| Abstract: | Hysteresis gyro motor is one of the significant parts of gyro in an inertial sensor. Meanwhile, the lifespan of hysteresis gyro motor determines the lifespan of the inertial sensor. Focused on the main failure mode, lubrication system is improved to prolong the lifespan of hysteresis gyro motor. The lifespan test demonstrates that the MTTF（mean time to failure）is longer than thirty thousand hours. |
