Traditional hand-tools are powered by human’s hands; however, the torque that is produced by human hands is limited and cannot be kept at a constant. To solve this problem, electric hand-tools have become more and more popular, as they provide the required amounts of constant output torque. Electric hand-tools can be driven by DC motor drive systems or brushless DC motor drive systems, which do not require commutators and brushes, and can provide high efficiency, low inertia, small volume, and low noise. Brushless DC motor drives are gradually replacing DC motor drives and have become a new trend.
Tianhua Liu and Chengwei Peng proposed a design and implementation of torque control and torque estimation for an electric hand-tool, enabling a hand-tool free of torque transducer and Hall-effect sensor. Only some low-cost resistances are used to measure the stator currents of a brushless DC motor, which is used to drive the hand-tool.
They proposed Novel 3-phase current commands to obtain greater torque than traditional 3-phase, square-wave current commands. By an experimental digital signal processor, TMS-320-F2808 that was manufactured by Texas Instruments, is used to execute the control and estimation algorithms.
It proved that the implemented electric hand-tool can set adjustable torque commands and varied driving time for different purposes, and therefore can be used in manufacturing as well as in daily life due to its low cost and functionality.
