Abstract
abstract of the disclosure rotor for a line start permanent magnet machine a rotor comprises laminations with a plurality of rotor bar slots with an asymmetric arrangement about the rotor. the laminations also have magnet slots equiangularly spaced about the rotor. the magnet slots extend near to the rotor outer diameter and have permanent magnets disposed therein creating magnetic poles. the magnet slots may be formed longer than the permanent magnets disposed therein and define one or more magnet slot apertures. the permanent magnets define a number of poles and a pole pitch. the rotor bar slots are spaced from adjacent magnet slots by a distance that is at least 4% of the pole pitch. conductive material is disposed in the rotor bar slots, and in some embodiments, may be disposed in the magnet slot apertures. __________________________________________________ tradução resumo patente de invenção: "rotor para uma máquina de ímã permanente de partida em linha". a presente invenção refere-se a um rotor que compreende laminações com uma pluralidade de fendas da barra do rotor com uma disposição assimétrica ao redor do rotor. as laminações também têm fendas do ímã equiangulamente espaçadas ao redor do rotor. as fendas do ímã se estendem perto do diâmetro externo do rotor e têm ímãs permanentes dispostos nelas criando polos magnéticos. as fendas do ímã podem ser formadas mais longas do que os ímãs permanentes dispostos nelas e definem uma ou mais aberturas da fenda do ímã. os ímãs permanentes definem inúmeros polos e um passo polar. as fendas da barra do rotor são espaçadas a partir de fendas do ímã adjacentes por uma distância que é pelo menos 4% do passo polar. o material condutor é disposto nas fendas da barra do rotor, e, em algumas modalidades, pode ser disposto nas aberturas da fenda do ímã.
