Abstract

In this paper, a novel Sensorless Commutation method for BLDC motors is presented to eliminate simultaneously phase shifter and low-pass filter. An analytical model of the motor is presented, and the ripples resulted from the current commutation are investigated in details. By detecting the zero crossing points of the unfiltered voltages of the motor terminals with regard to the ground and to the DC link, the commutation signals can be generated using a set of proposed logical equations. The extracted commutation points are phase delay-free, because the low-pass filters have been eliminated. Therefore, the proposed method can be used in a wide range of speeds. Moreover, the method is cost-effective because it does not need any Phase Shifters. Simulation and real-time implementation results show the effectiveness of the proposed method.
