Description
The
P-NUCLEO-IHM03
STM32 motor-control pack is a kit composed of the
X-
NUCLEO-IHM16M1
board, the
NUCLEO-G431RB
board, a brushless Gimbal motor
(GBM2804H-100T), and the DC power supply.
This platform provides a motor-control solution for three-phase, low-voltage and low-
current DC brushless or PMSM motors. It is based on the
STSPIN830
driver and on
the
STM32G431RB
MCU.

P-NUCLEO-IHM03
The STSPIN830 is a compact and versatile FOC-ready driver for a three-phase
motor. In a very small 4 x 4 mm QFN package, it integrates both the control logic and
a fully protected low-RDSon triple-half-bridge power stage. It supports both single-
and three-shunt architectures and embeds a PWM current controller based on user-
settable values of reference voltage and OFF time. Thanks to a dedicated MODE
input pin, the device offers the freedom to decide whether to drive it through 6 inputs
(one for each power switch) or a more common 3 PWM direct-driving inputs.
The STM32G431RB is a 32-bit microcontroller based on a high-performance Arm
®
Cortex
®
-M4 32-bit RISC core, with floating point unit (FPU), operating at a frequency
of up to 170 MHz, embedding an advanced analog peripheral set.
The X-NUCLEO-IHM16M1 board is fully configurable and ready to support different
closed-loop control, FOC or 6-steps, based on sensorless or sensor mode. It is
compatible with three shunts or single shunt for current-sense measurement.
The NUCLEO-G431RB board provides an affordable and flexible way for users to try
out new concepts and build prototypes with STM32G4 microcontroller. It does not
require any separate probe as it integrates the STLINK-V3E debugger and
programmer.

Product marking
Evaluation tools marked as “ES” or “E” are not yet qualified and therefore not ready to be used as reference
design or in production. Any consequences deriving from such usage will not be at ST charge. In no event, ST will
be liable for any customer usage of these engineering sample tools as reference design or in production.
“E” or “ES” marking examples of location:
•
On the targeted STM32 that is soldered on the board (for illustration of STM32 marking, refer to the STM32
datasheet “Package information” paragraph at the
www.st.com
website).
•
Next to the evaluation tool ordering part number that is stuck or silk-screen printed on the board.
This board features a specific STM32 device version, which allows the operation of any bundled commercial
stack/library available. This STM32 device shows a "U" marking option at the end of the standard part number
and is not available for sales.
In order to use the same commercial stack in his application, a developer may need to purchase a part number
specific to this stack/library. The price of those part numbers includes the stack/library royalties.
