This paper derives the equation of the particle of the elastomer , obtains the elliptical trace of the notch of the ring - type linear motor , simulates the start term of the motor and educes the theoretical start - time 0 . 5ms 推導(dǎo)了彈性體上質(zhì)點(diǎn)的橢圓運(yùn)動(dòng)方程,而后通過瞬態(tài)分析得到了長環(huán)型直線馬達(dá)上齒的端部上質(zhì)點(diǎn)的橢圓運(yùn)動(dòng)軌跡。
