Description

sensorless BLDC control hardware (less the microcontroller) - provides a simplified interface to a microcontroller to control a sensorless BLDC motor (such as used in R.C. craft). back EMF signals are put through a comparator and the 3-phase control signals are encoded one 3 lines rather than 6.

Currently tested using Parallax Propeller code (to be released) and various brushless motors in the 30 to 600W range.
