摘要： A homopolar reluctant sensor comprises a magnetic material rotor including a cylindrical body having at a first end a laminated part comprising the same number of lobes as there are sensor pole pairs and at a second end a ring and a magnetic material stator comprising a cylindrical portion provided with an excitation coil energized by an alternating supply, a first ring having notches and defining with said laminated part a first airgap and a smooth second ring defining with said rotor ring a second airgap. The stator notches are provided with a winding such that the voltage induced therein is sinusoidal and free of harmonics. The envelope of this voltage represents, apart from a phase-shift, the position of the rotor relative to the stator.

摘要： A sensor for measuring the angular position of a rotor relative to a stator has firstly a rotor made of a magnetic material and including 2 p lobes, where p is an integer. A stator is positioned around the rotor. The stator is made of a magnetic material and includes a number of teeth equal to 2n.p, where n is the number of phases of the sensor. Each tooth is surrounded both by an excitation first winding and by reception second winding. The excitation windings are connected together in series and disposed on the teeth such that the windings on two circumferentially adjacent teeth produce magnetic flux in opposite directions. The set of said excitation windings are powered by an alternative current or voltage. The reception windings of the same phase and offset by 180 electrical degrees are connected together in series. The envelope of the signal at the terminals of each of the pairs of reception windings represent the angle of rotation of the rotor relative to the stator, to within a scaling factor.
