Abstract
When BLDC drive mode is used to drive PM-AC motors, the influence of the transient current cannot be neglected, especially during high speed operation. In this paper, this influence to the BLDC drive mode is analyzed, and an analytic model for describing the transient current to the commutation angle and copper loss is presented. A method to determine the optimal commutation angle of the BLDC mode is introduced. Both the simulation and testing results prove the effectiveness of the model and the method.
