IMPULSE RING FOR A BEARING ASSEMBLY, BEARING ASSEMBLY COMPRISING SUCH AN IMPULSE RING AND ROTARY ELECTRICAL MACHINE COMPRISING SUCH A BEARING ASSEMBLY

摘要

This impulse ring (2) for a bearing assembly comprising a rotative element on which the impulse ring (2) is mounted, is rotatable with respect to a fixed sensing element adapted to detect a magnetic field generated by the impulse ring (2). The impulse ring (2) comprises at least one pair of magnetic poles (N, S) or at least one magnet (4) with north poles (N) and south poles (S) alternatively arranged along its circumference. The intensity of the magnetic field generated by the north poles (N) is different from the intensity of the magnetic field generated by the south poles (S).
