Abstract :
This paper provides an alternative method for high resolution position estimation of a BLDC motor by obtaining pulses from the hall effect sensor. This method proposes to use a fast processing time in order to achieve the best performance. In the document the development of the methodology is shown for obtaining the high resolution position. The problem is the low resolution and it is due to the hall effect sensor that only provides maximum 12 rising and falling edges in the three sensors, thus the position comes to be 12 pulses per revolution. The method is demonstrated through a simulation using the considerations for fast processing.
