STMicroelectronics STEVAL-IHM040V1

Overview

STEVAL-IHM040V1 from STMicroelectronics is a 3-phase BLDC/PMSM motor driver demonstration board based on the STM32F100C8T6 microcontroller and STGIPN3H60 SLLIMM-nano intelligent power module, supporting both six-step and field-oriented control (FOC), with 115/230 VAC or 150–350 VDC input, and 0.5 ARMS continuous motor output current for industrial motor control prototyping.

For engineers reviewing the STEVAL-IHM040V1 datasheet, STEVAL-IHM040V1 pinout, STEVAL-IHM040V1 application, or STEVAL-IHM040V1 equivalent, this board enables rapid validation of sensorless or Hall-based motor control algorithms, power stage thermal behavior, gate drive timing margins, and embedded firmware integration with SLLIMM-nano IPMs in low-voltage industrial drives.

Technical Context

The board implements dual-motor-control firmware-six-step commutation and FOC-running on the STM32F100C8T6, which provides PWM generation, ADC-based current sensing, and real-time control loop execution. The SLLIMM-nano STGIPN3H60 integrates six 600 V IGBTs, gate drivers, level shifters, hardware overcurrent shutdown, and an op-amp for current-sense signal conditioning.

Power conversion includes VIPER16-based high-voltage DC-DC conversion to 15 V for the SLLIMM and analog circuitry, plus an L78L33 linear regulator delivering 3.3 V for the MCU. Isolated SWD debugging (SWDIO/SWCLK/NRST) and onboard potentiometer enable runtime parameter tuning without host PC reflash.

FAQ

Does STEVAL-IHM040V1 support Hall-effect sensor feedback?

Yes. The board includes three Hall-effect sensor inputs (BEMFA/BEMFB/BEMFC) routed to PA0–PA2 on the STM32F100C8T6, enabling six-step commutation with position feedback. Firmware supports both Hall-based and sensorless operation, and the schematic shows dedicated RC filtering and biasing networks for each channel.

What is the maximum motor voltage rating supported by the STGIPN3H60 on this board?

The STGIPN3H60 is rated for 600 V blocking voltage and operates safely up to 350 VDC bus voltage, as confirmed by the board's documented DC input range (150–350 VDC) and layout clearance design per IEC 61800-5-1. Derating is applied for AC mains transients per EN 61000-4-5.

Can the onboard 3.3 V supply power external peripherals?

Yes-the L78L33 delivers up to 100 mA at 3.3 V, sufficient for low-power peripherals like Hall sensors, optocouplers, or logic-level interface ICs. The schematic shows dedicated decoupling (C1, C2) and routing separate from MCU core power, minimizing noise coupling into analog or control paths.

Is FOC firmware provided with source code or only as compiled binary?

ST provides full source code for both six-step and FOC firmware in the official UM1493 user manual, including CMSIS-based motor control library, configuration headers, and startup files compatible with Keil MDK and GCC toolchains. No license restrictions apply for evaluation and derivative design use.
