摘要： A speed detecting device includes an excitation coil for generating a magnetic flux corresponding to an alternating current, a plurality of detection coils each generating an induced voltage corresponding to a magnetic flux produced by an eddy current generated on a conductive relative moving body, the eddy current being generated so as to correspond to a moving speed of the relative moving body moving through the magnetic flux generated by the excitation coil, a gap estimation portion for estimating, based on a current flowing through the excitation coil and a voltage across the excitation coil, a gap between the relative moving body and the excitation coil, and a speed estimation portion for estimating, based on the gap estimated by the gap estimation portion and the induced voltage generated in each of the plurality of detection coils, the moving speed of the relative moving body. By correcting the speed determination based on the gap, variations in the distance between sensor and body may be compensated.

摘要： A rotational sensing system is adaptable to sensing motor rotation based on eddy current sensing. An axial target surface is incorporated with the motor rotor, and includes one or more conductive target segment(s). An inductive sensor is mounted adjacent the axial target surface, and includes one or more inductive sense coil(s), such that rotor rotation rotates the target segment(s) laterally under the sense coil(s). An inductance-to-digital converter (IDC) drives sensor excitation current to project a magnetic sensing field toward the rotating axial target surface. Sensor response is characterized by successive sensor phase cycles that cycle between LMIN in which a sense coil is aligned with a target segment, and LMAX in which the sense coil is misaligned. The number of sensor phase cycles in a rotor rotation cycle corresponds to the number of target segments. The IDC converts sensor response measurements from successive sensor phase cycles into rotational data.

摘要： A method (and corresponding apparatus) for monitoring gas turbine blades. The output from an eddy current sensor monitoring the movement of turbine blades past the sensor is processed to determine when the signal train from the sensor omits a signal or pulse corresponding to one of the shaft's full complement of blades. The signal processor compares sensed blade periods with average blade periods, by determining a ratio value. The number of omitted pulses is determined by comparing the ratio with typical ranges for a particular number of omitted pulses.
