The principle of the operation of the step petalousmicromotors based on the effect of the electrostatic rolling on theferroelectric surface is considered. These micromotors producedby means of microelectronic technology are distinguished as beingenergy-intensive (more than 1 J/m~2 at 20-40 V vol.tage) and theyprovide precise movement: the step ranges from 10 A to 100#mu#m. The technical and experimental data are givencharacterizing the energetic and mechanical parameters of these micromotors.
