The principle of reducing the rotor losses by the application of a copper cage is known in the power range of very big as well as very small machines. In this contribution a new technology of copper die-casting for standard motors is introduced which gives the possibility of loss reduction and the achievement of a higher energy efficiency class without increasing the active volume. Specifically developed copper alloys own a favorable electric conductivity at simultaneously gained mechanical yield strength. Without rise of the external dimensions a higher power density is accessible in the end. The modeling of the machine for FEA calculations, the specific features of the geometry with copper rotor and the effects on the operational parameters are presented. The development of analytical and numerical models for the description of the electromagnetic behavior includes the influence of the bar form and the slot design, the variation of the slot shape as well as the effects on initial torque and breakdown torque. Special attention is paid on the effects of the changed saturation conditions, rotor losses and additional rotor losses. The calculated data and characteristic curves are verified by measurements on a range of 15 kW standard motors. In this project phase always the same stator geometry has been used for comparability. The rotors have identical sheet cross sections with different cage material. Due to the higher efficiency and better mechanical properties new application fields are opened to the induction machine with die-cast copper rotor at middle power area especially in electric mobility and high-speed applications.","PeriodicalId":286682,"journal":{"name":"2017 International Symposium on Electrical Machines (SME)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132316854","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unfortunately, the high cost of these machines is a major barrier to increasing their market share in small-size drive units where the return on investment period is long. The high cost of equipment makes manufacturers use only one type of motor, for the effect of scale to reduce the unit production cost of the device. This complicates the implementation process of non-standard projects that are required to use higher power drive units. This paper presents a way of controlling the drive unit of a passenger elevator cabin door of non-standard width and weight. Due to the device's mechanical parameters, the use of a single motor cannot achieve the desired operating effects. The prototype system uses two drive units with PMSM motors, connected to each other by a serial bus, which transmit the data necessary for the correct operation of the system. It also provides an additional delay for the torque regulator in the master drive unit to reduce torque oscillation on the motor shafts caused by transmission delay between the master and slave unit. These assumptions were successfully examined on the real door drive system that consisted of two independent PMSM drives.","PeriodicalId":286682,"journal":{"name":"2017 International Symposium on Electrical Machines (SME)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123127120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
