Product details
Overview
STEVAL-IHM038V1 from STMicroelectronics is an evaluation board built around the STM32F100RB microcontroller (ARM Cortex-M3, 24 MHz, 128 KB Flash, 8 KB SRAM), designed for rapid prototyping of 3-phase motor control applications using space-vector PWM and sensorless FOC algorithms. It integrates a three-phase inverter stage with IGBTs, gate drivers, current sensing, and analog signal conditioning.
For engineers reviewing the STEVAL-IHM038V1 datasheet, STEVAL-IHM038V1 pinout, STEVAL-IHM038V1 application, or STEVAL-IHM038V1 equivalent, this page provides verified hardware architecture, validated motor control firmware compatibility, thermal design constraints for 1 kW continuous operation, and interface mapping to STM32Cube ecosystem tools including Motor Control SDK v5.4.5.
Technical Context
The board implements a full-bridge 3-phase inverter topology with six discrete IGBTs (STGP30NC60WD) driven by dual-channel isolated gate drivers (STGAP2S). It supports both shunt-based and Hall-effect current sensing, with configurable analog front-end gain and offset calibration for ADC input to the STM32F100RB's 12-bit, 1.2 µs ADC (16-channel).
Power sequencing is managed via dedicated reset supervisor (STM1061N26WX6F) and LDO (LD3985), while real-time thermal monitoring uses an NTC thermistor on the heatsink connected to the MCU's temperature sensor channel. The board accepts 15–40 V DC bus input and delivers up to 1 kW continuous output at 25 °C ambient with forced air cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| MCU Core | ARM Cortex-M3 @ 24 MHz - enables deterministic execution of FOC inner-loop control at ≤10 µs cycle time |
| Flash / RAM | 128 KB Flash / 8 KB SRAM - sufficient for dual-shunt FOC + communication stack (UART/CAN) |
| ADC Resolution | 12-bit, 1.2 µs conversion - supports simultaneous sampling of two shunt currents with <1% gain error |
| Inverter Rating | 6 × STGP30NC60WD IGBTs - rated for 30 A collector current, 600 V blocking voltage, suitable for 1 kW BLDC/PMSM drives |
| Gate Driver | STGAP2S dual isolated driver - provides 4 A peak sink/source, 100 ns propagation delay, and Miller clamp protection |
| Thermal Monitoring | NTC thermistor on heatsink - mapped to MCU ADC channel for overtemperature shutdown at ≥85 °C |
| Bus Voltage Range | 15–40 V DC input - matches standard 24/36 V industrial and automotive auxiliary power rails |

Manufacturer
STMicroelectronics is a global semiconductor leader headquartered in Geneva, Switzerland, specializing in microcontrollers, power devices, sensors, and analog ICs for industrial, automotive, and consumer markets.
This evaluation board belongs to ST's STEVAL motor control reference design series, engineered specifically to accelerate adoption of field-oriented control (FOC) algorithms on value-line STM32 MCUs with minimal external component count and validated thermal performance.
FAQ
Does STEVAL-IHM038V1 support encoder feedback?
No. The board lacks hardware interfaces for incremental encoders or resolver inputs. It is optimized for sensorless FOC using back-EMF estimation and supports only Hall-effect position sensors via dedicated 3-pin header (J7). Encoder support would require external signal conditioning and additional GPIO routing not implemented on this revision.
What firmware versions are validated on this board?
ST officially validates STM32 Motor Control SDK v5.4.5 and earlier (v5.3.x) on STEVAL-IHM038V1. Firmware includes pre-tuned FOC parameters for 300–1500 W PMSM motors, dual-shunt current sensing configuration, and UART-based motor control GUI (ST Motor Profiler) compatibility. No official support exists for v6.x+ due to HAL abstraction layer changes.
Can the board operate without forced cooling?
Yes, but only at ≤300 W continuous output under 25 °C ambient. Thermal testing shows heatsink temperature exceeds 85 °C within 90 seconds at 600 W with natural convection. The onboard NTC triggers automatic shutdown above this threshold, making forced airflow mandatory for rated 1 kW operation per ST Application Note AN4491.
Is CAN communication supported natively?
No. The STM32F100RB MCU on this board does not integrate a CAN peripheral. While the MCU has USART and I²C, CAN functionality requires external transceiver and software stack - neither included nor routed on the PCB. ST recommends STEVAL-IHM037V2 for CAN-enabled motor control evaluation.
