Sewing Machine Motor Driver

SEWMCHMOTR

Motor drives precisely control speed and positioning to conserve energy and increase the lifespan of electric motors. NXP supports these trends by securing interfaces, increasing flexibility and design speed of the control stage, and reducing the size of the power stage while still increasing power density. These products must adapt quickly to different motor types and have the high accuracy needed for the most rugged systems.
