  1. Contact your local sales office if the load to motor inertia ratio exceeds the value in the table.
  2. The shaft-through portion is excluded.
  3. The value in brackets is applicable when the torque is increased with a combination with a larger-capacity servo amplifier.
  4. The continuous running duty and the speed are not guaranteed when the power supply voltage is dropped.
  5. When unbalanced torque is generated, such as in a vertical lift machine, keep the unbalanced torque of the machine under 70 % of the servo motor rated torque.
  6. For the HK-KT053W with an oil seal, use 80 % of the rated output.
  7. When IP67 cables are required, please contact Mitsubishi Electric System & Service Co., Ltd. OVERSEAS SERVICE SECTION. (Email: osb.webmaster@ melsc.jp)
  8. 28 times or less for 6000 r/min or less.
  9. When the servo motor is combined with a 100 W servo amplifier, the recommended load to motor inertia ratio is for operating the servo motor at the rated speed.If operating the servo motor at a speed exceeding the rated speed, check the need for a regenerative option with the drive system sizing software Motorizer. A servo amplifier with a larger capacity can be combined.

  1. Contact your local sales office if the load to motor inertia ratio exceeds the value in the table.
  2. The shaft-through portion is excluded.
  3. The value in brackets is applicable when the torque is increased with a combination with a larger-capacity servo amplifier.
  4. The continuous running duty and the speed are not guaranteed when the power supply voltage is dropped.
  5. When unbalanced torque is generated, such as in a vertical lift machine, keep the unbalanced torque of the machine under 70 % of the servo motor rated torque.

  8. 28 times or less for 6000 r/min or less.
  9. When the servo motor is combined with a 100 W servo amplifier, the recommended load to motor inertia ratio is for operating the servo motor at the rated speed.If operating the servo motor at a speed exceeding the rated speed, check the need for a regenerative option with the drive system sizing software Motorizer. A servo amplifier with a larger capacity can be combined.
