Title: DRIVE UNIT FOR CIRCUIT BREAKERS, SWITCHGEAR, AND MOTOR CONTROL CENTERS
Abstract:
Disclosed herein is a drive unit for driving a tool mated with a tool receptacle in a device. The drive unit includes a tool carrying apparatus configured to carry the tool, and a proximity sensor cooperating with at least a portion of the tool carrying apparatus so as to detect movement of the tool carrying apparatus along a longitudinal axis thereof. A motor apparatus is configured to rotate the tool carrying apparatus. Control circuitry is configured to operate the motor in an engagement mode to rotate at least a portion of the tool carrying apparatus until the tool is rotationally aligned with the tool receptacle so as to permit insertion thereinto, based on the proximity sensor not detecting movement of the tool carrying apparatus a threshold distance along the longitudinal axis toward the tool receptacle.
