1. 1. Design and Simulation of a Slotless Aircored PM Synchronous Generator

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Bakhtiyar Asef Hasnain; Ademir Hodzic; [2020]
   Keywords : Slotless; Aircored; PM; Permanent Magnet; PMSG; Permanent Magnet Synchronous Generator; SPMSG; COMSOL; FEMM; FEM; Solidworks; Fusion 360; Axial Flux Generator;

   Abstract : This thesis is a study on an unconventional slow speed direct drive permanent magnet (PM) generator. Unlike a standard permanent magnet synchronous generator (PMSG) which has the copper coils wound around iron teeth, the work in this thesis will present a generator where the copper coils are directly mounted on the stator which eliminates the slots and teeth in the generator.

3. 2. High-Frequency Voltage Distribution Modelling of a Slotless PMSM from a Machine Design Perspective

   University essay from KTH/Elkraftteknik

   Author : Patrik Brauer; [2018]
   Keywords : Windings; drives; transients; surges; steep-fronted; slotless; litz-wire; effective relative permeability; Lindningar; elektriska drivlinor; transienter; spänningspulser; litz-tråd; effektiv relativ permeabilitet;

   Abstract : The introduction of inverters utilizing wide band-gap semiconductors allow for higher switching frequency and improved machine drive energy efficiency. However, inverter switching results in fast voltage surges which cause overvoltage at the stator terminals and uneven voltage distribution in the stator winding. READ MORE
