Abstract
We have developed the liquid crystalline micromotor driven by the backflow which is the liquid crystalline flow induced by an electric field. The liquid crystalline motors have simple structure composed of an outer cylinder, a rotary shaft and a liquid crystalline material which is filled between the cylinder and the shaft. The shaft of the motor rotates when the pulsed voltage is imposed on the liquid crystal. The rotation speed strongly depends on the voltage and the frequency of the pulse. The rotation speed increases with the increase of the voltage, and becomes almost constant for the voltage higher than 7V. It is also found that the rotation speed becomes maximum the frequency 400Hz.
