[0021] See also Figure 1 and Figure 2 The utility model provides a technical solution: including a rotor assembly 1, a front end cover 2, a stator assembly 3, a drive end bearing 4 and a non-drive end bearing 5, characterized in that: the non-drive end bearing 5 is embedded in the stator assembly 3, the hole of the non-drive end bearing 5 is matched with the non-drive end shaft of the rotor assembly 1, and the shaft of the non-drive end bearing 5 is matched with the inner hole on the stator assembly 3;

[0022] The drive end bearing 4 is embedded in the rotor assembly 1, the hole of the drive end bearing 4 is matched with the hollow shaft on the front end cover 2, and the shaft of the drive end bearing 4 is matched with the inner hole on the rotor assembly 1;

[0023] The rotary seal 6 is embedded in the front end cover 2. The outer diameter of the rotary seal 6 is smaller than the inner diameter of the drive end bearing 4 and can be close to or overlapped in the axial direction.

[0024] The motor structure of the device is compact, which ensures the performance of the motor and reduces the axial size, thereby reducing material costs and installation space, so that the equipment using the motor can also be reduced simultaneously.

[0025] like Figure 3 and Figure 4 As shown, the end of the rotor assembly 1 away from the non-drive end bearing 5 is connected to an elastic rotation component 7, and the outside of the elastic rotation component 7 is connected to a support component 8, and the outside of the support component 8 is connected to a connection component 9.

[0026] like Figure 4 As shown, the elastic rotating assembly 7 includes a rotating box 701, a coil spring 702 and a rotating shaft 703, and the coil spring 702 is installed inside the rotating box 701, and the rotating shaft 703 is installed inside the coil spring 702;

[0027] The rotating shaft 703 rotates elastically with the rotating box 701 through the coil spring 702, so that the mounting ring 901 can be buffered during the rotation process, thereby enabling the device to have a soft start function and avoiding damage to the device during startup.

[0028] like Figure 3 As shown, the support assembly 8 includes a first sliding ring 801, a support block 802 and a second sliding ring 803, and the outside of the first sliding ring 801 is connected to the support block 802, and the outside of the first sliding ring 801 is connected to the second sliding ring 803. The first sliding ring 801 is rotatably connected to the support block 802, and the support block 802 and the second sliding ring 803 are movably connected;

[0029] By connecting the first sliding ring 801 and the second sliding ring 803 with the support block 802 , the rotating box 701 can effectively support the mounting ring 901 without affecting the buffering function of the mounting ring 901 .

[0032] Working principle: The equipment is protected by a box composed of the front cover 2 and the stator assembly 3. Through the relationship between the rotor assembly 1 and the stator assembly 3, the rotor assembly 1 can rotate after the equipment is powered on. The non-drive end bearing 5 and the drive end bearing 4 both fix the rotor assembly 1 without affecting the active movement of the rotor assembly 1. The rotating seal 6 can seal the connection between the rotor assembly 1 and the front cover 2;

[0033] When the device is in use, the device to be driven is connected to the mounting ring 901. At this time, the device is energized so that the rotor assembly 1 rotates, which can drive the rotating box 701 to rotate. The rotating shaft 703 is buffered by the elastic structure between the coil spring 702 and the rotating box 701, so that the resistance of the device during rotation is reduced. The rotating shaft 703 rotates under the influence of the rotating box 701. During the rotation process, the rotating shaft 703 can drive the mounting ring 901 to rotate through the transmission rod 902, so that the mounting ring 901 drives the device required to be driven in this application.
