摘要

Electric motor for controlling the elements of the motor vehicle anti in two opposite directions, such as temperature - window or the backrests nanoparticles of seats, of the type in which the speed of rotation as a function of the resisting torque is different to a direction of rotation at the other, comprising a pair of brushes b1, b2 placed between the poles of inductors p1, p2, and capable of cooperate with an armature constitutes a manifold 14 integral with a reinforcement 12 crossing by the axis of the engine and in which are formed of the notches or coils of the connection wires of a series of blades 1, 2, .. In the form of the manifold 14, characterizes in that the brushes b1, b2 are shifted by an angle determine - a with respect to the neutral line theoretical p of the armature, the angular spacing difference - is being carried out in the direction opposed to the direction of rotation r of the engine for which the force resisting the mechanism is the most high. Starting from a motor having a given torque, the invention makes it possible to reduce the blocks is the descent, which makes it possible to alleviate the device in the case of a temperature - glass, and to improve the safety of passengers back in the case of a back articulated of the seat.
