In this paper an alternative arrangement to conventional Lundell automotive generators is examined. This geometry is characterized by its hybrid excitation combining the high energy density of permanent magnets and the controllability of commonly used electrical excitation - thus a simple and cost-effective control of output voltage for application in on board supply systems is possible. A simulation of the alternator using the finite-element method (FEM) is performed to optimize the rotor geometry and to develop a design, ready for prototyping. The finite-element calculation of the alternator behavior and the unknown stator current, including their reaction on the entire magnetic field, requires a transient solving process taking the geometry rotation into account and which is coupled to an electric circuit. The formulation for the transient solver is given and the coupling with external circuit exemplified. The accomplished studies, simulations and geometry optimizations are presented. In a final step the calculations are compared to prototype measurements and confronted with conventional alternator geometries. The developed geometry absorbed about five percent more power but was fifteen percent lighter than compared Lundell generator.","PeriodicalId":446844,"journal":{"name":"2007 IEEE International Electric Machines & Drives Conference","volume":"122 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129485452","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}

In order to verify the validity and effectiveness of the thermal model a 10 hp machine was dismantled, physically measured and reassembled inserting thermal probes in it at different locations to test their temperatures. The model is simulated using PSPICE schematics for finding temperatures at different locations. The simulated results match with the experimental results. The model is further modified to fit a new direct lamination cooling (DLC) topology, characterized by coolant flowing through tubes inserted into the back iron and by modified dimensions to make the active cooling more effective. The flow within the tubes inserted in the back iron of a DLC motor is modeled using lumped parameter approach. The parameters are formulated from purely dimensional data and thermal constants for convection and conduction. The heat that is pulled out by the circulating liquid in the holes is modeled by adding a lumped heat sink which is represented as a current sink at the stator iron node in the model. The model is simulated for 30% and 60% cooling using PSPICE Schematics for finding temperatures at different locations. An empirical 10 hp DLC model is simulated inferring the data from AeroVironment. A comparative study between the two models shows the effectiveness in cooling technique employed.","PeriodicalId":446844,"journal":{"name":"2007 IEEE International Electric Machines & Drives Conference","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128722518","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}

Based on the analysis of the basic DTC theory, the space vector pulse width modulation (SVPWM) strategy for permanent magnet synchronous motor is designed. In the scheme, the error between the reference stator flux linkage and the estimated stator flux linkage is calculated during each sampling period, and the two nonzero adjacent voltage vectors are selected and then the operation time is calculated accurately. Finally the linear combination method is used to synthesize a new voltage vector. Compared with several fixed voltage vectors in the basic DTC, the voltage vectors in this strategy can trace the torque and the stator flux linkages very well because of their random, so the torque ripple may be reduced. This algorithm can also ensure the constant switch frequency. The simulation results show that this method is very feasible. It can dramatically reduce the torque and the stator flux linkage ripples of the basic DTC, and at the same time, the dynamic responses of the torque and the angular velocity are very fast. The control effect, thereby, is obtained very well.","PeriodicalId":446844,"journal":{"name":"2007 IEEE International Electric Machines & Drives Conference","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132416705","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}
