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.
