Abstract
A computer implemented method for controlling commutation of a brushless DC (BLDC) motor. The method includes controlling a switching array to drive the BLDC motor at a first commutation, receiving and monitoring power consumption signals indicating power consumption of the BLDC motor, determining whether the power consumption exceeds a first threshold value, and controlling the switching array to drive the BLDC motor at a second commutation when the power consumption exceeds the first threshold value.
