1.2 Benefits of sensorless stall detection in stepper motor drivers

説明

2020年 11月 5日

The ability to reliably detect the stall of a stepper motor for overload or end-of travel conditions without the aid of external sensors has long been sought after in stepper drive systems. By detecting back-emf phase shift between rising and falling current quadrants of the motor current, learn how stepper devices from Texas Instruments can detect a motor stall that is independent of changes in motor current, motor winding resistance, ambient temperature, and supply voltage.
