To assess the design technology, LSPMSM prototype was built amended from a PEIM with the same frame, stator punching and rated output. Based on the prototype test, two novel improvement designs and analyses have been done to eliminate the noise and vibration. Additionally, the comparisons with PEIM on power factor, efficiency, frame size and active material consumption indicated the significant performance improvement and active material cost down can be achieved by LSPMSM.","PeriodicalId":101507,"journal":{"name":"2011 International Conference on Electrical Machines and Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130089996","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}

Direct torque control has some benefits such as faster torque response and reduced torque ripple for driving the brushless DC motors. Because of ignoring stator flux linkage of direct torque control in constant torque region, driving of brushless DC motors is not complicated. In order to solve the problems associated with conventional PI speed controller, a new speed control based on adaptive-neuro fuzzy inference system is proposed to eliminate overshoot in the torque and speed responses, simplify designing and reduce complexity of math formulas. To reduce rising time, PD controller is used with adaptive-neuro-based Fuzzy Inference System. The effectiveness of proposed system has been validated by simulation results.","PeriodicalId":101507,"journal":{"name":"2011 International Conference on Electrical Machines and Systems","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125211738","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}

Two machines have equal tooth widths, with one having a coil wound on every tooth and the other having a coil wound on alternate teeth, while the third machine has also coils wound on alternate teeth but these are wider than the unwound teeth.
