Abstract
A magnetic encoder system (2) of a sewing machine drive comprises a disk (5), which is magnetized, an incremental track (8) and a reference track (9). The incremental track (8) extends completely around the disk (5) and has alternating pole elements (10), which serve as incremental markings. The reference track (9) is designed as a ring-shaped section on the disk (5) and has a monopole (11). The result is a magnetic encoder system (2), for example for a servo motor of a sewing machine.
