Abstract

Un rotor comprende laminaciones con una pluralidad de ranuras de barras de rotor con un arreglo asimétrico alrededor del rotor. Las laminaciones también tienen las ranuras de imán separadas a la misma distancia angular alrededor del rotor. Las ranuras de imán se extienden junto al diámetro exterior de rotor y tienen imanes permanentes situados en el mismo que crean polos magnéticos. Las ranuras de imán podrían ser formadas más largas que los imanes permanentes situados en las mismas y definen una o más aperturas de ranura de imán. Los imanes permanentes definen un número de polos y un paso polar. Las ranuras de barra de rotor son separadas de las ranuras adyacentes de imán por una distancia que es al menos del 4% del paso polar. El material conductivo es situado en las ranuras de barra de rotor, y en algunas modalidades, podría ser situado en las aperturas de ranura de imán.
