STM32 NUCLEO Pack FOC和六步马达控制平台P-NUCLEO-IHM001
STM32 Nucleo Pack FOC and 6-step motor control platform for 3-phase low voltage motor The STM32 NUCLEO Pack (P-NUCLEO-IHM001) is a motor control kit based on X-NUCLEO-IHM07M1 and NUCLEO-F302R8 boards. This platform provides a motor control solution for low voltage three-phase DC brushless motor. It is based on L6230 driver (belonging to STSPIN family) and on STM32F302R8 MCU. The L6230 driver is a DMOS fully integrated device for three-phase brushless PMSM motor, with integrated overcurrent and thermal protection.
The STM32F302R8 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 72 MHz and embedding an advanced analog peripheral set.The X-NUCLEO-IHM07M1 board is fully configurable and ready to support different closed loop control, FOC or 6-step, based on sensorless or sensor mode, and it is compatible with three shunts or single shunt for current sense measuring.The NUCLEO-F302R8 board provides an affordable and flexible way for users to try out new concepts and build prototypes with STM32 MCU.An external power supply (8 V min; 12 V max) is required to power the kit. It does not require any separate probe as it integrates the ST-LINK/V2-1 debugger and programmer.
