A 3-phase BLDC motor drive reference design with Field Oriented Control (FOC) sensorless mode specifically for ceiling fan applications, supporting power up to 50 W.
A Brushless DC (BLDC) fan controller is essential for improved energy efficiency, reducing power consumption and lowering electricity costs. It enables precise speed control, allowing users to adjust fan speeds according to their specific needs and preferences. BLDC fans operate silently due to their brushless design, ensuring a noise-free environment. With a longer lifespan than traditional fans, BLDC fan controllers offer durability and reduced maintenance requirements. To address the issues, STMicroelectronics have launched a 3-phase BLDC motor drive up to 50 W, STEVAL-IHM038V1 reference design suitable for fan controllers. The design uses Field Oriented Control (FOC) sensorless mode, specifically designed for ceiling fan applications.
