7. 5. Electromagnetic Energy Converters - Rotating Motors and Linear Generators

   Author : Boel Ekergård; Uppsala universitet; []
   Keywords : ;

   Abstract : This licentiate thesis presents a study of the electromagnetic properties of linear synchronous permanent magnet generators, utilized in wave energy converters, and a two pole permanent magnet motor for an electrical vehicle. Both machine topologies are presented, designed with a numerical simulation tool, based on a model derived from Maxwell’s equations. READ MORE
