STEVAL-IHM031V1

3-phase low voltage inverter power board for FOC and

scalar motor control based on the STS8DNH3LL MOSFET

Features

MOSFETs

control

resistors

– overcurrent detection

– bus voltage monitoring

– temperature sensing

Description

The STEVAL-IHM031V1 demonstration board is

designed to drive a low voltage/low-to-medium

current, 3-phase brushless, synchronous or

asynchronous motor. It provides a compact

solution along with efficient power dissipation

thanks to dual in-package power MOSFETs.

This demonstration board integrates the following

functional blocks: dedicated power supply for

handling bus voltage in the range of 12 V to 24 V

(up to 5 A), integrated gate driving, overcurrent

protection, overvoltage and overtemperature

sensing, three-shunt current sensing for FOC

control, single-shunt sensing for trapezoidal

control, BEMF sensing and amplification (for both

GE and STMicroelectronics methods) and motor

control connector.

The on-board MC connector allows the

demonstration board to be interfaced with any

STMicroelectronics MCU control board with a

dedicated connector in order to control several

types of 3-phase motors (asynchronous, PMSM

brushless DC and brushless AC).
