Transmission of rotary motions ; types of connection to gears , intermediate gears , flexible drive shafts and equipment 旋轉運動的傳動裝置.第1部分:連接齒輪中間齒輪撓
And this driving type results in the disadvantages of metro project such as the high cost of construction and maintenance , the big noise of vibration . the linear metro , which is droved by linear induction motor ( lim ) , needn ’ t intermediate gearing and is droved to advance directly by the electromagnetic thrust between primary and secondary of lim . its force of traction is no longer restricted with the track adherence and the wheel only plays the support and guidance role 電磁氣隙是直線感應電動機的一個重要參數,氣隙的變化會直接影響到電磁推力、初級電流等電機特性,而推力和電流對地鐵的穩(wěn)定運行起著至關重要的作用,所以對地鐵中直線感應電動機的性能及氣隙變化對電機性能的影響進行分析研究具有非常重要的意義。
