Applications

Description

The STEVAL-IHM032V1 demonstration board is a

3-phase inverter designed to perform both the

field-oriented control (FOC) of sinusoidal-shaped

back-EMF permanent magnet synchronous

motors (PMSMs) and trapezoidal control of

brushless DC (BLDC) motors with or without

sensors, with nominal power up to 150 W.

This flexible, open, high-performance system

based on the L639x and STGD3HF60HD is

specifically designed to achieve fast and accurate

conditioning of the current feedback, thereby

matching the requirements typical of high-end

The board is compatible with 110 and 230 Vac

mains, and includes a power supply stage with

the VIPer12A-E (in flyback configuration) to

generate the +15 V and +3.3 V supply voltage

required by the application. Finally, the board can

be interfaced through a dedicated connector with

the STM3210xx-EVAL (STM32 microcontroller

demonstration board), STEVAL-IHM022V1 (high-

density, dual motor control demonstration board

based on the STM32F103ZE microcontroller),

and with the STEVAL-IHM033V1 (control stage

based on the STM32F100 microcontroller suitable

for motor control).
