Data brief

STEVAL-IHM023V1

AM05056v1

Description

The STEVAL-IHM023V1 is a demonstration board
designed to implement general purpose low
power 3-phase inverter for 3-phase asynchronous
motors, bi-phase AC motors or PMAC motors up
to 1000 W.
It is fully equipped and convenient for evaluating
customers solution in applications like: drum
motor control for washing machine, power white
goods application, medical beds, water pump for
home appliance white goods, transfer pumps for
waste sludge – sewerage plants and high
efficiency transfer pumps for outlet condensation
water in gas furnace application.
