【摘要】 详细阐述了控制无刷直流电机运行的H/L-PWM-ON策略。此策略采用120°调制,设计较简单且占空比易于改变,其优点在于停机时能迅速反向回馈能量,达到快速停机的目的。通过相关实验,证实了该控制策略的正确性和可行性。更多还原

【Abstract】 The H/L-PWM-ON control strategy for brushless DC motor(BLDCM) was introduced in detail.It adopted 120 degree modulation.Such simple modulation could be designed easily,as well as its duty-ratio.The advantage of control strategy consist that it can feedback energy rapidly on machinehalt,according to stopping quickly.Its validity and feasibility are supported by relative experiments.更多还原
