ABSTRACT:
A system and method for precision fastening of a fastener. The fastening system includes a motor and a sensor that provides a feedback signal from the motor to a controller. The controller compares the feedback signal to a threshold value to determine if an error condition exists. If the error condition exists, the controller oscillates a rotor to the motor between a first and a second position. In one construction, a resolver provides a signal to the controller representing a position of the oscillating rotor. The oscillating rotor vibrates the housing, thereby alerting an operator of the error condition. In one construction, the fastener device can alert the operator that the fastener is not tightened to a proper torque, and that the fastener is not rotated through a proper angle of rotation.
