    Abstract
  • This paper analyzes the relation between commutation position of brushless direct current (BLDC) motors and bus current, builds up their mathematical relation, and proposes a sensorless BLDC motors commutation position optimization strategy. This strategy regulates the commutation position by a proportional integral (PI) adjuster, aiming at regulating the current and the back electromotive force (BEMF) in-phase. The controlled variable of the PI adjuster is the commutation position compensating angle and the deviation value is the ratio of current change over angle. This optimization strategy can revise the detected position signal error and the phase deviation caused by the winding inductance at the same time. The experimental results verify that this optimization strategy can get the best commutation position accurately and fast, and improve the operating efficiency effectively.
