3-phase asynchronous motors demonstration board
Data Brief
■ Voltage Input range 115 V
to 230 VAC
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:
– 2-phase motor two sinusoidal voltage
waves restored with a phase displacement
of 90° between them
– 3-phase motor three sinusoidal voltages
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 washerup machines
■ High efficiency transfer pumps for outlet
condensation water in gas furnace application
AM01597v1
STEVAL-IHM019V1
where high efficiency is required and low cost per
solution is a must.
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
