中文摘要 | 在工業應用上及家電用品中為提高設備之可控性,而大量使用電力電子元件,但 卻造成諧波電流污染源的產生。此諧波電流流入電力系統將導致電壓源的畸變,感應電動機 經由此畸變之電壓源受電,不僅在氣隙中感應出諧波脈動轉矩,亦會產生轉子諧波轉矩。諧 波脈動轉矩通常會導致軸之扭轉振動,此外當系統的自然頻率與轉子諧波轉矩頻率相當接近 時,扭轉振動的振幅會逐漸變大,導致扭轉共振的產生,造成軸機構的迅速惡化。在本論文 中主要是分析由轉子諧波轉矩導致扭轉共振和諧波脈動轉矩導致扭轉振動的現象,並且特別 強調系統的自然頻率必須遠離整數倍的諧波頻率、諧波脈動轉矩頻率及馬達轉速。 |
英文摘要 | An increasing number of industrial control applications and home appliances employ power electronic devices which cause large concomitant harmonic currents. These harmonic currents distort the waveform of the voltage source and, in doing so, the distorted voltage can induce harmonic pulsating torque in the air gap and rotor harmonic torque of an induction machine. This harmonic pulsating torque generally causes torsional vibration. In addition, when the natural frequency of the mechanical system is in the proximity to the frequency of the rotor harmonic torque, the magnitude of the vibration becomes amplified and deteriorates rapidly; the torsional resonance occurs as well. In this investigation, we analyze the phenomena oftorsional resonance caused by rotor harmonic torque and torsional vibration caused by harmonic pulsating torque. |
