L99ASC03 Fully-Integrated Motor Driver IC for Three-Phase Brushless Motors
STMicroelectronics
This presentation will begin by offering a general overview of permanent magnet machines and three-phase brushless motors, followed by some discussion around controlling these motors and the working mechanics of back-EMF detection. That will lead up to describing some of the features and the benefits of the L99ASC03, which is based on sensor-less driving of a three-phase brushless motor.
