1. 6. Design of a Synchronous Reluctance Motor Assisted with Permanent Magnets for Pump Applications

   University essay from KTH/Elektrisk energiomvandling

   Author : Adrian Ortega Dulanto; [2015]
   Keywords : Demagnetization study; efficiency; FEM; parametric study; Permanent-Magnet Assisted Synchronous Reluctance Motor; prototype;

   Abstract : This Master thesis focuses on the design of a high efficiency Permanent-Magnet-Assisted Synchronous Reluctance Motor (PMASynRM) intended for pump applications. The new motor is designed to replace an existing Induction Motor (IM) in a pump product. The basic principles of SynRM, and PMASynRM Motors and a good analytical model were introduced. READ MORE

3. 7. Design and Analysis of a Fractional-Slot Concentrated-Wound Permanent-Magnet-Assisted Synchronous Reluctance Machine

   University essay from KTH/Elektrisk energiomvandling

   Author : Celia Carvajal Almendros; [2015]
   Keywords : Demagnetization; finite element method; flux-weakening; fractional slot concentrated winding; overload capability; permanent magnet assisted synchronous reluctance machine; torque ripple; Avmagnetisering; finita elementmetoden; fältförsvagning; koncentrerade lindningar; momentrippel; permanentmagnetassisterad synkron reluktansmaskin; överbelastningskapacitet;

   Abstract : The growing need for simpler and cheaper manufacturing process has led to the research into fractional-slot concentrated-wound (FSCW) motors. This concept has been widely investigated for surface-mounted permanent magnet (SMPM) machines. This thesis studies the same concept applied for synchronous reluctance machines (SynRM). READ MORE

4. 8. Design of a Ferrite Permanent Magnet Rotor for a Wind Power Generator

   University essay from Elektricitetslära

   Author : Petter Eklund; [2013]
   Keywords : generator design; ferrite permanent magnets; wind power;

   Abstract : Due to the insecurity of the supply of raw materials needed for neodymium-iron-boron magnets, typically used in permanent magnet generators, the use of ferrite magnets as an alternative was investigated. The investigation was conducted by attempting to redesign a generator that previously used neodymium-iron-boron magnets for use with ferrite magnets. READ MORE

5. 9. Optimization of Line Start Permanent Magnet Synchronous Motor for Magnet Cost Reduction

   University essay from KTH/Elektrisk energiomvandling

   Author : Amit Kumar Jha; [2012]
   Keywords : Line start reluctance motor; LSPM; magnet assisted reluctance motor; Magnet volume reduction; Optimization of LSPM;

   Abstract : In this thesis different methods of optimizing line start permanent magnet motor (LSPM) for magnet cost reduction is studied. Influence of different parameters has been studied by simulating magneto-static and transient FEM models of the machine. Finally a motor design of a LSPM with high rotor saliency has been proposed.
