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 applications such as field-oriented motor control.
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.
