在对介电流体施加高电场时，引起流体的对流运动。通过控制流体在非均匀直流电场中的运动，研制了一种新型的流体马达。对于转子半径为10 mm的电动机，在5 kV的直流电压下可以实现大于15 s−1（150 rpm）的角速度。电能到动能的能量转换效率约为4%。由于不需要磁场和开关电路，流体马达的优点将通过尺寸减小而增强。介电流体马达作为微机械中的机械能源是有吸引力的。
On the application of high electric fields to a dielectric fluid, a convective motion of the fluid is induced. By controlling the fluid motion in nonuniform dc fields, a new type of fluid motor is developed. An angular velocity of more than 15 s−1 (150 rpm) can be achieved at a dc voltage of 5 kV for a motor with a rotor radius of 10 mm. The efficiency of energy transformation from electric to kinetic energy is about 4%. Since magnetic fields and switching circuits are not required, the advantage of the fluid motor will be enhanced by size reduction. The dielectric fluid motor is attractive as a source of mechanical energy in a micromachine.
