Systematical drift of dynamically tuned gyro are defined with multiple factors, the most
predictable of which is rotor magnetization vector orientation in reference to synchro-
nous hysteresis drive rotor. The article presents experimental data on different dynami-
cally tuned gyros’ drive rotor magnetization vector rotation methods based on variation
of power supply parameters, such as voltage pulsing of various width or amplitude to
inductors of drive rotor. We also offer methods of actual drive rotor magnetism orienta-
tion vector and experimental data on systematical drift of dynamically tuned gyro quanti-
ty value. As a result the dependence of dynamically tuned gyro drift systematical compo-
nent of magnetization vector rotation was found. We formulated physical model of re-
searched dependence. This study could be valuable for engineers and students of
appropriate specialty.
Keywords: dynamically tuned gyro, drift, synchronous drive
