Abstract

The invention relates to the technical field of motors, and provides a high-impact-resistant motor and an installation method thereof. According to the high-impact-resistant motor provided by the embodiment of the invention, the front end of a rotor is supported by a front end cover, the rear end of the rotor is supported by a rear end cover, the front end cover and the rotor are rotationally connected through a front bearing, the rear end cover and the rotor are rotationally connected through a rear bearing, and the rotor is buffered through an elastic pad; when the rotor is subjected to axial high-impact vibration, the elastic pad can absorb the vibration of the rotor, so that the vibration of the rotor is weakened, and the rotor can bear axial high impact; according to the motor, a shaft, a soft magnetic sleeve, a magnetic steel and a stainless steel sleeve are sleeved and packaged from inside to outside, so that the rotor is packaged into an integrated structure, the integrated strength of the rotor is improved by multiple times, and the rotor meets the impact requirement of an ultrahigh g value in the axial direction and also meets the requirement of resisting high impact vibration in the radial direction.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a high-impact-resistant motor and an installation method thereof. Background technique [0002] At present, in China, in terms of miniature special motors, especially in the field of coreless motors (motor diameter less than 32mm), imported motors are mostly used, but in the field of miniature motors with high impact acceleration of tens of thousands of g value for missile-mounted steering gear, Imported motors are restricted and cannot meet high impact requirements. Contents of the invention [0003] Embodiments of the present invention provide a high-impact-resistant motor and an installation method thereof, which can make the motor resist high-impact. The specific technical scheme is as follows: [0004] The first aspect of the embodiments of the present invention provides a high-impact motor, including a front end cover, a rear end cover and a rotor, a front bearing is ins...
