MAGNETIC ENCODER WITH AN INDEX PULSE

Magnetic poles are regularly spaced along a path to form a magnetic track. Some of the magnetic poles are separated by regular pole junctions aligned uniformly with respect to the path of the magnetic track. At least two of the magnetic poles are separated by a skewed irregular pole junction aligned...

More Information
Summary:Magnetic poles are regularly spaced along a path to form a magnetic track. Some of the magnetic poles are separated by regular pole junctions aligned uniformly with respect to the path of the magnetic track. At least two of the magnetic poles are separated by a skewed irregular pole junction aligned such that a sensor near an edge of the magnetic track will sense a wide pole and a narrow pole to allow an index signal to be produced. Des pôles magnétiques sont espacés régulièrement le long d'un trajet pour former une piste magnétique. Certains pôles magnétiques sont séparés par des jonctions de pôle régulières, alignées uniformément par rapport au trajet de la piste magnétique. Au moins deux des pôles magnétiques sont séparés par une jonction de pôle à section irrégulière en trapèze, alignée de sorte qu'un capteur situé sur un bord de la piste magnétique peut capter un pôle large et un pôle étroit permettant de produire un signal d'index.
