摘要： A system for driving a stepper motor and adapting characteristic parameters of the stepper motor comprising a driver sub-system, responsive to control signals, for transferring power to the stepper motor. A power supply provides a driver current to the driver sub-system. A current detection device, responsive to the driver current, generates a digital feedback signal representative of the driver current. A digital processor, responsive to the digital feedback signal, generates the control signals. The digital processor is further responsive to a software algorithm to generate the control signals. These control signals provide functionality comprising detecting forces applied by the stepper motor to a load preventing a stall condition, adapting stepper motor speed and torque parameters, and limiting applied forces and driver current.
