A rotating electric machine includes a rotor and a wound stator. The wound stator has a stator shaft, wherein the stator coils are inserted in the rotor, and the stator shaft is inserted in the center of the rotor. At least one angular position sensor of the rotor is inserted in the center of the space delimited by the stator shaft and the rotor.

A method for measuring the hardware and operational state of a dual-circuit solenoid valve including first and second coaxial coils each associated with a circuit is disclosed. The method includes the steps of injecting a sinusoidal current into the first coil; measuring the voltage induced across the terminals of the second coil; and plotting at least one curve of a first magnitude proportional to the measured induced voltage as a function of a second magnitude proportional to the injected sinusoidal current.
