[0026] As Figures 1 to 8As shown in the figure, it includes a motor housing 1. The motor housing 1 includes a base housing 101. The sticker lies in that adjustment slots 102 are fixedly installed on both sides of the base housing 101. A permanent magnet support plate 108 is horizontally slidably installed in the adjustment slots 102. A permanent magnet bracket 109 is fixedly installed at the front end of the permanent magnet support plate 108. Permanent magnets are fixedly installed on the inner wall of the permanent magnet bracket 109. A motor output shaft 2 is horizontally slidably installed at the center of the base housing 101. The motor output shaft 2 includes an outer output shaft 201. The outer output shaft 201 is horizontally slidably installed at the center of the base housing 101. A coil assembly ring 202 is horizontally rotatably installed along the axis in the middle section of the outer output shaft 201. Two pairs of coil support plates 203 are fixedly installed on the outer ring of the coil assembly ring 202. 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 iron cores 204 are fixedly installed on the coil support plates 203. Coil windings are wound on the winding iron cores 204. A plurality of heat dissipation partitions 205 are fixedly installed on the coil assembly ring 202. The heat dissipation partitions 205 are fixedly installed between two coil support plates 203 to separate adjacent winding iron cores 204, and are used to isolate the heat generated by the coils through the heat dissipation partitions 205 when the motor is working.

[0027] As Figures 1 to 8 shown, replacement openings are provided on both sides of the top of the housing top cover 104 for quickly detecting the state of the permanent magnets in the permanent magnet bracket 109 and facilitating their replacement. A pair of inspection covers 105 are horizontally slidably installed in the replacement openings at the top of the housing top cover 104.

[0028] As Figures 1 to 8As shown, the front end of the outer output shaft 201 is a hollow rod, and a coil conversion rod 209 is fixedly installed at the front end of the coil assembly ring 202. The coil conversion rod 209 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. An adjustment ring 106 is rotatably installed at the front end of the base shell 101. The adjustment ring 106 rotates coaxially with the outer output shaft 201. 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. The coil top plates 206 are fixedly installed at both ends of the coil assembly ring 202. A pair of power-on sliders 208 are fixedly installed on the inner side of the coil top plates 206.

The two ends of the coil support plate 203 are respectively fixedly installed The coil support plate 203 is provided with an energized slide groove 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 is heated 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, thereby driving the coil conversion rod 209 and linking the coil assembly ring 202 to rotate in the outer output shaft 201, adjusting the rotation angle of the coil assembly ring 202 in 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 through the cooled winding core 204, so as to avoid the overheated winding core 204 from generating heat radiation to the permanent magnet on the coil conversion rod 209, reduce the magnetic field degradation rate, and increase 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 adjusting groove 102 for horizontal sliding. 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, so as to adjust the distance between the permanent magnet on the permanent magnet bracket 109 and the winding core 204, 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 in the figure, a housing top cover 104 is fixedly installed on the top of the base housing 101. A cooling support plate 111 is longitudinally slidably installed between the bottom of the base housing 101 and the top of the housing top cover 104. Tensile springs are fixedly installed between the cooling support plate 111 and the base housing 101 and the housing 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 for radiating and cooling 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 adjusting triangular keys 110 are fixedly installed at the front and rear ends of the permanent magnet support 109. The adjusting triangular keys 110 are in sliding cooperation with the adjusting inclined rods 114. When the adjusting dial 103 is toggled to drive the permanent magnet support plate 108 to slide inward, the adjusting inclined rods 114 are driven to slide inward of the base housing 101 through the adjusting triangular keys 110 at the front and rear ends of the permanent magnet support 109, so that the low-temperature radiation plates 112 are close to the heating winding core 204. At the same time, the pressure switches 113 are pressed to be turned on by the contact between the contact top rods 211 and the pressure switches 113 to cool the winding core 204 by the low-temperature radiation plates 112.

[0031] As Figures 1 to 8 shown, a ring-shaped permanent magnet is fixedly installed on the outside of the coil top plate 206. Anti-collision top plates 115 are fixedly installed at both ends inside the base housing 101. Ring-shaped permanent magnets are fixedly installed on the inside of the anti-collision top plates 115. The ring-shaped permanent magnets on the inside of the anti-collision top plates 115 are repelled by the ring-shaped permanent magnets on the outside of the coil top plate 206, which is used to decelerate and change the direction of the external output shaft 201 when the external output shaft 201 slides to both sides of the base housing 101, so as to improve the stability of the external output shaft 201 during operation.
