Muzzle velocities in excess of 2km/s are achievable by rail guns and this provides ranges far in excess of current capability. In addition this speed allows the kinetic energy of around 60 MJ alone to provide the destructive effect. The absence of high energy explosive in the warhead also simplifies ship design by the removal of the need for magazines. However such performance requires, for a 20 kg projectile, very large amounts of stored electrical power, perhaps in excess of 200 MJ, together with an allocation of up to 20 MW steady power generation to sustain a firing rate of 6 rounds per minute. A previous paper used a co-energy analysis to explore the ship integration issues such as heat management and rail stresses arising from the operation of a rail gun. This paper extends the granularity of the physical simulation of the rail gun's operation by using a finite element approach based on Ampere's law of magnetic induction and compares its results to those of the original co-energy analysis.","PeriodicalId":446953,"journal":{"name":"2009 IEEE Electric Ship Technologies Symposium","volume":"160 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114610560","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}

To achieve high torque density and power factor, increasing the saliency ratio Ld/Lq and making the difference of these inductances (Ld-Lq) large enough are well known methods. Otherwise, the performance of the motor will remain below that of a similar induction machine using similar stator. By placing a proper amount of permanent magnets inside of the rotor in proper position it will be possible to achieve a significant improvement in performance of this permanent magnet assisted SynRM (PMa-SynRM) which will be comparable with induction machines with same stators. This PMa-SynRM will have benefit of reduced price due to use of conventional induction machines stators. This study investigates the characteristic of an optimized PMa-SynRM rotor for a specific 36-slot NEMA-Frame stator used in 7.5 HP induction motor and the paper presents the comparison results between the PMa-SynRM, SynRM, and the induction motor obtained from FEM analysis.","PeriodicalId":446953,"journal":{"name":"2009 IEEE Electric Ship Technologies Symposium","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125238980","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}

The principal nonlinear model being used was derived in the previous works without any simplifying assumptions and can be used for any type of studies. Applying state space averaging approach to the non-linear model, dc and small-signal ac models of the high-speed FESS were derived. In this paper, these models are used to evaluate the performance of the FESS in both dc and small-signal ac modes of operations. For dc analysis, the FESS is charged from low speed to high speed and is discharged and the performance of the FESS is evaluated over complete operating range. Then, the small-signal models are developed at these dc operating points and the small-signal ac analysis is performed. This comprehensive investigation will provide a valuable database for control engineers to make an informed decision on both type and design of the controller. At the end, as a proof of the accuracy of the model, the analytical results are compared with simulation results using PSIM package.","PeriodicalId":446953,"journal":{"name":"2009 IEEE Electric Ship Technologies Symposium","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124563766","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}
