Design Platform for Motor Drives

altSTMicroelectronics (Geneva, Switzerland) offers new resources for users to simplify design and speed up development of intelligent motor drives for applications such as white goods, air conditioners, industrial automation, power tools and fitness equipment. Electric motors operated by traditional on/off drives consume as much as 50% of the world’s electricity. Intelligent drives enable improved energy ratings, but present complex design challenges and historically have required expensive processors such as digital signal controllers. ST’s advanced STM32 microcontroller family and ready-to-use firmware building blocks for intelligent drives help designers overcome these challenges.

The STM32 FOC PMSM SDK v3.0 motor-control firmware library release adds support for the low-cost STM32 Value Line series (STM32F100x), enabling designers to realize intelligent drives at lower price points for highly cost-sensitive applications. It also targets the STM32 Performance Line High-Density series (STM32F103xx), exploiting the large program Flash memory combined with the advanced peripheral offering, to implement a dual-motor drive in a single controller, saving cost, size and development time. This is the first ST library to support dual motor controls and will benefit designers of equipment such as air conditioning units, industrial automation and robotics systems.
