The Q3BYG806MB three-phase hybrid stepper driver is a two-phase all-digital hybrid stepper motor driver based on AC servo principle control. It is a new generation of all-digital stepper motor driver that combines advanced DSP control chips and unique control circuits. This design greatly increases the degree of integration and greatly reduces the size and weight. It uses advanced current control algorithms for superior performance, low vibration, low noise, low heat and high speed and high torque output.
