Getting started with the X-NUCLEO-IHM07M1 motor driver expansion board
Introduction
The
X-NUCLEO-IHM07M1
is a three-phase brushless DC motor driver expansion board based on the
It provides an affordable and easy-to-use solution for driving three-phase brushless DC motor in your
The
X-NUCLEO-IHM07M1
is compatible with the ST Morpho connector and supports the addition of other boards which can be
stacked with onto a single
STM32 Nucleo
The user can also mount the Arduino UNO R3 connector. The driver used on this expansion board is the L6230, a DMOS fully
integrated driver for three-phase brushless DC motors assembled in a PowerSO-36 package (L6230PD), with overcurrent and
thermal protection.
The
L6230
driver is optimized for six-step and FOC algorithms thanks to independent current sensing.
