[0000] To achieve the above objective, in accordance with one embodiment of the invention, there is provided a sealing structure of a Hall element, comprising: a box body, a circuit board, and a Hall element disposed on the circuit board. The box body is provided with a chamber comprising a bottom wall. The bottom wall of the chamber is provided with a supporting boss, and the circuit board is supported by an upper surface of the supporting boss. The bottom wall of the chamber is depressed to form a mounting slot. The Hall element of the circuit board is inserted into the mounting slot. Sealing glue is injected into the chamber to seal the Hall element in the mounting slot and coat the circuit board.
[0000] In a class of this embodiment, a plurality of columns protrudes upward from the bottom wall of the chamber. The columns are sheathed in vias on the circuit board.
[0000] In a class of this embodiment, an outer wall of the box body is provided with a plurality of mounting feet. The mounting feet are provided with mounting holes.
[0000] A motor comprises a rotary shaft, a rotor assembly, a stator assembly, a shell assembly, a box body, a circuit board, and a Hall element. The rotor assembly is disposed on the rotary shaft. The stator assembly and the shell assembly are integrated and sleeved on the rotor assembly. The stator assembly comprises a stator core, a terminal insulator, and coil windings. The terminal insulator is disposed on one end of the stator core. The coil windings are coiled on the terminal insulator. The box body is disposed on the terminal insulator, and the box body is provided with a chamber comprising a bottom wall. The bottom wall of the chamber is provided with a supporting boss, and the circuit board is supported by an upper surface of the supporting boss. The bottom wall of the chamber is depressed to form a mounting slot. The Hall element of the circuit board is inserted into the mounting slot. Sealing glue is injected into the chamber to seal the Hall element in the mounting slot and coat the circuit board.
