HR4 Motor from Nanomotion

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.
