Wpływ osadzenia magnesu na parametry silnika magnetoelektrycznego o rozruchu bezpośrednim

The paper deals with the influence of magnet air gap on parameters of Line Start Permanent Magnet Synchronous Motor. To examine this phenomena time stepping finite element model was built. Three models with different magnet's air duct are considerated. There are shown calculation results such as flux density distribution and back EMF waveform at no load. It is noticed that magnet air duct causes back EMF decrease up to 13%. Moreover it also leads to lower power factor and higher no load line current.
