AI Technical Summary

Problems solved by technology

Both structures use damping rubber for vibration damping, but after the motor runs for a long time, the rubber is easily deformed, resulting in poor coaxiality between the outer rotor and the rotating shaft, resulting in increased electromagnetic excitation and reduced vibration damping effect

Embodiment Construction

[0022] see in conjunction Figure 1 to Figure 3 As shown, according to an embodiment of the present application, a rotor core assembly includes:

[0023] The rotor core body, the rotor core body includes coiled plates, and the coiled plates are wound around the axis of the rotor core body.

[0024] The rotor core adopts a coiled plate structure, which is wound along the axis of the rotor core. The radial stiffness of the wound rotor is reduced the most, which can improve the stability of the rotor operation.

[0025] In some embodiments, the rolled plate includes a substrate 2 and a vibration-damping layer 21 , and the substrate 2 and the vibration-damping layer 21 are stacked along the thickness direction of the rolled plate.

[0026] The coil adopts a composite structure of the base plate 2 and the damping layer 21 , especially the presence of the damping layer 21 enables the rotor to have vibration damping capabilities in the tangential and axial directions.

Abstract

The present application provides a rotor core assembly, a rotor assembly and a motor. The rotor core assembly includes a rotor core body, the rotor core body includes coiled plates, and the coiled plates are wound around the axis of the rotor core body. The rotor core adopts the coiled plate structure, and the stiffness in the radial direction is reduced the most, so that it has the ability to reduce vibration and ensure the stability of the rotor operation.

Description

technical field [0001] The application belongs to the technical field of motors, and in particular relates to a rotor core assembly, a rotor assembly and a motor. Background technique [0002] In the small permanent magnet motors of the prior art, the rotor structure is generally composed of a rotating shaft, a rotor core, permanent magnets or magnetic tiles. This structure is only suitable for environments with low noise and vibration requirements. In the case of higher and higher, the rotor with the above structure can no longer meet the requirements of use. Therefore, several vibration reduction technologies have been proposed in related technologies, such as the use of expensive outer ring bearings with vibration-damping rubber for the rotor; Vibration-absorbing rubber. [0003] For rotor vibration reduction technology, there are two main categories: 1. The core of the inner rotor and the outer rotor are separated, and the middle is filled with rubber; 2. The inner and...
