    摘要:

    將新型開關(guān)磁阻(SR)電動機應(yīng)用于電動汽車。以電機為振源,，分析其激振力在特定方向上的作用情況,。用解析的方法,，給出了徑向力和切向力隨時間變化的具體表達式,。分析過程中,，不僅考慮了SR電機徑向力作用,，而且考慮了切向力(轉(zhuǎn)矩波動)對整個系統(tǒng)的影響,。經(jīng)過數(shù)值分析,，得出在豎直方向上激振力的幅值與初相角有直接的關(guān)系,，并且幅值存在最大值和最小值，提出了最大值和最小值的確定方法,。通過算例,，驗證了整個分析的正確性。

    Abstract:

    New type of switched reluctance motor was applied to electric vehicle. Considering the electromotor as vibration source, stimulation of electromotor was analyzed in particular orientation. Expressions of radial force and torque variance were obtained by analytical method. During the course of system analysis of electric vehicle and SR electromotor, both radial force of SR electromotor and torque variance were considered. It was concluded that there are direct relationships between amplitude and initial phase in vertical orientation by numerical analysis. There are maximum and minimum of amplitude, and the way to ensure them was proposed. New reliable foundation was put forward to solve vibration problems of design and control of SR electromotor.
