Dynamical characteristics of the gyroscope during spin-up and erection procedure, and the influence of the straymagneticfield on gyro's drift and speed attenuation are investigated.
讨论了陀螺在驱动、定向过程中的动力学特性，以及杂散磁场对陀螺漂移和转速衰减的影响。
2
The magneticfield is without any stray fields, preventing magnetization of the tool.
所有的区域都有磁场，防止磁化工具。
3
Through analyzing the air-gap magneticfield, stray loss on the surface of rotor can be worked out and moreover temperature field distribution in rotor can be obtained.
