MD1型電動葫蘆除起升電動機換成雙速電機組外

，其它部分與CD型xing電dian動dong葫hu蘆lu相xiang同tong。電dian機ji組zu由you主zhu起qi升sheng電dian動dong機ji，慢man速su起qi升sheng電dian動dong機ji和he慢man速su驅qu動dong裝zhuang置zhi組zu成cheng。主zhu起qi升sheng電dian機ji工gong作zuo時shi，由you於yu慢man速su起qi升sheng電dian機ji不bu接jie電dian處chu於yu製zhi動dong狀zhuang態tai，慢man速su驅qu動dong裝zhuang置zhi不bu工gong作zuo

，起qi升sheng電dian機ji後hou端duan蓋gai作zuo用yong，慢man速su起qi升sheng電dian機ji工gong作zuo時shi，慢man速su驅qu動dong裝zhuang置zhi帶dai動dong主zhu起qi升sheng錐zhui形xing轉zhuan子zi旋xuan轉zhuan，此ci時shi，主zhu起qi升sheng電dian機ji不bu工gong作zuo，風feng扇shan製zhi動dong輪lun起qi離li合he器qi作zuo用yong

，整zheng個ge機ji構gou靠kao慢man速su起qi升sheng電dian機ji的de製zhi動dong器qi製zhi動dong，這zhe樣yang就jiu產chan生sheng了le兩liang種zhong起qi升sheng速su度du。
