Fairchild's BLDC/PMSM motor controller with parallel processing cores provides simple conversion of AC motor control designs

USA: Motor control application designers are now moving away from the traditional universal or AC motor design to a more sophisticated brushless DC (BLDC) motor or permanent magnet synchronous motor (PMSM) design.

However, choosing either of these methods can be challenging if the designer has limited access to advanced, complex motor control algorithms. This can lead to significant spending of research and development resources and longer design times.

To help designers with these cost and software burdens, Fairchild Semiconductor has developed the FCM8531 analog and digital integrated motor controller. The FCM8531 is a tailored configurable solution complete with user guides, reference designs, and evaluation boards that help motor control designers shorten time-to-market and minimize software design efforts.

The FCM8531 is a three-phase, hybrid BLDC/PMSM controller with two parallel processors – an advanced motor controller (AMC) and an embedded microcontroller (MCU) – that provides a complete, one-chip solution for complex motor control applications.

The two core processors work independently but collaboratively to exchange data through an internal communications interface that helps to avoid system hang-ups and improves hardware protection. The FCM8531 minimizes the software burden with its integrated hardware controller and MCU interface management and achieves a fast load-response motor system with increased efficiency.
