with phase displacement of 120° among
them
STEVAL-IHM019V1
where high efficiency is required and low cost per
solution is a must.
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
