The
HR4 motors are high
precision ceramic motors. The motors combine unlimited
stroke with high
resolution in compact dimensions.
Among its applications are microscopy, precision motion,
robotics, etc.
The motors provide a linear response to the input voltage. The
operation of the motor and driver resembles that of a DC-motor
driven by a
voltage amplifier. The HR4-V and HR4-U motors are constructed of materials that
have been
selected and designed for high vacuum
compatibility.
