STEVAL-IHM031V1
Description
The STEVAL-IHM031V1 demonstration board is
designed to drive a low voltage/low-to-medium
current, 3-phase brushless, synchronous or
asynchronous motor. It provides a compact
solution along with efficient power dissipation
thanks to dual in-package power MOSFETs.
This demonstration board integrates the following
functional blocks: dedicated power supply for
handling bus voltage in the range of 12 V to 24 V
(up to 5 A), integrated gate driving, overcurrent
protection, overvoltage and overtemperature
sensing, three-shunt current sensing for FOC
control, single-shunt sensing for trapezoidal
control, BEMF sensing and amplification (for both
GE and STMicroelectronics methods) and motor
control connector.
The on-board MC connector allows the
demonstration board to be interfaced with any
STMicroelectronics MCU control board with a
dedicated connector in order to control several
types of 3-phase motors (asynchronous, PMSM
brushless DC and brushless AC).
