Our industry-leading, high-speed industrial robots include high-payload, extended-reach, ultra-maneuverable seven-axis and unique 15-axis dual-arm robots.
Sigma-X Servodrives
Our Sigma-X series offers a whole range of innovations and the entire experience of many generations of servo drives. You will notice this right from the commissioning stage.
Yaskawa equips the servo packs with functionalities that reduce the time required for commissioning to a minimum. The Sigma series delivers outstanding performance and masters the many challenges found in a modern automated machine: Shortest positioning times, highest synchronization quality, compensation of friction, suppression of various (resonance) frequencies and much more.
Sigma-X Servopacks
With real-time data collection, speeds up to 7000 RPM, frequency response of 3.5 kHz, and multi-axis amplifiers with expanded functions to improve precision, Sigma-X takes servo response to a higher level to maximize your machine performance. Sigma-X Servopacks are EtherCATcompatible to communicate seamlessly with our iCube Control platform. They are available in power ranges from 50 W to 15 kW.
Unleash the full power
For a servo system to deliver the fastest, smoothest and most precise motion possible, unwanted mechanical effects that occur in every machine must be compensated for. The sophisticated suppression functions of Yaskawa servopacks reduce these negative influences to a minimum.
Machine vibrations are eliminated by Yaskawa Vibration Suppression, which samples your equipment’s natural oscillations and uses compensating frequencies to cancel them out.
Ripple compensation suppresses so-called cogging torque effects, which can occur at low motor speeds. This achieves outstanding speed stability.
Our servo amplifiers offer several adjustable filters to effectively counteract resonances that occur in the machine mechanics.
The Friction Compensation function enables smooth starting at all times, even if there is high static friction.
The servo amplifier offers the option of electronically defining up to nine frequencies (from a few Hz to several kHz) to counteract vibrations and resonances in the mechanics.
Sigma series servo motors
More power per engine volume
- Thanks to a segmented stator core design and highly automated winding layout, a significantly higher packing density is achieved than with other manufacturers. This results in a significantly higher power density per unit volume.
- Encapsulated windings prevent shorts between windings, improving heat dissipation
- Increased precision during production minimizes the air gap between the rotor and stator. The improved magnetic flux density achieves a higher torque with reduced cogging at the same time.
- By reducing the space taken up by the end turns of the winding, overall motor length is significantly reduced
- Neodymium-Iron-Boron rotor magnets optimize flux density in the motor
Batteryless absolute encoder
- Simplifies wiring in control panels
- Rotation data are retained
- No need to stock batteries
Increased speeds
The maximum rotation speed of the newest generation Sigma motors has increased from the earlier value of 6,000 RPM to 7,000 RPM.
Improving maximum servo motor rotation speed can reduce positioning time, which can contribute to higher productivity.
High resolution 26-bit encoder
The resolution of the encoder has been increased to 26 bits, four times that of the previous generation.
- Increased positioning resolution/stop precision = Precise stops
- Decrease in speed ripples = Smooth movement and improved machining precision
