To select and optimize the optimum motor for handheld industrial power tools, we need to first review the motor technology. Let’s consider Brush and Brushless DC motors as our primary selections.
Battery powered industrial power tools run on low voltage (12-60 V). Brushed DC motors are typically a good economical choice, but the life of operation of the motor will become an issue. The brushes will see wear because of electrical (due to the current related to torque) and mechanical (due to the friction related to speed) factors, limiting the number of cycles until end of life is reached.Brushless DC motors are a more reliable motor solution. They are less susceptible to mechanical wear (no brush friction) and can sustain high peak current (no brushes) during the tightening phase, providing far greater life in the hand tool.Brushless DC motors are better suited than brush DC for industrial power tool applications since they require high speed and high peak current.
