交流風扇(單相)大型排風扇內 部結構是由兩個線圈繞組組成的,一個是啓動繞組,一個是運行繞組,這兩個繞組相互串聯,這樣就形成了三個點,串聯點爲公共端,啓動繞組末端爲啓動端運行繞 組末端爲運行端,交流電機還需要一個啓動電容器,通常容量爲1—2uf之間,耐壓通常是250v,這是指正常使用的市電交流電機,這種電容器是滌綸電容, 沒有正負極之分,有兩個廠房悶熱接頭,一頭接啓動繞組的末端,一頭接運行繞組的末端,形成三角式,電源(不需要區分火線零線)一條接運行繞組末端(即和電容器的一頭也接在一起),另一條接公共端,接地線就接電機外殼了;通常單相交流電機的啓動通風設備繞組也可以作爲運行繞組,果運行繞組跟啓動繞組對調的話(也就是電源的一頭接公共端的不變,接運行端的改接到啓動端,這樣就是用啓動繞組作爲運行繞組了),電機就會産生反轉了,這也是實現改變單相交流電機轉向的唯一方法!

powder metal-Go Speedy With Selective Laser Sintering
Machine maintenapowder metalnce, oiling, operating woes and drones of a factory! Well, these words may be frustrating for those who are associated with it。 Stop worrying about the same and welcome to a new age of SLS that means selective laser sintering。 So what is this new type of technology? It is a very simple processsintered metal。 In the process of SLS a very high powered laser acts on a variety of powdered materials like metal or glass and forms it into a 3D object as defined by a computer aided design。 So basically, this process involves a high powered laser changing the state of certain materials to form an object。
