<p>The encoder (2) has north and south poles (N, S) with opposed sign polarities on the circumference of the encoder, and a junction provided between short and long poles (P, G) with opposed sign polarities, where an angular width of the pole (G) is higher than an angular width of the pole (P). The pole (G) has a same signed short stabilizing pole (Ps) placed near the pole (P) whose angular width is identical to the pole (Ps). A same signed complementary pole (Pc) and the poles (P, Ps) have a radial magnetization that stabilizes the resetting of magnetic field to zero gauss, by the pole (Pc).</p> |
