Embodiment Construction

[0040] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0041] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0042] In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be interpreted as indicating or implying relative importance or implicitly specify...

Abstract

The invention provides a rotating motor and a fan. According to the rotating motor provided by the invention, a plurality of accommodating grooves are formed in the radial inner surface of at least one bearing seat of a supporting frame at intervals, and soft arc-shaped petals are arranged in the accommodating grooves, so that the inner diameters of the soft arc-shaped petals are smaller than the inner diameters of the corresponding bearing seats, and the soft arc-shaped petals elastically abut against the corresponding bearings; therefore, a certain binding force is formed between each soft arc-shaped petal and the corresponding bearing, the axial and radial stress of the bearing can be improved, the service life of the bearing is prolonged, the relative position of the inner ring and the outer ring of the bearing can be adjusted during high-speed rotation, and a certain self-adaptive aligning effect is achieved; and the area between the two adjacent accommodating grooves in the bearing seat provided with the soft arc-shaped petals can be well connected with the corresponding bearing, so that the bearing can be more stably mounted in the corresponding bearing seat, and the operation stability and the reliability of the rotating motor are ensured.

Description

technical field [0001] The present application belongs to the field of electrical machines, and more specifically relates to a rotating electrical machine and a fan. Background technique [0002] As the speed requirements for rotating motors are getting higher and higher, for example, the operating speed is required to be from tens of thousands to hundreds of thousands of revolutions, or even hundreds of thousands of revolutions per minute. The coaxiality of the rotor and stator of the rotating electrical machine, the coaxiality of the bearing and the rotating shaft, the coaxiality between the two bearing seats corresponding to the bearings at both ends of the rotating shaft, and the coaxiality of the stator, rotor and bearing seats and other components High precision must be ensured to meet the high speed requirements of rotating electrical machines. At the same time, in order to improve the efficiency of the rotating electrical machine, the air gap between the stator and ...
