摘　　要：分析了无刷直流电动机在三相六状态及不同的PWM方式下,绕组续流期间不导通相电流,并且指出各有不同。对常用的各种PWM方式通过原理分析及数学推导,得出不导通相电流存在的时段和幅值趋势。并通过实验测试,验证了分析结果。The floating phase current during the free-wheeling and the difference of the brushless DC motor operating in three-phase-six-states and different PWM modes were analysed.The conclusion of existing time and amplitude trend were achieved by theory analysis and mathematical deduction of common PWM modes.The result was verified through the experiment test.
