    摘要: A display module has a two-phase motor comprising a rotor (6) having N pairs of poles magnetised radially, in alternate directions, N being equal to 3 or 5, and a stator part (4) having at least two W-shaped circuits made from radial pole teeth extending inwards from a peripheral closed belt and having a coil (5) on a central leg of the W, said W-shaped circuits being arranged in such a way that when the central tooth of one of the W-shaped circuits is positioned facing a rotor magnetic transition, at least one central tooth of another W-shaped circuit is positioned facing a rotor magnetic pole. Said display module additionally comprises at least one means of specific mechanical interaction (13) between the rotor and the stator, providing angular friction at a force that is substantially constant depending on the speed of the rotor (6) relative to the stator (4), and at a value lower than the torque produced by the electromagnetic interaction between the rotor and the stator.

    摘要: The invention relates in particular to a method for parameterizing a system for measuring an absolute position, said system comprising a permanent magnet, at least one probe that is mobile relative to said magnet over a given path, and a calculation means providing position information calculated on the basis of the arctangent of the ratio, to which a correction coefficient G is assigned, between the output signals of the probe, wherein said signals are pseudo-sinusoidal and squared. Said method includes an optimization operation that involves selecting the value of the coefficient G that minimizes the errors of the measurement system resulting from the pseudo-sinusoidal character of the signals output from the probe.
