Abstract: 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.
