Designed to run on STM32 microcontrollers, the STM32 ZeST (Zero Speed Full Torque) software algorithm, allows optimum sensorless control at zero speed for any kind of permanent magnet synchronous motor (PMSM).
It runs in a seamless way with the new High-Sensitivity Observer (HSO) algorithm to control the motor in sensorless mode from very low up to high speed.
The HSO algorithm is available in the new release of the MCSDK (version 6.2). Find out more: https://www.st.com/en/embedded-softwa...
