Abstract
"MáQUINA ELéTRICA GIRATóRIA". A máquina elétrica giratória compreende pelo menos um ventilador (43) provido de pás que deixam entre elas canais de ventilação (48) que divergem e que são adaptadas para gerar um fluxo de fluido de resfriamento através da máquina; o ângulo de incidência (B) das pás, ao nível da borda de ataque está compreendido entre 150<198> e 175<198>, enquanto que o ângulo de incidência (A) das pás, ao nível da borda de fuga, está compreendido entre 90<198> e 165<198> em relação à tangente a um círculo (C) gerado por ocasião da rotação das pás; a relação entre o passo médio das pás (46) e o comprimento médio dessas últimas é inferior a 0,975. Aplicação nos ventiladores para alternador de veículo automóvel.
