Description: Three phase brushless motors (either AC induction or permanent magnet synchronous motors)
historically owe their great success in adjustable speed application to the advent of frequency
converters and sophisticated control techniques. These high-performance drives were mainly
used for factory automation and robotics. For the last decade, the significant price decrease of
the electronics bill of material allowed them to be used in cost-sensitive markets such as
household appliances, air conditioning or personal healthcare equipment. We will discuss here
how ARM-based standard devices helped to break the complexity paradigm in a market that
was for long dominated by DSPs and FPGAs. STMicroelectronics’ STM32 product family,
based on the Cortex-M3 core, will be used as the example.
