SGLG Series
Iron-less coil and magnet track components
Coreless GW linear servo motors are composed of moving coils and stationary magnet tracks. The moving coil has no iron content and is made of accurately resin molded motor windings. The stationary magnet track is made of two nickelized steel plates with accurately placed rare-earth magnets on each side. The steel plates are jointed at one end to form a U-channel to provide space for the moving coils.
SGLG Series Features Highlights:
- Achieve smooth linear motion with an ironless design that eliminates motor cogging.
- 200 V windings
- 40 to 3000 N of peak force
- Standard and high force magnetic ways
- Zero cogging for minimal force ripple
