Description
This demonstration board, in terms of hardware
and software, is ready to use in the development
of universal motor driving based on phase angle
control.
This board implements a traditional design
solution for a universal motor control circuit with a
microcontroller as a driver.
The STEVAL-IHM013V1 has been customized for
vacuum cleaner applications, however it can be
easily adapted for most home appliance or
industrial applications based on phase angle
control without speed closed loop control.
The electronic driver with TRIAC and
microcontroller is cost effective and easy for
designers to implement. Analog solutions are
being progressively replaced by microcontroller
designs even in low-cost applications. The main
reason of this evolution is primarily due to the
possibility to of implementing a soft-start function
which allows the equipment to fulfill IEC 61000-3-
3 standard on inrush currents.
Their advantages also include flexibility, using
less external components and easy adaptation by
simple software modifications.
