For 3-phase brushless motor vector drives Motor control for STR750F 32-bit ARM-based MCU family For 3-phase brushless motor vector drives January 2007 www.st.com/mcu Vector control at optimum cost The STR750F is a new series of super-integrated, single-chip 32-bit ARM7-based MCUs from STMicroelectronics. The STR750F offers the performance of the industry standard ARM7TDMI 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 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 mo……
