Incremental magnetic encoder

An incremental magnetic encoder defining an encoder axis and comprising a fixed body and a movable body movable with respect to the fixed body along at least a first direction of encoding corresponding to a translation along the encoder axis according to a predetermined translation travel length, the movable body being movable with respect to the fixed body further in a second direction of encoding perpendicular to the first direction of encoding and corresponding to rotation about the encoder axis;

• one of the bodies, called first body, comprising:
• a first ring extending along a first longitudinal direction coinciding with the encoder axis and a first circumferential direction perpendicular to the first longitudinal direction, the first longitudinal direction corresponding to the first direction of encoding, the first ring defining a magnetic alternation along the first direction of encoding;
• a second ring extending along a second longitudinal direction coinciding with the encoder axis and a second circumferential direction perpendicular to the second longitudinal direction, the second circumferential direction corresponding to the second direction of encoding, the second ring defining a magnetic alternation along the second direction of encoding;
• the other body, called second body, comprising:
• at least one first notching tooth made of ferromagnetic or magnetic material arranged opposite the first ring so as to create a notching during a movement of the movable body along the first direction of encoding;
• a first pair of magnetic detectors arranged opposite the first ring and configured for quantifying each movement of the movable body along the first direction of encoding;
• at least one second notching tooth made of ferromagnetic or magnetic material arranged opposite the second ring so as to create a notching during a movement of the movable body along the second direction of encoding;
• and
• a second pair of magnetic detectors arranged opposite the second ring and configured for quantifying each movement of the movable body along the second direction of encoding.
