Product details

Overview

P-NUCLEO-IHM03 from STMicroelectronics is an STM32-based motor-control evaluation kit comprising the X-NUCLEO-IHM16M1 three-phase driver board, NUCLEO-G431RB MCU board, GBM2804H-100T gimbal motor (14.8 V, 5 A, 2180 rpm), and 12 V/2 A AC/DC power supply. It implements Field-Oriented Control (FOC) for low-voltage, low-current BLDC/PMSM motors up to 1.5 A rms output current with BEMF sensing and shunt-based current measurement.

For engineers reviewing the P-NUCLEO-IHM03 datasheet, P-NUCLEO-IHM03 pinout, P-NUCLEO-IHM03 application, or P-NUCLEO-IHM03 equivalent, this kit enables rapid validation of FOC algorithms, sensorless/sensor-based closed-loop control, and motor-drive firmware development on STM32G4 with integrated STLINK-V3E debugging and morpho/Arduino expansion headers.

Technical Context

The kit integrates two tightly coupled hardware modules: the X-NUCLEO-IHM16M1 uses the STSPIN830 triple-half-bridge driver (QFN-24, 7–45 V, 1.5 A rms) with interlock logic, thermal shutdown, and configurable 3-shunt/1-shunt current sensing; it supports both 6-input and 3-PWM control modes via MODE pin. The NUCLEO-G431RB hosts the STM32G431RB MCU (Arm Cortex-M4 @ 170 MHz, 128 KB Flash, 32 KB SRAM) with advanced analog peripherals including high-resolution timers and ADCs optimized for real-time motor control loops.

Hardware-level coordination includes BEMF sensing circuitry on the driver board, Hall/encoder input connectors, potentiometer-based speed reference, and ST morpho headers enabling full I/O access between MCU and driver-enabling seamless implementation of FOC, 6-step commutation, and sensorless startup sequences without external signal conditioning.

FAQ

Does P-NUCLEO-IHM03 support sensorless FOC out of the box?

Yes. The X-NUCLEO-IHM16M1 board includes dedicated BEMF sensing circuitry, and the preloaded X-CUBE-MCSDK firmware on the NUCLEO-G431RB implements fully functional sensorless FOC with startup and transition handling. No hardware modification or external components are required to run the base demo.

Can the included GBM2804H-100T motor be replaced with another three-phase motor?

Yes-within electrical and mechanical limits. The STSPIN830 driver supports 7–45 V dc and 1.5 A rms continuous current. Any three-phase BLDC or PMSM motor meeting those voltage/current ratings and compatible with 3-shunt or 1-shunt current sensing can be substituted, provided BEMF characteristics or sensor interface (Hall/encoder) align with firmware configuration.

Is STLINK-V3E on the NUCLEO-G431RB capable of programming external STM32 targets?

Yes. The STLINK-V3E debugger supports SWD/JTAG and can program and debug external STM32 devices via the SWDIO and SWCLK pins on the ST morpho headers. Users must configure the target's BOOT pins appropriately and ensure proper voltage level matching between the NUCLEO board and the external target.

What software tools are required to modify the motor control firmware?

Keil MDK-ARM, IAR EWARM, or GCC-based IDEs (e.g., STM32CubeIDE) are supported. The X-CUBE-MCSDK source code-including motor parameters, FOC PI gains, and observer tuning-is provided and editable. STM32CubeMX configures peripherals; Motor Pilot GUI enables real-time parameter tuning and oscilloscope-style waveform capture over USB CDC.
