STMicroelectronics STEVAL-IHM008V1

Overview

STEVAL-IHM008V1 from STMicroelectronics is a 1 kW three-phase inverter reference design board for BLDC, AC induction, and BLAC permanent magnet motor control, featuring a STG3P2M10N60B SEMITOP®2 IGBT module, six-step and sinusoidal PWM outputs, and integrated high-side/low-side gate drivers with protection functions.

For engineers reviewing the STEVAL-IHM008V1 datasheet, STEVAL-IHM008V1 pinout, STEVAL-IHM008V1 application, or STEVAL-IHM008V1 equivalent, this board supports rapid prototyping of sensorless BLDC (6-step), Hall-sensored BLAC (sinusoidal), and 3-phase AC induction motor drives with low-noise layout and ORCAD source file availability.

Technical Context

The board implements a full-bridge inverter topology using a monolithic SEMITOP®2 600 V / 10 A IGBT module with integrated mono-phase rectifier input stage and three-phase output stage. Gate driving is handled by three dedicated high-voltage, high-side/low-side drivers providing shoot-through protection and fault reporting.

Power supply is derived from a VIPer53 high-voltage offline regulator IC delivering stable +15 V and +5 V rails. Control logic resides on a plug-in ST7FMC MCU board, enabling flexible commutation schemes including six-step trapezoidal and sine-wave-modulated PWM with Hall sensor or back-EMF sensing.

FAQ

Is STEVAL-IHM008V1 a standalone motor controller?

No. It is a power stage reference board requiring a separate control board-specifically designed to mate with the ST7FMC-based plug-in control board referenced in the documentation. The board provides only inverter, gate drive, and power supply functions; no MCU or firmware is onboard.

What motor connection interfaces does it support?

It provides screw-terminal blocks for 3-phase motor output (U/V/W), Hall sensor inputs (H1/H2/H3), DC bus voltage monitoring, and analog speed reference input. Motor phase current sensing is implemented via shunt resistors with differential amplifiers routed to the control board ADC inputs.

Can it operate from single-phase 230 V AC mains?

Yes. The onboard VIPer53-based SMPS accepts 230 V AC ±15% input and delivers regulated +15 V and +5 V. The SEMITOP®2 module's rectifier stage converts AC input to ~325 V DC bus, enabling direct connection to standard European mains without external transformer or PFC stage.

Are ORCAD schematic files still available for this board?

Yes. STMicroelectronics officially released the complete ORCAD design files-including schematics, PCB layout, and BOM-for free download via its legacy product archive (document DB2492). These files remain accessible for educational use and derivative design under ST's evaluation license terms.
