DescriptionThis demonstration board implements a 3-phase inverter for low power asynchronous electric motors or permanent magnet AC motors up to 50 W. Nominal input voltage for inverter is 230 V AC - standard single phase connecting. This 3-phase inverter is based on 8-bit ST7FMC motor control controller. Main target of this demonstration board is a very low-cost effective 3-phase inverter for permanent magnet AC motor, used also for 3-phase asynchronous motors where high efficiency is required and low cost per solution is a must.
