Fairchild Semiconductor (San Jose, CA) has released the FCM8531 analog and digital integrated motor controller. The 3-phase, hybrid BLDC/PMSM controller offers two parallel processors — an advanced motor controller (AMC) and an embedded microcontroller (MCU) — that provide a one-chip solution for complex motor control applications. The two core processors exchange data through an internal communications interface.
The AMC performs algorithms such as sine wave control, field oriented control (FOC), and direct and quadrature (DQ) control using the company’s libraries that can be configured and stored. The MCU interface, paired with the AMC, enables users to change the register values for different motor operation flows and characteristics. The motor control development system consists of an integrated development environment and a MCDS programming kit that allows engineers to configure the AMC and develop codes for the MCU.
