Abstract

La presente de invencion se refiere a un sensor angular que tiene un estator magnético al menos parcialmente blanco (104) y un rotor magnético al menos parcialmente blanco (102) opuestos entre sí y que forman entre ellos un entrehierro. La resistencia magnética en el entrehierro cambia periodicamente debido a la configuracion del rotor y varía alrededor de su circunferencia. El sensor angular tiene un transmisor de flujo magnético dispuesto en el estator y que genera una distribucion de flujo magnético pre-definida en el entrehierro por medio de al menos un par de polos. Además, un receptor de flujo magnético que mide la intensidad del flujo magnético por medio de al menos dos polos de senal desfasados entre sí un ángulo determinado, está dispuesto en el estator, con lo cual un valor angular de una posicion del rotor con respecto al estator puede ser derivada de las dos senales emitidas por el receptor. De acuerdo con la invencion, el estator (104) tiene una gran cantidad de dientes (110) distribuidos sobre su circunferencia, estando dichos dientes separados entre si por ranuras, y el transmisor de flujo magnético comprende al senos dos arrollamientos primarios dispuestos de manera tal que al menos un diente no lleva arrollamientos primarios.
