Strategies to reduce a 3-Phase BLDC motor control and drive system

摘要

Highly integrated semiconductor products are not only a trend in consumer products, but also in motor-control applications. Concurrently, the share of Brushless DC (BLDC) motors is gradually increasing over other motor types in a number of markets, such as automotive and medical applications. With the demand growth and mature technology of BLDC motors, the strategies to develop BLDC motor-control systems have evolved from discrete circuits into three distinct categories. These primary approaches can be classified as systems on chip (SoCs), application-specific standard products (ASSPs), and two-chip Solutions.
