外文摘要：To improve the flux-weakening capability of a brushless DC motor (BLDC) with trapezoidal wave, here is a 120 degrees conduction square wave control stratgey. In this paper, a novel current integrated vector control strategy is proposed based on stator current prime vector. The vector control mode controls amperages that flow through the vertical and straight axes of BLDC under rotor flux orientation reference axis system and regulates the speed by combination with voltage vector modulation. A BLDC vector control system including flux-weakening control is built. In the end, in the simulation system for the 120 degrees BLDC vector control, it is proved that the current integrated vector control strategy has a good control effect and realizes the flux-weakening control of the BLDC at the base speed or above.
