ABSTRACT:
An angular micro-positioning system cable of readily accessing any angle within 360.degree. and thereafter precisely addressing an angular position within one ten-thousandth of a degree. The device is suitable for use in test equipment or any equipment requiring extremely precise angular positioning. The device includes a rotary motor which is mounted to a secondary frame which is pivotally mounted to a flexibly mounted main frame. The drive shaft of the rotary motor is biased in to engagement with the output wheel. A linear micro-positioner is mounted to the main frame and its drive shaft is coupled to the rotary motor frame to pivot same. The rotary motor is first rotated with the linear micro-positioner locked in place to provide coarse angle positioning. Thereafter, the drive shaft of the rotary motor is locked and the motor frame is pivoted by the linear micro-positioner which provides extremely fine angular adjustment.
