STMicroelectronics STEVAL-IHM003V1

Overview

STEVAL-IHM003V1 from STMicroelectronics is a 300 W BLDC and AC motor control power driver evaluation board based on a three-phase inverter topology with IGBTs rated for 10 µs short-circuit ruggedness, supporting six-step commutation and sinusoidal PWM outputs for sensorless BLDC, AC induction, and BLAC PM motors.

For engineers reviewing the STEVAL-IHM003V1 datasheet, STEVAL-IHM003V1 pinout, STEVAL-IHM003V1 application, or STEVAL-IHM003V1 equivalent, this board enables rapid validation of motor control algorithms using ST7FMC MCU-based control, IGBT gate driving with integrated high-side/low-side functionality, and Viper-based auxiliary power supply.

Technical Context

The board implements a modular inverter stage with six short-circuit rugged IGBTs, driven by three integrated high-side/low-side gate drivers located on the plug-in control board. It supports both six-step trapezoidal and sine-wave-modulated PWM output modes for precise motor phase timing and torque control.

Power delivery uses ST's Viper vertical intelligent power regulator for auxiliary supply generation, while PCB layout is optimized to minimize signal–power coupling and EMI between control logic and high-current switching paths.

FAQ

Is STEVAL-IHM003V1 still in active production?

No-STEVAL-IHM003V1 is marked as Obsolete by STMicroelectronics per its official documentation. It remains available through authorized legacy distributors and Aetrix Electronics for design continuity, but no new silicon revisions or technical support are provided.

What control MCU is used on the associated control board?

The plug-in control board uses the ST7FMC2 series 8-bit microcontroller, specifically configured for motor control with dedicated PWM timers, ADC channels for current sensing, and Hall sensor interface logic.

Can this board drive an AC induction motor without encoder feedback?

Yes-it supports open-loop V/f control of 3-phase AC induction motors using six-step commutation or scalar PWM, though closed-loop vector control requires additional current sensing and software adaptation not included in base firmware.

Are ORCAD schematic files still accessible for this board?

Yes-ST originally released ORCAD source files for STEVAL-IHM003V1 free of charge; archived versions remain available via ST's legacy design resource portals and third-party engineering repositories for schematic review and layout reuse.
