Abstract

A presente invenção refere-se a uma lâmina de estator (10) para um motor elétrico que compreende um furo central (20), uma pluralidade de ranhuras (30) espaçadas ao redor do furo (20), e uma pluralidade de dentes (50) formados entre duas ranhuras (30) consecutivas. Os cantos (35a, 35b, 35c, 35d) formados entre as bordas da ranhura (30e e 30a, 30e e 30b, 30b e 30d, e 30c e 30a) sendo raios de arredondamento e os ângulos formados por essas bordas sendo ângulos agudos. Os dentes (50) apresentam dois flancos não paralelos (30a, 30b, 50a, 50b) que se terminam a proximidade do furo central (20) em sapatas polares (30c, 30d).
