  • Sewing Machine Drive
    Publication number: 20200270789
    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.

  • Sewing Machine Drive
    Publication number: 20170183800
    Abstract: A magnetic encoder system of a sewing machine drive comprises a magnetic, magnetised disc with alternating north and south pole elements, which are used as incremental markings. The latter are designed as a full ring-incremental track, which extends around a circumference of the ferritic disc, and as an annular section incremental track, which is designed as an annular section on the ferritic disc. The result is a magnetic encoder system for a servomotor of a sewing machine.

  • Control equipment for an industrial sewing machine
    Patent number: 7062349
    Abstract: In a control equipment for an industrial sewing machine, it being possible, via switchgears such as switches, probes, sensors or the like, to switch on or off functions and connection states, by a certain voltage level being applied to an input circuit of the control, the input circuit generating an output signal, it is provided that upon the application of varying input voltages Ue, the output voltages Ua generated are the same in each case.
