Abstract

This paper describes a digital sensorless drive of permanent magnet brushless DC (PM BLDC) motors. The sensorless drive adopts a digital filter - moving average finite impulse response filter for accurate estimation of commutation time. Experimental results show that the performance of the proposed sensorless drive is superior to that of the sensorless drive without filtering.
