Our medical ventilator motor drive solution is designed for hospital emergency rooms and ambulances. It is built around a Cortex®-A9 core board, an Arm® Cortex®-M7 processor and an FOC electronic speed controller board. The FOC ESC board is a high-performance drive board custom-built for the brushless motor used in the ventilator; its firmware is based on a specially optimized FOC algorithm, delivering energy-efficient and quiet operation, fast acceleration and deceleration, reliable start-up and multiple protection mechanisms.
