Abstract

La máquina eléctrica de CA, sin escobilla, multifásica comprende un batidor de estator con una superficie provista de ranuras paralelas yproyecciones dispuestas alternativamente, siendo cada una de las aberturas sustancialmente tanancha como el ancho máximo de la ranura correspondiente, yun marco de rotor con una superficie provista con medios magnéticos permanentes con secciones de superficie respectivas que se encuentran frente a las ranurasy proyecciones. Todas lassecciones de la superficie de los medios magnéticos producen una densidad de flujo magnético con un componente de amplitud promedioBr(O) perpendicular a la superficie correspondiente del estator, que está sustancialmente definida por laecuación (I), dond e La(O) está definida por laecuación (II), donde O es un ángulo de posición en radianes con respecto a una posición de referencia en el bastidor del rotor, Br(O) es el componente deamplitud promedio en el ángulo de posición O;Lv(O) es un intervalo entre las proyecciones y la superficie del bastidor del rotor en el ángulo de posición(O); Mr(O) es un componente de inducción residual del medio magnético en el ángulo de posición (O), siendo Mr(O) perpendicular a lasuperficiecorrespondiente del estator, siendo Mr(O) alternativo con un período correspondiente a 4/K; K es un número par representativo de todas lassecciones de superficie; y C es una constante arbitraria. La presente invención también serefiere a un método para o perar la máquina eléctrica de CA, sinescobilla multifásica.
