Abstract

"MáQUINA ELéTRICA QUE POSSUI UM ESTATOR E UM ROTOR, E, ALTERNADOR OU ALTERNADOR-MOTOR DE ARRANQUE DE VEìCULO AUTOMóVEL". Máquina elétrica que possui um estator (1) e um rotor (2), o estator possuindo pelo menos uma bobina de induzido (14) alojada em pelo menos um par de entalhes (13), o rotor possuindo pelo menos dois ímãs de excitação sucessivos que no rotor geram dois fluxos magnéticos que têm, tangencialmente ao longo da estrutura de rotor, componentes de sentidos opostos, o dito rotor apresentando entre esses dois ímãs um número de entalhes par que definem entre si pólos salientes e nos quais são recebidos cordões de bobina(s) que são próprios para ser alimentados para definir com os ímãs pólos alternados, caracterizado pelo fato de que cada um dos entalhes (23) que recebem os cordões de bobina(s) (26) só é ocupado por um único cordão ou vários cordões bobinados em volta de um mesmo pólo saliente e pelo fato de que a árvore (A) do rotor é feita de um material magnético, a dita máquina possuindo próximo da dita árvore (A) e dos ímãs (27) pelo menos uma zona não magnética (28, 28a; 30) que minimiza ou suprime os fluxos de fuga na direção da árvore do rotor.
BRPI9906555-0A 1998-06-25 1999-06-25 mÁquina elÉtrica possuindo um estator e um rotor em material magnÉtico, e compreendendo pelo menos uma zona nço magnÉtica que reduz ou suprime fugas. BR9906555B1 (pt)
