Temperature Correction Factor

Please modify rated/max. torque value with the below temperature correction factor when it’s higher than 30ºC.

Ambient Temperature Correction Factor

30 ℃ ~ 40 ℃ 0.8
40 ℃ ~ 60 ℃ 0.7
60 ℃ ~ 120 ℃ 0.55
Higher Efficiency through Higher Gain Allowance
Icon design for the contents of the list below
  1. Higher Gain Value
  2. Higher Responsivity & Suppressing hunting and resonance
  3. Higher Work Efficiency
  • Gain value is an indicator that shows how accurately it operates according to the command on servo motors.
  • Higher gain brings higher responsivity, at the same time it also results in hunting and resonance onto application.
  • The anti-vibration rubber (HNBR) is excellent for damping and has higher dynamic stiffness, so it enables to reduce side-effects under the increased gain value.

When SHR series is used, the gain value can be increased higher than SD series (Disk type) as there is relatively bigger gain margin on Bode Plot -180deg.

SHR series has the excellent function of damping so it allows to minimize stabilization time of the application.
