Note1) The moment of input shaft conversion is only gained from the reducer, so it does not include moment of inertia of the motor.
Note2) The max. input speed is 5000rpm. Usually set to 3000rpm or less.
Note3) The permissble radial load is indicated on the center of the output shaft.
Note4) All values are within the range corresponding to helical gear.

Note1) The moment of input shaft conversion is only gained from the reducer, so it does not include moment of inertia of the motor.
Note2) The permissble radial load is indicated on the center of the output shaft.
Note3) All values are within the range corresponding to helical gear.

Note1) Please inquire to us if motor model isn't standard (Matching motor list). (The flange dimension may be different if motor assension is different.)
Note2) Rotation of the output shaft is in the same direction as that of motor input.
Note3) All values are within the range corresponding to helical gear.
