1. 21. High Precision Positioning and Very Low Velocity Control of a Permanent Magnet Synchronous Motor

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Carl-Hampus Isaksson; Patrik Önnheim; [2015]
   Keywords : Technology and Engineering;

   Abstract : The purpose of this report is to evaluate a direct driven permanent magnet motor in high accuracy position and low speed operation. Actuation in this case is usually accomplished by stepping motors combined with belts and pulleys. High accuracy positioning is considered to be within 0.1 degrees and low speed 0. READ MORE

   Abstract : The aim of this master thesis is to design and analyse a FSCW PMaSynRM (Permanent Magnet assisted Synchronous Reluctance Motor) for industrial applications. The design process includes analytical calculations (initial design and PM amount minimization) and nite element method (FEM) based design optimization. READ MORE

4. 23. 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

   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

6. 25. Electric Motors for Vehicle Propulsion

   University essay from Fordonssystem; Tekniska högskolan

   Author : Martin Larsson; [2014]
   Keywords : electric motor; vehicle propulsion; efficiency map; DC; induction; permanent magnet; switched reluctance;

   Abstract : This work is intended to contribute with knowledge to the area of electic motorsfor propulsion in the vehicle industry. This is done by first studying the differentelectric motors available, the motors suitable for vehicle propulsion are then dividedinto four different types to be studied separately. READ MORE
