Positioning can be accomplished by controlling the number of sequenced steps.ĭepending on the needs of a given application, Allegro IC solutions can include features such as: PWM current control Microstepping Parallel, Serial and Step/Direction interfaces Slow, Fast and Mixed current decay mode control. These steps can be sequenced together to move the rotor at various speeds corresponding to the sequence rate. When the electromagnets are supplied current in the correct polarity and sequence a torque is created that moves the rotor in steps. Stepper motor drivers are brushless DC motor drivers that can be used for both positioning and velocity control applications without the need for external position feedback.
