STEVAL-IHM019V1 Complete inverter for low power 3-phase asynchronous motors demonstration board Data Brief Features Voltage Input range 115 V to 230 V AC AC 50 Hz or 60 Hz Total output power 50 W High efficiency Switching PWM frequency 12 - 22 kHz Compliant with EN61000-6-3 and EN61000-6-2 Possibility to use two motor types: AM01597v1 2-phase motor two sinusoidal voltage STEVAL-IHM019V1 waves restored with a phase displacement of 90 between them where high efficiency is required and low cost per 3-phase motor three sinusoidal voltages solution is a must. with phase displacement of 120 among them Applications Water pumps for heating systems in single- family houses High efficiency surplus water pump for home appliance white goods, like washing or washer- up machines High efficiency transfer pumps for outlet condensation water in gas furnace application Description This 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 - standard single phase connecting. This 3- AC 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, but with certain modification of software it can be used also for 3-phase asynchronous motors November 2008 Rev 1 1/4 For further information contact your local STMicroelectronics sales office. www.st.com 4Circuit schematic STEVAL-IHM019V1 1 Circuit schematic Figure 1.
