Abstract

"MáQUINA ELéTRICA ROTATIVA". Uma máquina elétrica rotativa compreende um estator (10) equipado com bobinas de induzido (18) e um rotor (20) montado rotativo no interior do estator, o rotor possuindo uma parte de rotor (210) com imãs(s) permanente(s) e uma parte de rotor com relutância (220). De acordo com a invenção o rotor é sensivelmente uniforme em sua extensão axial e possui de acordo com sua direção tangencial uma repartição de partes polares (212, 214a, 214b) com imã(s) permanente(s) (214a, 214b) que definem cada uma delas dois pólos (PSA, PNA) de polaridades impostas por imã(s), e de partes polares com relutância (222) que definem cada uma delas dois pólos (PR1, PR2) de polaridades livres. Aplicação notadamente aos alternadores e alternadores-motores de arranque de veículos automóveis.
