Description
STEVAL-IHM017V1
evaluation board
Data Brief
This evaluation board is a complete development
platform for BLDC sensorless motor applications
with nominal power up to 100 W.
Based on a cost effective, flexible and open
design, it includes a 3-phase inverter bridge
based on the STD5NK52ZD-1 power MOSFET in
the IPAK package and an ST7MC 8-bit
microcontroller with 16 Kbyte internal Flash
memory.
The system has been designed to drive a 3-phase
brushless motor with permanent magnet rotor
exploiting trapezoidal sensorless control.
The STEVAL-IHM017V1 features complete
hardware for developing motor control
applications based on ST7MC peripherals
including motor control peripheral (MTC). It uses
an in-circuit communication (ICC) standard
interface to connect to the host PC via in-circuit
debuggers/programmers such as the inDART-STX
board from SofTec Microsystems™. The board is
designed to support a bus voltage of 230 Vac and
up to 100 W of input power. Also included is a
power supply stage with the VIPer12A-E as the
STEVAL-IHM017V1
buck converter to generate the voltage reference
for the driver and the microcontroller.
