Abstract: A radial field electrostatic micromotor produced by photolithographic micromanufacture includes a stator provided with several groups of electrodes angularly offset from one another about an axis of rotation of the micromotor, an electrically conducting rotor at least one arm of which has a counter electrode adapted to cooperate with the stator electrodes to form an air gap therebetween, and a guide ring adapted to drive the rotor in rotation and possibly in translation. The micromotor has a rotor comprising at least one bridging element arranged at least partly above an electrostatic field plane (PCE) of the micromotor. The bridging element constitutes an elevated arm of the rotor having one or more mechanically or electricity functional members adapted to cooperate with one or more complementary members located in or outside the electrostatic field plane and inside or outside the group of stator electrodes.
