For the SynRM, a universal analytical model is proposed based on Maxwell\u0026rsquo;s equations and conformal mapping. Saturation effect is modeled with the help of the magnetic equivalent circuit (MEC) model. For the single-phase IM, the equivalent circuit model is adopted in order to analyze the machine performance from the design parameters.\u0026nbsp;Evolutionary algorithms are used to conduct the multi-objective optimization (MOO) for the SynRM and single-phase IM. The optimal designs show improved performance compared with the original designs, and the time consumed is acceptable due to the time efficiency of the analytical model.\u0026nbsp;The ultimate goal of this research is to create a computationally efficient design tool that has the ability to rapidly locate an optimal design candidate which satisfies the design specifications and objectives.\u0026nbsp;Once the optimal design candidate is located, a final design can be easily completed by further refinement using the commercially available finite element analysis (FEA) software.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Electro-magnetic Modeling and Design Optimization of Synchronous Reluctance Machines and Single-phase Induction Motors"}],"uid":"30864","created_gmt":"2019-07-23 20:13:07","changed_gmt":"2019-07-23 20:36:32","author":"Tasha Torrence","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2019-07-29T12:30:00-04:00","event_time_end":"2019-07-29T14:30:00-04:00","event_time_end_last":"2019-07-29T14:30:00-04:00","gmt_time_start":"2019-07-29 16:30:00","gmt_time_end":"2019-07-29 18:30:00","gmt_time_end_last":"2019-07-29 18:30:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"434381","name":"ECE Ph.D. Dissertation Defenses"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"},{"id":"1808","name":"graduate students"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
