Abstract
An integrated gearbox/encoder and control system that includes: a gearbox with an output shaft connected to a mechanical load; a first sensor detecting the rotary position of the output shaft; a motor; a second sensor detecting the rotary position of the motor; and a system controller controlling motive drive to the motor. The two rotary position sensors permit direct determination of gearbox backlash which can be used in motor control. A drive current sensor similarly permits determination of a vibration signature for comparison with a standard.
