STEVAL-IHM035V2 3-phase high voltage inverter power board for FOC and scalar motor control based on the STGIPN3H60 (SLLIMM™-nano) Data brief Description The STEVAL-IHM035V2 is designed to drive a high voltage/low power 3-phase brushless motor, either synchronous or asynchronous (PMSM and ACIM). It provides a compact solution in terms of size and efficient power dissipation, thanks to the ST IPM STGIPN3H60 (SLLIMM™-nano). With the on-board MC-connector, the demonstration board can also be interfaced with any ST MCU control board in order to implement a complete motor drive.
