STEVAL-IHM017V1
100 W 3-phase inverter for BLDC sensorless motor evaluation board
Data Brief

Features

Wide range input voltage Maximum power up to 100 W 4.4 A, 520 V power MOSFET included Compatible with power MOSFETs in IPAK packages 15 V auxiliary power supply connector Programming and debugging support via 10pin ICC connector Three potentiometers for runtime settings Start/stop button Reset button

Description
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 MicrosystemsTM. 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.
