摘要 介绍了一种基于瞬时无功功率理论的永磁无刷直流电动机弱磁调速新策略,通过控制无功分量s/ω达到弱磁的效果。仿真结果表明,与传统的弱磁方法相比,该方法最大的优点是能够提高弱磁调速范围,减少了转矩脉动。 A novel field-weakening scheme for brushless DC motors based on instantaneous reactive power theory is introduced in this paper.In practice, increasing s/ω has a field-weakening effect and results in increased motor speed. Simulation results show that the overall of this method is the enhancement of field-weakening performance of drive and a reduction in torque ripple compared the conventional method.
