method and circuit for electronic production of a trembling in a mechanical lageranordnung

摘要

Electronic dither circuit for a mechanical bearing assembly having a housing with a member disposed in the housing. Means is provided in the form of a mechanical bearing assembly for pivotally mounting the member in the housing for movement about a pivot axis. Means is mounted in the housing forming a magnetic field in the housing. A torque coil is connected to the member and is disposed in the magnetic field. Electronic means is provided for supplying electrical energy to the torque coil. The electronic means includes a damped closed loop servo system and means for removing the damping from the closed loop servo to cause the servo loop to oscillate to thereby supply oscillatory electrical energy to said torque coil to cause the torque coil to oscillate and to thereby minimize the effects of friction.
