DETAILED DESCRIPTION

[0025] The technical solution provided by the present invention will be further described below with reference to the accompanying drawings and according to specific implementation methods.

[0026] like Figures 1 to 8As shown, it includes a motor housing 1, which includes a base housing 101. The sticker is that adjustment slots 102 are fixedly installed on both sides of the base housing 101, and a permanent magnet support plate 108 is installed in the adjustment slot 102 for horizontal sliding. A permanent magnet bracket 109 is fixedly installed at the front end of the permanent magnet support plate 108, and a permanent magnet is fixedly installed on the inner wall of the permanent magnet bracket 109. A motor output shaft 2 is installed in the center of the base housing 101 for horizontal sliding. The motor output shaft 2 includes an outer output shaft 201, which is installed in the center of the base housing 101 for horizontal sliding. The middle section of the outer output shaft 201 is installed with a coil assembly for horizontal rotation along the axis. Ring 202, two pairs of coil support plates 203 are fixedly installed on the outer ring of the coil assembly ring 202, and the coil support plates 203 are evenly arranged on the surface of the coil assembly ring 202. The staggered angle between the two pairs of coil support plates 203 is 90 degrees. A plurality of winding cores 204 are fixedly installed on the coil support plates 203, and coil windings are wound on the winding cores 204. A plurality of heat dissipation baffles 205 are fixedly installed on the coil assembly ring 202, and the heat dissipation baffles 205 are fixedly installed between the two coil support plates 203 to separate adjacent winding cores 204. When the motor is working, the heat dissipation baffles 205 are used to isolate the heat generated by the coil.

[0027] like Figures 1 to 8 As shown, replacement ports are provided on both sides of the top of the housing top cover 104 for quickly detecting the status of the permanent magnet in the permanent magnet bracket 109 and facilitating its replacement. A pair of inspection covers 105 are installed in the replacement ports on the top of the housing top cover 104 for horizontal sliding.

[0028] like Figures 1 to 8As shown, the front end of the outer output shaft 201 is a hollow rod, and the front end of the coil assembly ring 202 is fixedly installed with a coil conversion rod 209, which is rotatably installed in the hollow rod at the front end of the outer output shaft 201. A pair of traction permanent magnets 210 are fixedly installed on the inner wall of the coil conversion rod 209, and an adjustment ring 106 is installed at the front end of the base shell 101 for transverse rotation. The adjustment ring 106 rotates coaxially with the outer output shaft 201, and a pair of adjustment magnets 107 are fixedly installed on the adjustment ring 106. The adjustment magnets 107 are opposite to the traction permanent magnets 210. A pair of coil top plates 206 are fixedly installed in the outer output shaft 201, and the coil top plates 206 are fixedly installed at both ends of the coil assembly ring 202. A pair of energized sliders 208 are fixedly installed on the inner side of the coil top plate 206, and the energized sliders 208 are located on the left and right sides of the coil top plate 206. The coil top plate 206 is connected to the external control system through a wire, and the two ends of the coil support plate 203 are fixedly installed. It is equipped with an energized slide 207, which contacts and cooperates with the energized slider 208 to start the coil winding on the winding core 204. When the coil on the coil support plate 203 becomes hot due to long-term operation, the adjusting ring 106 is rotated to pull the traction permanent magnet 210 through the adjusting magnet 107 on the adjusting ring 106, driving the coil conversion rod 209 and linking the coil assembly ring 202 to rotate within the outer output shaft 201, adjusting the rotation angle of the coil assembly ring 202 within the outer output shaft 201, rotating the coil support plate 203 in a horizontal position to a vertical position on the coil assembly ring 202 for cooling, and rotating the coil support plate 203 originally in a vertical position on the coil assembly ring 202 to a horizontal position, and driving it through the cooled winding core 204, thereby preventing the overheated winding core 204 from generating heat radiation to the permanent magnet on the coil conversion rod 209, reducing the magnetic field degradation rate, and increasing the service life of the permanent magnet.

[0029] like Figures 1 to 8 As shown, an oblique sliding groove is provided on the outer side of the permanent magnet support plate 108, and a pair of adjusting dial plates 103 are installed in the horizontal sliding in the adjusting groove 102. An adjusting push rod is fixedly installed at the front end of the adjusting dial plate 103, and a cylindrical key is fixedly installed on the adjusting push rod. The cylindrical key on the adjusting push rod at the front end of the adjusting dial plate 103 slides with the oblique sliding groove on the outer side of the permanent magnet support plate 108. By toggling the adjusting dial plate 103 to slide in the adjusting groove 102, the adjusting push rod on the adjusting dial plate 103 is driven to push the permanent magnet support plate 108 to slide toward the inside of the base shell 101, and the distance between the permanent magnet on the permanent magnet bracket 109 and the winding core 204 can be adjusted, so as to adjust the magnetic field influence of the permanent magnet on the permanent magnet bracket 109 on the winding core 204, thereby adjusting the load of the external output shaft 201, so that it can be used in applications where frequent load changes are required.

[0030] like Figures 1 to 8As shown, a shell top cover 104 is fixedly installed on the top of the base shell 101, and a cooling support plate 111 is longitudinally slidably installed on the bottom of the base shell 101 and the top of the shell top cover 104. A tension spring is fixedly installed between the cooling support plate 111 and the base shell 101 and the shell top cover 104. A plurality of low-temperature radiation plates 112 are fixedly installed on the inner wall of the cooling support plate 111. The low-temperature radiation plates 112 are used to radiate and cool the overheated winding core 204. A plurality of pressure switches 113 are longitudinally slidably installed on both sides of the inner wall of the cooling support plate 111. The pressure switches 113 correspond to the low-temperature radiation plates 112. A pair of contact pins 211 are fixedly installed on the upper and lower ends of the coil top plate 206. The contact push rod 211 contacts and cooperates with the pressure switch 113, and a pair of adjusting oblique rods 114 are fixedly installed at the front and rear ends of the cooling support plate 111. A pair of adjusting triangular keys 110 are fixedly installed at the front and rear ends of the permanent magnet bracket 109. The adjusting triangular keys 110 slide and cooperate with the adjusting oblique rods 114. When the permanent magnet support plate 108 is driven to slide inward by toggling the adjusting dial 103, the adjusting oblique rods 114 are driven to slide inward of the base shell 101 by the adjusting triangular keys 110 at the front and rear ends of the permanent magnet bracket 109, so that the low-temperature radiation plate 112 is close to the heated winding core 204. At the same time, the contact push rod 211 contacts and presses the pressure switch 113 to turn on the low-temperature radiation plate 112, thereby cooling the winding core 204.

[0031] like Figures 1 to 8 As shown, an annular permanent magnet is fixedly installed on the outside of the coil top plate 206, and anti-collision top plates 115 are fixedly installed on both ends of the inner side of the base shell 101. An annular permanent magnet is fixedly installed on the inner side of the anti-collision top plate 115. The annular permanent magnet on the inner side of the anti-collision top plate 115 repels the annular permanent magnet on the outer side of the coil top plate 206. When the outer output shaft 201 slides to both sides of the base shell 101, the outer output shaft 201 is decelerated and changed in direction by the repulsion of the magnetic rings, thereby improving the stability of the outer output shaft 201 during operation.
