A rotor assembly 6 is fitted onto the outer circular wall of the tapered shaft fixing seat 5 corresponding to the stator assembly 4.

By inserting the tapered shaft 7 into the tapered hole 52 in the middle of the tapered shaft fixing seat 5, and fixing the pressure cap 13 to the tapered shaft 7 and the tapered shaft fixing seat 5 respectively with bolts, the tapered shaft 7 is further locked in the middle of the tapered shaft fixing seat 5, improving the stability of the tapered shaft 7 after installation. Then, by installing and cooperating the front cover 2 and the rear cover 3, the tapered shaft 7 and the rotor assembly 6 are aligned with the stator assembly 4 inside the housing 1, facilitating the assembly of the motor or, in case of motor failure, facilitating disassembly and repair of the motor, thus improving the practicality of the equipment.

During installation, the front end cover 2 and the rear end cover 3 axially position the tapered shaft 7 and the tapered shaft fixing seat 5, improving the convenience of motor assembly or disassembly. This facilitates the quick installation of the rotor assembly 6 into the middle of the housing 1 or its removal from the middle of the housing 1.

[0025] Specifically, both the front cover 2 and the rear cover 3 have annular protrusions 8 on their sides that fit into the snap-fit ​​groove 101. Both the front cover 2 and the rear cover 3 have a boss 9 in the middle. The boss 9 has a mounting groove 10 in the middle. A bearing 11 is fitted inside the mounting groove 10. During installation, the front cover 2 and the rear cover 3 are connected by inserting the annular protrusions 8 into the snap-fit ​​grooves 101 at both ends of the housing 1, and then the front cover 2 and the rear cover 3 are conveniently fixed to both ends of the housing 1 by bolts.

[0026] Specifically, the stator assembly 4 includes several annularly spliced ​​stator teeth 41. Each stator tooth 41 has an insulating frame 42 at both ends. A coil winding (not shown in the figure) is wound around the outside of the insulating frame 42. Before the stator assembly 4 is installed in the middle of the housing 1, the coil winding is wound around the outside of the stator teeth 41 and the insulating frame 42 to facilitate the subsequent installation of the stator assembly 4 in the middle of the housing 1.

[0027] like Figure 4 As shown, specifically, the tapered shaft fixing seat 5 is tubular, the outer circular wall of the tapered shaft 7 is provided with a positioning groove 51, the tapered shaft fixing seat 5 is provided with a tapered hole 52 in the middle, the inner wall of the tapered hole 52 is symmetrically provided with a keyway 53, a connecting key 12 is installed in the keyway 53, a pressure cap 13 is provided on one side of the tapered hole 52, a connecting frame 14 is provided on one side of the tapered shaft fixing seat 5, and an encoder 15 is sleeved on the end of the connecting frame 14.
