Sigma-7 Servo Products


Match any Yaskawa servo motor with a fully digital, easily networked SERVOPACK amplifier. The productivity features within each SERVOPACK enable more precise control and shorter settling times. Each model is equipped with a package of software algorithms that tune automatically, suppress vibration, and compensate for friction and ripple and effects. Choose from single or dual axis designs.

Rotary Servo Motors

In terms of compact size, high resolution and precise performance, the automation industry has never seen a line of rotary servo motors like today’s Sigma-7. The full range of products from 3w to 55kw perform in higher temperature extremes, at higher altitudes and in more washdown environments than ever before. Every Sigma-7 model is backward compatible with existing Sigma-5 and Sigma II products.

  • SGM7J 50W - 750W (200V), 200W - 1.5kW (400V)
  • SGM7A 50W - 7kW (200V), 200W - 1kW (400V)

Gear Motors

Gear down a motor's output to suit the mechanical requirements of a machine with our line of gearmotors, custom built for the physical size and operating requirements of each Yaskawa servo motor.

Direct Drive Servo Motors

Smooth rotary motion is the hallmark of the SGMCS servo motor, which features a direct drive design in which a load is directly attached to the motor surface.

Linear Servo Motors

Yaskawa linear servo motors replace the backlash, friction, inertia and wear of mechanical linkages with smooth, precise, high performance linear motion in a compact footprint.

  • SGLF2 Series Second generation iron-core coil and magnet track components
  • SGLF Series Iron-core coil and magnet track components
  • SGLT Series Balanced Iron-core coil and magnet track components

Linear Slides

The Sigma Trac slide includes direct drive components, carriage, bearings, base, and linear encoder all integrated into a plug-and-play package.

  • Sigma Trac II Ready to run linear stage solution featuring the latest linear motors
