Abstract
An electrostatic motor comprising a stator and a rotor, one of which is equipped with a plurality of lands to which a voltage is sequentially applied. The other of the stator and rotor is made of conductive material. Rolling contact is established between the stator and rotor along at least one line of contact. The rolling contact is controlled to repetitive first and second paths along first and second surfaces of the stator and rotor, respectively, in which the lengths of the first and second paths are different. Embodiments include a cylindrical motor, a flexible disk motor and a conical motor.
