Abstract:
A method of determining a position on a magnetic track of an encoder includes providing a group of magnetic pole pairs that forms a portion of the magnetic track, recording a relative position within a first magnetic pole pair in the group using a first magnetic sensor proximate a high-resolution portion of the magnetic track, detecting adjacent pole junctions within the group of magnetic pole pairs with a second magnetic sensor positioned proximate a reference portion of the magnetic track, correlating the adjacent pole junctions with the first magnetic pole pair to determine a relative position of the first magnetic pole pair within the group, and calculating a local absolute position within the group using the relative position within the first magnetic pole pair and the relative position of the first magnetic pole pair within the group.
