Thesis deals with random wound stator - conductors’ distribution in stator slot and its influence on proximity effect (non-uniformity of current distribution) in conductors near air gap. Also circulating currents between parallel strands of winding are assumed, same as influence of rotor permanent magnets magnetic field. Conductor level thermal simulation is conducted according to used insulation system of machine and current distribution. Chapter 1 – 3 deals with theory, subchapter 4.3 investigates thermal properties of used materials for thermal simulations and chapters 4 and 5 presents work itself – simulation of given machine (current distribution in conductors) in Ansys Maxwell and thermal simulation in FEMM and Ansys 16.0.
