<p>The invention relates to an electric step-by-step motor, with double rotor, made on the principle "with wheel and pawl" and which is actuated by means of some paraffin electro-mechanical actuators. According to the invention, the motor consists of a propeller (A) and two paraffin electro-mechanical actuators (A1 and A2), each included in a metallic block (1 and 1'), separated by a battery (2) with Peltier elements, each of the actuators (A1 and A2) consisting of a metallic cylinder (3) filled with a quantity of paraffin (4), inside the cylinder (3) there being placed a piston (5) separated from the paraffin layer by an elastic membrane (6), which actuates upon the piston (5), transmitting the linear movement upon some pawls (7 and 7') which actuate upon some rotors (8 and 8') which are made as gear wheels, determining their displacement by a tooth, and for providing the one-way movement of the rotors (8 and 8') is also provided with some catch pawls (9 and 9'), there being also provided some opposing springs (10 and 10'), through which the pistons of the actuators (A1 and A2) are returned to the initial position.</p> |
