【Note】
(*1)In case you use with 24V, please contact us since peak torque would change.
(*2) Please ask us if there is a speed you prefer.
(*3) Rated armature current is the value measured with the standard heat sink attached to the motor at an ambient temperature of 40°C.
(*4) Please ask us if there is a particular resolution you prefer.
The maximum rotational speed is limited by the encoder response frequency, and the speed range can be increased further by reducing the encoder resolution.
