DETAILED DESCRIPTION

[0026] The present invention is further described in detail below with reference to the accompanying drawings.

[0027] like Figures 1 to 10 As shown, in order to achieve the technical effect of "the transmission components can be quickly installed and removed on the output shaft of the motor", the structure and function of a motor are described in detail below;

[0028] A motor comprises a motor housing 11, wherein two support disks 12 are fixedly connected in the motor housing 11, two stators 13 are fixedly connected in the motor housing 11, a rotor shaft 21 is rotatably connected between the two support disks 12, a commutator 22 is fixedly connected to the rotor shaft 21, two brushes 31 are fixedly connected to the support disk 12, the brushes 31 are in contact with the commutator 22, a rotor core 23 is fixedly connected to the rotor shaft 21, a rotor winding is wound on the rotor core 23, the rotor winding is connected to the commutator 22, a mounting sleeve 24 is fixedly connected to the rotor shaft 21, and a stepped groove 25 is provided on the mounting sleeve 24;

[0029] There are two stepped grooves 25, and the stepped grooves 25 include a transverse slot and a plurality of vertical positioning grooves;

[0030] The rotor shaft 21 is fixedly connected to two heat dissipation impellers 41, and the two heat dissipation impellers 41 are respectively located on the outer sides of the support plate 12, and the support plate 12 is provided with a plurality of ventilation holes;

[0031] The rotor shaft 21 is provided with a transmission component 51 , and a clamping block 52 is fixedly connected to the inner side of the transmission component 51 , and the clamping block 52 can be inserted into the stepped groove 25 ;

[0032] When using, Figure 1 As shown, two brushes 31 are powered, the two brushes 31 pass current to the commutator 22, the commutator 22 passes current to the rotor winding wound on the rotor core 23, the rotor winding is excited, the two stators 13 are arc-shaped permanent magnets, and then the excited rotor winding is driven to rotate by the two stators 13, the rotor winding drives the rotor core 23 to rotate, and the rotor core 23 drives the rotor shaft 21 to rotate;

[0033] The rotor shaft 21 drives the two heat dissipation impellers 41 to rotate. When the two heat dissipation impellers 41 rotate, wind force is generated. The wind force passes through the inside of the motor housing 11, thereby dissipating the heat inside the motor housing 11.

[0034] Furthermore, when the power of the rotor shaft 21 needs to be output, the clamping block 52 on the transmission component 51 is inserted into the transverse slot provided on the stepped groove 25, and the transmission component 51 is rotated so that the clamping block 52 slides into the vertical positioning groove, thereby fixing the transmission component 51. Figure 4 and 5 As shown, the structure of the stepped groove 25 can be used to insert the clamping block 52 into the vertical positioning groove at different positions according to different usage requirements, so that the transmission component 51 is connected to different positions of the rotor shaft 21;

[0035] As in question 4 and Figure 5 As shown, the installation direction of the transmission component 51 is opposite to the rotation of the rotor shaft 21, that is, when the rotor shaft 21 rotates clockwise, the transmission component 51 rotates counterclockwise and snaps into the vertical positioning groove, so that the clamping block 52 contacts the side of the vertical positioning groove, and then when the rotor shaft 21 rotates clockwise, the transmission component 51 will not fall off from the vertical positioning groove, completing the transmission of torque. This installation method can quickly complete the installation of the transmission component 51 and the rotor shaft 21, and can also install the transmission component 51 at different positions on the rotor shaft 21 according to different usage requirements;

[0036] like Figures 8 to 10 As shown, since the shape and structure of the stepped groove 25 are special and it is a core structure in a motor, a motor processing device is designed to facilitate the processing of a motor. The structure and function of a motor processing device are described in detail below;
