STM32 Motor Control

For 3‑phase brushless motor vector drives.

STMicroelectronics’ STM32 offers the performance of the industry‑standard Cortex™‑M3 core at the service of vector (or field‑oriented) control algorithms. Vector‑control algorithms are widely used in high‑performance drives. They provide precise and responsive torque and speed control, and guarantee optimized efficiency during transient operations. Practically, they also have the advantage of using the same framework to control an asynchronous or synchronous motor. This is interesting for development teams that have to deal with various applications and motor types. Finally, the sensorless algorithms for rotor speed and position detection are also of interest when trying to reduce the cost of the drive.

STM32L EnergyLite

The STM32L MCU family, based on the Cortex-M3 core, extends ST’s ultra-low-power portfolio in performance, features, memory size and package pin count. It combines very high performance and ultra-low power consumption, through the use of an optimized architecture and our proprietary ultra-low leakage process, shared with the STM8L family. The STM32L family offers two different lines (STM32L151 and STM32L152) so optimizing the STM32F and STM8L families for many applications requiring performance with special care on power savings.
