Motor Shaft Rotation Speed versus Internal Resistance Torque
Note 3) Internal resistance torque increases in low-temperature environments (10°C and below).
Therefore, it is recommended to use a higher safety margin when selecting a product.

Note 4) Please select and use a motor that is suited to the usage conditions. The table
shows only a portion of the model numbers for motors. For details regarding model
numbers, please see the catalog for each respective motor manufacturer.
Note 5) If the maximum torque of the installed motor will exceed the permissible input
torque (p. 13), please consider a safety measure to limit the torque.
Note 6) Please select a D-cut type motor output shaft.
Note 7) Installation may not be possible depending on the motor options, so please verify in
advance.
