The mandrel 20 1 of the base 200 passes through the first accommodating space 2 2 1 of the drive shaft 20 and directly projects into and is received in the second accommodating space 2 communicating with the first accommodating space 2 2 1 . 2 2, and the drive shaft 20 is further provided with a recessed area 2 3 at the outer edge of the large diameter portion 2 2 . The bearings 24 and 25 can be respectively sleeved in the recessed area 2 3 of the outer edge of the large diameter portion 22 The small diameter portion 2 1 of the drive shaft 20 and the large diameter portion 22 are connected to each other. [〇〇31] The drive shaft 20 of the motor 100 is supported by the first transmission member 41 disposed in the first accommodation space 21, the second transmission member 42 on the spindle 201 of the base 200, and the coupling The member 4 3 causes the drive shaft 20 and the mandrel 210 to achieve a direct radial coaxial assembly transmission to greatly reduce the space required for the two-axis joint, and by the large-diameter portion 2 2 the front and rear ends of the bearing 2 4 form No. 101 0101 Page 9 / Total 24 pages M408878 __ Two on June 3, 100, the shuttle is changing the page, the configuration of 2 5, so that the mandrel 2 0 1 is transmitted through the first transmission member 4 1 and the second transmission member 4 2 Rotate smoothly with the drive shaft 20 - and. [0032] Furthermore, a fan 50 is further disposed on the spindle 2 0 1 of the base 200, so that the fan 50 is disposed between the motor 100 and the base 200, and the fan 5 is installed. 0 is provided at the center of the blade thereof with a concave shaft 5 1 for accommodating and tightly fitting the second transmission member 4 2 which is also sleeved on the spindle 2 0 1 ^ [〇〇33] due to the body of the motor 1 0 0 The structural gap existing between the 10 and the base 200, so that the outer cover and the motor assembly structure are blocked by an end cover 60 interposed between the motor 1000 and the base 200. The gaps are partially communicated for dust protection purposes, and the end caps 60 also have the function of limiting the relative position of the fan 50. In this embodiment, a plurality of vent holes 6-1 are further formed in the end cover 60 to facilitate the heat dissipation effect of the fan 50 rotation to flow the airflow. [0034] Please refer to FIGS. 7 and 8 , which are schematic exploded and cross-sectional views showing the second embodiment of the present invention. In the second embodiment, the main components are the same as the first embodiment, so the same component symbols are used for the same. Cross-reference and omit the relevant description. [0035] In the second embodiment, the fan 5 OA is integrally formed with the second transmission member 42, so that the second transmission member 42 is integrally formed at the axis of the fan 50 A, and can be combined with the fan 5. Ο A can be fixed to the mandrel 2 0 1 together, and the fan 5 Ο A is provided by the vent hole 6 1 which is also located on the end cover 60 between the motor 100 and the frame 200 The airflow generated when the second transmission member 42 is rotated in the body can flow more smoothly to dissipate heat and reduce noise and failure rate. Form No. A0101 Page 10 of 24 M408878 June 09, 100 Nuclear Replacement Page [0036] In the assembly structure of the motor designed by the present invention, the first transmission member 41 and the spindle 201 on the drive shaft 20 are utilized. The structure of the upper transmission member 42 cooperates with the coupling member 43 interposed between the two transmission members, so that the motor 1000 can directly achieve the radial coaxial drive purpose with the spindle 2 0 1 of the base 200. As shown in Figures 5 and 6, there is no need to perform additional concentric corrections prior to assembly. Furthermore, since the motor 100 in the assembled structure, the mandrel 2 0 1 of the base 200, the first transmission member 4, the second transmission member 4, and the coupling member 43 together achieve radial coaxial drive When the power transmission of the assembly structure of the motor designed by the present invention is performed, the coupling member 43 interposed between the first transmission member 4 1 and the second transmission member 42 is at the large diameter portion 2 of the drive shaft 20 2 is subjected to the mechanical torsion of the transmission member, and the coupling member 43 can automatically eliminate the tolerance of the mandrel between the two shafts while being pressed, thereby greatly reducing the vibration phenomenon when transmitting power, especially avoiding the startup. The resulting momentary shocks to ensure the smoothness and accuracy of the overall power transmission. [0037] In addition, only the coupling member 4 that directly bears the transmission and is naturally worn during the subsequent maintenance and repair can save the maintenance cost of the maintenance, and the first transmission member 4 1 can be extended by the arrangement of the coupling member 43.
