[0030] As Figures 1-5As shown, an internally wound motor includes a motor stator 1 and a motor rotor 3 with magnets 2. The motor stator 1 has a wire terminal 4 and a winding coil holder 6 for winding wires 5. One end of the wire 5 is connected to the wire terminal 4, and the other end is wound on the winding coil holder 6. A first insulating limiting piece 7 is provided on the outside of the winding coil holder 6 for the wire 5 to pass through. The first insulating limiting piece 7 has a limiting groove 8 for limiting the wire 5. A second insulating limiting piece 9 is provided at the bottom outside the first insulating limiting piece 7, connected to the first insulating limiting piece 7 and whose top can be pressed against the first insulating limiting piece 7. The second insulating limiting piece 9 has an insulating pressure block 10 that matches the limiting groove 8. Because the motor stator 1 has a wire terminal 4 and a winding coil holder 6 for winding wires 5... The coil holder 6 has a wire terminal 4 for external connection. When multiple turns of wire 5 are wound on the coil holder 6, the wire 5 can be tightly wound on the coil holder 6, making the wire 5 neater during wiring. This reduces the space required for winding and thus reduces the winding length, thereby reducing costs. Since the first insulating limit plate 7 has a limit groove 8, the wound wire 5 can be limited, making the winding of the wire 5 more orderly. The insulating pressure block 10 on the second insulating limit plate 9 can press against the first insulating limit plate 7, thereby limiting and protecting the wire 5 on the first insulating limit plate 7, preventing the wire 5 from being worn or broken during motor disassembly.

The winding connection block 11 is designed to facilitate the winding of the conductor 5 onto the winding connection block 11. The winding protection block 13 isolates and protects the wound conductor 5. The winding connection block 11, the winding limit block 12, and the guide insertion bar 14 are integrated into one unit. This integrated structure simplifies the overall structure of the winding coil holder 6. In this invention, there are eight winding connection blocks 11 and eight winding limit blocks 12. In practical applications, the number of winding connection blocks 11 and eight winding limit blocks 12 can be adjusted as needed.
