【Postscript】
The maximum rotational speed is limited by the encoder's response frequency, but the speed range can be further increased by reducing the encoder resolution.

【Note】
(※1) In case you use with 24V, please contact us since peak torque would change.
(※2) Please ask if there is a speed you prefer.
(※3) Rated armature current is the value measured with the standard heat sink attaxhed to the motor at an ambient temperature of 40℃ .
(※4) Please ask if there is a particular resolution you prefer.
