Abstract
We have presented the first direct observation of electric field induced rotation of epoxy based polymer rotors. Polymer disks and gears were prepared in few micrometer dimensions as rotors. Electrorotation of these sub-millimeter sized tools was studied under uniform DC electric field. The rotational speed of micron-sized polymer rotors can be conveniently tuned in wide range (between 300 – 3000 rpm) by the DC electric field intensity, opening new perspectives for their use in micro electric motor applications.

Summary
All neutral materials experience forces and torques when subjected to high electric field. These interactions can be utilized in several mechanisms from electrostatic spraying to electrospinning. Discovery of electrorotation phenomena has initiated us to the construction of novel polymer based micro sized motors with tunable angular frequency [1]. We have reported the development of micron-sized polymer composites disks that showed electrorotation in uniform DC electric field [8,9,10,11]. We report that a novel polymer has been used for realization of a rotor part of side drive micromotor, based on the electrorotation phenomena [1]
