[0034] Detailed explanation of usage: The permanent magnet AC servo driver is a controller used to control the servo motor. When in use, the body 1 is connected to the servo motor with the help of the connecting cable and the interface 6, and then the control panel 2 is operated to control the servo motor. When it is necessary to install the heat sink 32 to improve the heat dissipation effect of the body 1, first move the handle 33 to drive the fixing plate 31 so that the limiting hole 38 on the fixing plate 31 is aligned with the rubber plug 39. First, insert the rubber plug 39 into the limiting hole 38 on one side of the fixing plate 31 to temporarily fix and support the fixing plate 31, so that the next fixing step can be facilitated. In this process, it is necessary to remove the adjusting ring 36 on the boss 35 at the same time, and then insert the boss 35 on the body 1 into the slot 34, and then put the adjusting ring 36 on the arc surface of the boss 35, and finally rotate the adjusting ring 36 to move along the arc surface of the boss 35, so that the adjusting ring 36 drives the rubber pad 37 and The fixing plate 31 is in contact with the heat sink 32 to complete the installation of the heat sink 32. When the heat sink 32 needs to be removed, the adjusting ring 36 is first rotated to separate the boss 35, and then the handle 33 is moved to drive the fixing plate 31 to separate the limiting hole 38 on the fixing plate 31 from the rubber plug 39, and the removal of the heat sink 32 is completed. Among them, by setting the heat sink 32 to be wavy, the area of ​​the connection between the heat sink 32 and the body 1 can be effectively increased, thereby improving the heat dissipation effect of the heat sink 32.

After the heat sink 32 is worn out during use, it can be easily replaced by personnel.

[0035] When the permanent magnet AC servo drive is not in use and needs to protect the interface 6 and the control panel 2, first rotate the protective cover 43 to move in the direction close to the body 1, and the connecting cover drives the mounting plate 44. When the mounting plate 44 is aligned with the screw 46, the protective cover 43 will just cover the interface 6, and then rotate the screw 46 to connect with the mounting plate 44 to complete the protection of the interface 6 and the control panel 2. When the cover servo drive needs to be used, first rotate the screw 46 to separate the mounting plate 44. At this time, the coil spring 47 can drive the protective cover 43 to rotate quickly in the direction away from the control panel 2, achieving The protective cover 43 can be opened quickly, wherein, after the protective cover 43 covers the interface 6 and the control panel 2 on the body 1, the sealing ring 48 can block the gap between the protective cover 43 and the body 1, thereby further improving the sealing performance of the protective cover 43. By setting the auxiliary structure 4, when the permanent magnet AC servo drive is in the process of transportation or when it is not in use, the protective cover 43 can be easily adjusted to seal and protect the interface 6 and the control panel 2 on the body 1, thereby avoiding damage caused by collision between the interface 6 and the control panel 2, thereby improving the practicality of the servo drive.
