Abstract

Patente de Invenção: <B>"MáQUINA ELéTRICA, PARTICULARMENTE GERADOR DE BORNES DE GARRAS"<D>. A invenção propõe um gerador elétrico, com um estator (10) anular, dotado de um enrolamento, e com um rotor de bornes de garras R, que está disposto rotativamente dentro do furo do estator e contém uma bobina de excitação coaxial ao eixo de rotor, que em sua superfície periférica apresenta vários bornes de garras (22, 23) recobrindo a bobina de excitação, que se engatam em forma de dedos com espaços intermediários (31) tangenciais, em forma de ranhura. Nesses espaços intermediários encontram-se estruturas (33) em forma de favos estendidas na direção longitudinal, com secção transversal em forma de tubo, por exemplo, redonda ou hexagonal. Com uma estrutura desse tipo, a resistência da corrente pode ser mantida pequena e evitadas turbulências, os ruídos causados pelas mesmas são reduzidos.
