Investigation of Control Methods for Segmented Long Stator Linear Drives

摘要: Nowadays, linear motors are widely used in machine tools to eliminate the gear re-lated problems of rotative drives with lead-screw transmission. With performance increases considerably since mechanical transmission elements re-moved. This leads a better precision, higher acceleration and speed moving part. Therefore, direct increasingly indus-trial applications although these solutions often need investment costs. In industrial processing plants, raw materials transferred into production process, typically then they pass several stations finally, processed article is removed from chain. today’s different equipment for transportation materials. Advantages can be ex-pected by using same system as well proc-essing Hence, this dissertation discusses proposal process-integrated material handling based on drives. The integration pro-duction plant calls new view process. integrative viewpoint where co-design drive introduced should developed future appli-cations. To fulfill demand system, two alternatives compared. first one active vehicles passive tracks second tracks. disadvantages both discussed, considering aspects power supply control communication demands.
