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.

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.
