<p>The invention relates to a limited displacement motor, meant to drive a system of solar orientation of photovoltaic cell panels. According to the invention, the electric motor comprises some in-line driving modules (A, B, C, D and E) placed on two guiding rods (1 and 2) so that they can slide, acting upon one another, by some driving rods (3a, 3b, 3c, 3d and 3e) put into motion by some electromagnetic paraffin actuators (4a, 4b, 4c, 4d and 4e) and determining the displacement of a slide (5) which slides along the two guiding rods (1 and 2) and is integral with a driving rod (6), which during the pause periods presses on the actuators (4a, 4b, 4c, 4d and 4e), by means of a spring (7), causing the return thereof to the initial position.</p> |
