Magnetic bearing module having a magnetic bearing

A magnetic bearing module comprising:

• a position sensor having a first connection face and a second connection face opposite the first connection face;
• a complementary bearing having a connection face mounted axially in contact with the second connection face of the position sensor;
• and
• a magnetic bearing having a connection face mounted axially in contact with the first connection face of the position sensor;
• wherein one of the first connection face of the position sensor and the connection face of the magnetic bearing is provided with three pegs, each peg having a shape exhibiting symmetry of revolution of which the axis is parallel to the axis of the module, an angular spacing between the first peg and the second peg being 90°, an angular spacing between the second peg and the third peg being 90°, the other of the first connection face of the position sensor and the connection face of the magnetic bearing has three accommodating first notches inside each of which is mounted one of the three pegs;
• wherein the connection face of the complementary bearing has three accommodating second notches inside each of which is mounted one of the three pegs.
