavity, the connecting body is placed in the terminal groove and is fixedly connected with the bottom plate, and the welding column is placed in the opening and is fixedly connected with the front baffle wall.

Further, the number of the terminals is three, and the terminals on two sides and the terminal in the middle are respectively and symmetrically distributed in an alpha angle.

Further, the coils are three phases, and each phase is welded with the welding post of the terminal, respectively.

The beneficial effects are that: according to the stator structure of the motor, the terminal shell is inserted into the frame which is injection-molded on the iron core, the positioning wall is embedded into the positioning groove, and the positioning surface is in contact with the locking surface, so that the freedom degree of movement of the terminal shell is eliminated, the terminal shell, the iron core and the frame are fixedly connected into a whole, and the split type connection structure of the terminal shell and the iron core is convenient for automatic production of an injection molding machine, and greatly improves the production efficiency of the motor stator.
