desc®ibes how to implement a sensorless control for single and two-phase BLDC motors using the 8-bit PIC microcontroller. The implementation is based on the low-cost PIC16F153XX family of microcontrollers and hardware BEMF filtering in a cooling fan application. The application is tested on a 80 mm x 80
