STMicroelectronics P-NUCLEO-IHM001

Overview

P-NUCLEO-IHM001 from STMicroelectronics is a motor control evaluation kit comprising the X-NUCLEO-IHM07M1 three-phase BLDC/PMSM driver board, NUCLEO-F302R8 STM32F302R8-based controller board, and Bull-Running BR2804-1700 kV motor. It supports sensorless and sensor-based FOC or 6-step control, operates at 8–48 V DC, delivers up to 2.8 A peak output current, and integrates non-dissipative overcurrent protection for low-voltage, low-current motor prototyping.

For engineers reviewing the P-NUCLEO-IHM001 datasheet, P-NUCLEO-IHM001 pinout, P-NUCLEO-IHM001 application, or P-NUCLEO-IHM001 equivalent, this kit enables rapid validation of field-oriented control algorithms, shunt-based current sensing configurations (1-shunt or 3-shunt), Hall encoder interfacing, and real-time motor speed regulation via onboard potentiometer - all on an mbed-enabled, ST-LINK/V2-1 integrated platform.

Technical Context

The system implements closed-loop motor control using the STM32F302R8 MCU (ARM Cortex-M4, 72 MHz, FPU, 64 KB Flash) executing ST's proprietary FOC or 6-step firmware, while the L6230-based X-NUCLEO-IHM07M1 provides gate driving, overcurrent detection, thermal shutdown, and configurable current-sense topology. The MCU communicates with the driver via GPIO-controlled PWM and status signals, with analog inputs for shunt voltage acquisition and Hall sensor interface pins routed to morpho headers.

Hardware-level motor control functions include non-dissipative overcurrent protection with automatic fault latching, jumper-selectable 1-shunt/3-shunt sensing, Hall encoder input support, and potentiometer-based analog speed reference - all accessible through standardized Arduino UNO R3 and ST morpho expansion interfaces without external debug probes.

FAQ

Does P-NUCLEO-IHM001 include a power supply?

No. P-NUCLEO-IHM001 contains only the X-NUCLEO-IHM07M1 driver board, NUCLEO-F302R8 controller board, and BR2804-1700 kV motor. A separate 8–48 V DC power source must be provided. The P-NUCLEO-IHM002 variant includes a 12 V, 2 A AC/DC adapter.

What motor control algorithms are supported out-of-the-box?

The kit ships with ST's Motor Control SDK v5.x firmware supporting sensorless FOC, Hall-sensor-based FOC, and 6-step trapezoidal control - all preconfigured for the BR2804-1700 kV motor and executable directly from the NUCLEO-F302R8 without modification.

Can I use a different three-phase motor with this kit?

Yes - the X-NUCLEO-IHM07M1 supports motors rated ≤48 V and ≤2.8 A peak current. Users must update motor parameters (pole pairs, resistance, inductance, back-EMF constant) in the firmware and verify current sense scaling and thermal limits for safe operation.

Is the NUCLEO-F302R8 board mbed-enabled?

Yes. The NUCLEO-F302R8 board is officially mbed-enabled and listed on developer.mbed.org. It supports online compilation, drag-and-drop programming, and access to community libraries for motor control, communication, and sensor integration.
