# Torque control tool

## Abstract

A power tool and method of controlling a motor of the power tool based on a determination of torque is provided. The method of determining torque uses the energy output by the drive mechanism and the angle of rotation of the output shaft to estimate torque. The energy is determined by subtracting efficiency losses (or gains) from a nominal energy of the drive mechanism in order to improve the torque estimation.
