Abstract: A magnetic bearing module (1) having a position sensor (2) and a magnetic bearing (3) is disclosed. One of a connection face (5, 6) of the position sensor (2) and a connection face (9) of the magnetic bearing (3) is provided with three pegs (22, 23, 24). Each peg has a shape exhibiting symmetry of revolution of which the axis (L22, L23, L24) is parallel to the axis (L1) of the module (1). The angular spacing between the first peg (22) and the second peg (23) is 90°. The angular spacing between the second peg (23) and the third peg (24) is 90°. The other of the connection face (5, 6) of the position sensor (2) and the connection face (9) of the magnetic bearing (3) has three accommodating notches (32, 33, 34) inside each of which is mounted one of the three pegs (22, 23, 24).

Abstract: A method for estimating the temperature of a stator coil of a magnetic suspension bearing of a rotor that is connected by connection wires to circuits for servo-controlling the position of the rotor includes the following steps: measuring the electric voltage at the terminals of the connection wires of the stator coil; measuring the intensity of the current passing through the stator coil; estimating the electric resistance of the stator coil and of the connection wires on the basis of an adaptive filter, the measured electric voltage and the intensity of the measured current; and estimating the temperature of the coil on the basis of the value of the estimated resistance.

Abstract: A device for estimating the sensitivity of a position sensor for a magnetic bearing supporting a rotor, the sensor being capable of measuring the position of the rotor in relation to the magnetic bearing, the magnetic bearing including at least one shaft provided with at least two radially opposite coils. The device includes a control, a current-measuring component, a component for measuring the initial position of the rotor, a component for determining a variation in currents, a component for determining a movement of the rotor, and a component for determining the sensitivity of the sensor, configured to determine the sensitivity of the position sensor based on a movement setpoint and on the value of a movement of the rotor.
