Abstract
An aspect of the present disclosure is drawn to a system for use with a torque tool and a fastening element. The torque tool has a motor and an engaging mechanism. The engaging mechanism can transfer a first torque to the fastening element when the motor operates in a first rotation mode and can transfer a second torque to the fastening element when the motor operates in a second rotation mode. The system includes a torque detector that detects a magnitude of torque applied to the fastening element and outputs a torque signal; and a controller that outputs a first drive signal to cause the motor to operate in the first rotation mode and outputs a second drive signal to cause the motor to operate in the second rotation mode based on the torque signal.

A reaction force mitigation (RFM) system for a torque tool having an engaging mechanism and a motor, the RFM system comprising:
- a torque detector operable to detect a magnitude of torque (TD) applied to a fastening element by the torque tool and output a torque signal based on the detected TD;
- and
- a controller having one or more processors and a non-transitory memory having instructions of computer-executable program code, which when executed by the one or more processors of the controller, causes the controller to perform operations that include outputting:
- a first drive signal to cause the motor to operate in a first rotation mode to cause the engaging mechanism to rotate at a first rate that transfers a first torque to the fastening element, and
- a second drive signal, based on the torque signal, to cause the motor to operate in a second rotation mode to cause the engaging mechanism to rotate at a second rate that transfers a second torque to the fastening element.
A torque tool, comprising:
- an engaging mechanism operable to engage a fastening element;
- and
- a motor that is operable in a plurality of operating modes that include a first rotation mode to rotate the engaging mechanism at a first rate to transfer a first torque to the fastening element, and a second rotation mode to rotate the engaging mechanism at a second rate to transfer a second torque to the fastening element;
- a torque detector operable to detect a magnitude of torque (TD) applied to the fastening element and to output a torque signal based on the detected TD;
- and
- a controller having one or more processors and a non-transitory memory having instructions of computer-executable program code, which when executed by the one or more processors of the controller, causes the controller to perform operations that include outputting:
- a first drive signal to cause the motor to operate in the first rotation mode, and
- a second drive signal to cause the motor to operate in the second rotation mode based on the torque signal.
A computer-implemented method of operating a torque tool having a motor and an engagement mechanism, the computer-implemented method comprising:
- controlling the motor to operate between a plurality of operating modes that include a first rotation mode and a second rotation mode that rotates the engaging mechanism;
- detecting a magnitude of torque (TD) applied to the fastening element;
- outputting a torque signal based on TD;
- outputting a first drive signal to cause the motor to operate in the first rotation mode that rotates the engaging mechanism at a first rate to transfer a first torque to the fastening element;
- and
- outputting, based on the torque signal, a second drive signal to cause the motor to operate in the second rotation mode that rotates the engaging mechanism at a second rate to transfer a second torque to the fastening element.
