STMicroelectronics Evaluation Board for SLLIMM-Nano, STM32 for BLDC Ceiling Fan Controller

The STEVAL-IHM038V1 system evaluation board implements a BLDC/PMSM fan controller board which is based on the SLLIMM™-nano (small low-loss intelligent molded module) STGIPN3H60 and STM32F100C6T6B microcontroller. The STEVAL-IHM038V1 incorporates a complete inverter stage and a control stage to drive a 3-phase BLDC fan motor with a power range of 30-35 W with FOC (field oriented control) sensorless mode for the ceiling fan applications. For power factor correction, a passive PFC stage is implemented to achieve a power factor up to 0.90, which is the minimum recommended for ceiling fan applications, particularly for the Indian market. To set the speed by remote control, an on-board IR demodulator is available.
