Hello... I do want to have motion contol with 3Phase induction motor with FOC algorithm. The FOC library(FOC SDK v3.2--UM1052) and software(ST Motor Control WorkBench) offered ST is for PMSM. I dont want to use Permanent Magnet motor I want to use induction motor. Its been said that UM0483 has control of ACIM but inthere is no library present for ACIM http://www.st.com/internet/com/end_application/908.jsp . Help me in this regards. Based on your reply I can stay with ST.com. Microchip company offeres Sensorless FOC for Induction Motor. I bought STM32F4 discovery and programmer from ST. I want to use ST for Induction motor since the FOC library is well established and you offered software for motor control.
