Sigma-5 Direct Drives

Sigma-5 Direct Drives

With a full product lineup, YASKAWA has the answer that can meet your needs for compact drive systems with high torque and high accuracy.

  • High torque and High speed
    High-torque operations are realized without gears with an instantaneous peak torque of 6 Nm to 600 Nm. High-speed operations reduce the cycle time. (Maximum motor speed : 250 / min to 500 / min)
  • High precision
    High-precision indexing of 1,000,000 pulses per rotation (P/R) is available. High-resolution encoder(20-bit):1,048,576P/R
    No backlash results in high-precision, high-speed operation with short settling times.
    High accuracy in torque control is enabled by current control algorithms with conversions for the d-q axis.
  • Compact
    The size of the drive section in the machine is reduced because of the motor design.
    Less space is required for installation because hollow space in the motor can be used for wiring and piping.
  • Easy
    Smooth and noiseless drive
    Use of a serial encoder reduces the amount of wiring.
    The gearless drive requires no maintenance for lubrication or any inspections for wear and tear.
    Speed, torque or positioning control is enabled via parameters changes.
