Abstract

Un detector 10 de rotacion para un motor 20 de corriente directa de imán permanente miniatura que comprende una bobina 11 de induccion enrollada alrededor de un anillo 15 de flujo para el motor. El anillo 15 de flujo tiene una porcion 18 escalonada que acomoda los enrollamientos de la bobina 11. La bobina 11 produce señales eléctricas en respuesta a los cambios en el campo magnético del estator, ocasionados por la rotacion del rotor.
