摘要：

A gyroscope motor is a precision component widely used in aerospace, aviation and other fields. Its accuracy is very sensitive to vibration. Vibration can also cause changes in the air-gap magnetic field in addition to changes due to the electromagnetic force. This paper presents a numerical simulation method for analyzing the electromagnetic characteristics of the gyroscope motor air gap subject to the coupled electromagnetic force and mechanical vibration. It analyzes the magnetic field in the gap in the axial and circumferential directions using a finite element method model, and then analyzes the magnetic characteristics of the gyroscope motor air gap subject to the coupled electromagnetic force and vibration. The method can be used to estimate the electromagnetic vibration to optimize the design of a gyroscope motor and extend its life.
