MCUs for Motor Control
More InfoLess Info
This paper describes the most popular types of three-phase motors and the control methods that suit each type, then explains how special-purpose MCU functions can simplify application development. Designers who begin with an understanding of general-purpose MCUs can thus gain the knowledge needed to take advantage of today's MCU-based application-specific standard products (ASSPs) for three-phase motor control. The motor-control methods described here apply to any application that uses three-phase pulse-width modulation (PWM).
