Abstract
In an electrostatic micromotor, a mobile substrate faces a fixed substrate and is suspended over the fixed substrate at a given distance of separation in an operative resting condition; an actuation unit is configured so as to give rise to a relative movement of the mobile substrate with respect to the fixed substrate in a direction of movement during an operative condition of actuation. The actuation unit is also configured so as to bring the mobile substrate and the fixed substrate substantially into contact and to keep them in contact during the operative condition of actuation. The electrostatic micromotor is provided with an electronic unit for reducing friction, configured so as to reduce a friction generated by the contact between the rotor substrate and the stator substrate during the relative movement.
