P-NUCLEO-IHM03

P-NUCLEO-IHM03 is a STM32 motor-control pack using FOC algorithm for 3-phase, low-voltage and low‑current motor evaluation. This motor-control kit is based on the X-NUCLEO-IHM16M1 and NUCLEO-G431RB boards. Used with STM32 Nucleo board through ST morpho connector, the power board provides a motor-control solution for 3-phase, low-voltage, PMSM motors. The STSPIN830 device on power board is a compact and versatile FOC-ready driver for 3-phase motor. It supports both single-shunt and 3-shunt architectures and embeds PWM current controller with user-settable values of reference voltage and off time. With a dedicated mode I/P pin, device offers freedom to decide whether to drive it through 6 inputs or more common 3 PWM directly driven I/P. In addition, it integrates both control logic and fully protected low-RDS(on), triple-half-bridge power stage. The NUCLEO-G431RB control board provides an affordable and flexible way for users to try out new concepts and build prototypes with STM32G4 MCU.
