KDU

The KDU Series are Direct Drive Motors which achieve 10 arc-sec positioning accuracy as well as ±0.5 arc-sec repeatability with a resolution of 0.16 arc-sec. The KDU has a large Hollow Shaft design which allows cables, shafts or lasers to pass through the axis of rotation.

Key Features:

Exceptional positional accuracy
Exceptional repeatability
Ultra high resolution

Note1: * The table above shows output values of output shaft. Note2: * The values in the table above are obtained when connected to HA-770 servo driver. Note3: * The repeatability positioning precision and Absolute positioning accuracy repeatability are the values measured in an environment of 23 ±0.3°C in temperature, 50% RH in humidity and with output shaft facing upward in mounting direction. Please contact Harmonic Drive LLC, for specific environmental tolerances. Note4: * Value after angular position of the HA-770 servo driver is corrected.
