摘    要:无刷直流电机导通相换相断开后在非换相区间有无电流对电机性能有重要的影响.本文根据无刷直流电机的工作原理,通过建立无刷直流电机的简化等效模型,揭示了无刷直流电机断开相电流产生的条件和计算方程,给出了不同脉宽调制方式断开相电流出现的规律,并进行了实验验证.结果表明:当断开相反电动势小于零,上管为脉宽调制、下管为恒通时或当断...

关 键 词:无刷直流电机  断开相电流  脉宽调制  断开相反电动势

Abstract:whether there is current at non-commutation duration when the energized phase of brushless DC turns into floating phase affects the motor's operating performance greatly.Based on the working principle of brushless DC motors,This paper presents a simplified equivalent model for brushless DC motors,and reveals the conditions and calculation equation when current is generated in the floating phase of brushless DC motors.It puts forward the law of generated current in the floating phase in different pulse-width...
Keywords:Brushless DC motor  floating phase current  pulse width modulation  back electromotive force for floating phase
