Embodiment

[0036] This embodiment provides a driving device including a motor and a coupling matched with an output shaft of the motor.

[0037] Specifically, refer to the motor figure 1 , which includes the base 100, the stator 220, the bearing seat 300, the outer rotor 210 and the output shaft.

[0038] The base 100 includes a bottom plate 110 and a fixing portion 120, see figure 2 and image 3 , wherein the bottom plate 110 is plate-shaped, including a first surface 111 and a second surface 112 opposite to each other, the fixing portion 120 is arranged on the second surface 112 of the bottom plate 110 and is located in the center of the bottom plate 110, and the fixing portion 120 is provided with a mounting hole 130, And the axis of the mounting hole 130 penetrates through the bottom plate 110 along the center line of the bottom plate 110 .

[0039] In this embodiment, the first surface 111 of the bottom plate 110 , that is, the surface of the bottom plate 110 without the mountin...

Abstract

The application relates to the technical field of the motor, and relates to a motor and a driving device. The motor comprises a base with an outward convex fixed part, a stator, a bearing seat, a bearing, an outer rotor and an output shaft, wherein the bearing seat is fixed at the end part of the fixed part, and the bearing is close to a load end of the output shaft. The motor provided by the invention adopts the bearing outer-ring type structure, the structure reliability of the motor I obvious enhanced, and the location of the bearing is close to the end cover of the bearing, namely, closerto the output end of the output shaft; compared with other motor in the prior art, the load distance connected with the output shaft is shortened, and the rigidity of the motor is obviously increased.Meanwhile, the driving device provided by the invention can provide larger load since the rigidity of the motor is stronger.

Description

technical field [0001] The present invention relates to the technical field of motors, and in particular, to a motor and a driving device. Background technique [0002] At present, most of the DD motors use the inner ring of the bearing to rotate. Even the outer rotor DD motor uses the inner ring to rotate, and due to the size, the small DD adopts a small bearing structure, which leads to the rigidity of the DD of this structure. It is not good enough, especially when it is applied to the occasion of unilateral bearing, due to the low rigidity, the accuracy is deteriorated, and even the encoder has no signal. SUMMARY OF THE INVENTION [0003] In a first aspect of the present invention, a motor is provided, which solves the defect that the existing motor bearing structure is unstable. [0004] In a second aspect of the present invention, there is provided a drive device powered by the above-mentioned motor. [0005] The present invention is realized in this way: [0006]...
