It generates torque in a magnetic field through electric current, driving the rotor to rotate and achieve power transmission. Based on their operating principles, motors can be categorized as DC motors and AC motors. They are widely used in industrial production, transportation, household appliances, and other fields. Each type of motor has its own characteristics and application scenarios. For example, DC motors are simple and easy to control, making them suitable for precision applications; while AC motors have high power and efficiency and are commonly used in high-power equipment. The development of motors has driven the advancement of modern technology and has become an indispensable component of modern society.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example: Figure 1-5 As shown, the utility model provides a motor that can be quickly stopped, including a motor body 1 and a rotating shaft 3. A connecting seat 2 is fixedly connected to one side of the motor body 1, and the connecting seat 2 is movably sleeved on the outside of the rotating shaft 3. A stop disc 4 is provided on the side of the connecting seat 2 away from the motor body 1, and one end of the rotating shaft 3 movably passes through the stop disc 4. A mounting groove 5 is provided on the side of the motor body 1 close to the stop disc 4, and a driving component is provided inside the mounting groove 5. A slide groove 7 is provided on the side of the motor body 1 close to the mounting groove 5, and a slider 8 is slidably engaged with the inside of the slide groove 7. The slider 8 is fixedly connected to a telescopic rod 9 on the side close to the motor body 1, and the end of the telescopic rod 9 away from the slider 8 is fixedly connected to a fixed plate 10. The side of the fixed plate 10 away from the telescopic rod 9 is fixedly connected to a friction block 11, and the friction block 11 is in contact with the stop disc 4.

[0021] The driving assembly includes a coil 6 , which is fixedly mounted in the mounting groove 5 and electrically connected to the motor body 1 . A magnet 12 is fixedly connected to a side of the fixing plate 10 away from the friction block 11 .

[0022] By adopting the above technical solution, when the motor body 1 is energized, the current generates a magnetic field when passing through the coil 6, which attracts the magnet 12, so that the friction block 11 is separated from the anti-rotation disk 4, thereby facilitating the rotation of the shaft 3.

[0023] A key 14 is fixedly connected to the side of the rotating shaft 3 close to the connecting seat 2, and a spline 15 is movably sleeved on the outer side of the rotating shaft 3. A key slot 16 is provided on the spline 15, and the key slot 16 is slidably engaged with the outer side of the key 14. A flower groove 17 is provided on the inner side of the anti-rotation disk 4, and the flower groove 17 is movably sleeved on the outer side of the key slot 16.

[0024] By adopting the above technical solution, through the cooperation between the key 14 and the spline 15, when the shaft 3 rotates, the spline 15 is driven to rotate, and the cooperation between the spline 15 and the groove 17 is utilized to simultaneously drive the anti-rotation disk 4 to rotate.

[0025] The side of the connecting seat 2 away from the motor body 1 is fixedly connected with a centrally symmetrically distributed screw 18, and the side of the anti-rotation disk 4 away from the connecting seat 2 is provided with a limit plate 19. The end of the screw 18 away from the connecting seat 2 is movable through the limit plate 19 and is threadedly connected with a nut 20.

[0026] By adopting the above technical solution, the end of the screw 18 away from the connecting seat 2 is moved through the limit plate 19, and the position of the limit plate 19 is fixed by tightening the nut 20, and the stop plate 4 is limited by the limit plate 19.

[0027] A spring 13 is provided between the side of the slider 8 away from the fixing plate 10 and the inner wall of the sliding groove 7 .

[0028] By adopting the above technical solution, by setting the spring 13, it is convenient to reset the friction block 11. At the same time, the elastic force of the spring 13 is utilized to make the friction block 11 conflict with the anti-rotation disk 4, thereby inhibiting the rotation of the anti-rotation disk 4, and then inhibiting the rotation of the rotating shaft 3.

[0029] A protective cover 21 is fixedly mounted on one side of the motor body 1 and outside the anti-rotation disk 4 . The side surface of the protective cover 21 is provided with heat dissipation holes 22 that are centrally and symmetrically distributed.

[0030] By adopting the above technical solution, by providing the protective cover 21, the anti-rotation disk 4 is easily protected, and by providing the heat dissipation holes 22, the heat inside the protective cover 21 is easily exchanged with the external heat.

[0031] A bearing 23 is provided inside the protective cover 21 , and the bearing 23 is movably sleeved on the outer side of the rotating shaft 3 .

[0032] By adopting the above technical solution and providing the bearing 23 , the rotating shaft 3 can be rotated better.

[0033] The anti-rotation disk 4 is provided with a plurality of heat dissipation slots 24 .

[0034] By adopting the above technical solution, heat is generated when the friction block 11 rubs against the heat dissipation groove 24 . By providing the heat dissipation groove 24 , the heat on the surface of the anti-rotation plate 4 can be better dissipated.

[0035] Working principle: When the motor is in use, when the motor body 1 is energized, the current generates a magnetic field when passing through the coil 6, which attracts the magnet 12, causing the friction block 11 to separate from the anti-rotation disk 4, while pushing the slider 8 and the telescopic rod 9 to move toward the side of the spring 13 and compressing the spring 13, thereby facilitating the rotation of the shaft 3. When the shaft 3 rotates, it drives the spline 15 to rotate, and the cooperation between the spline 15 and the flower groove 17 drives the anti-rotation disk 4 to rotate at the same time;

[0036] When the motor stops, the magnetic field generated by the coil 6 also disappears. At this time, the elastic force of the spring 13 is used to push the slider 8, the telescopic rod 9, the fixed plate 10 and the friction block 11 to move to one side of the anti-rotation disk 4, so that the friction block 11 contacts the surface of the anti-rotation disk 4 and suppresses the rotation of the anti-rotation disk 4, thereby causing the anti-rotation disk 4 to stop quickly.

[0037] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
