摘要： Apparatus which automates the collection of motor temperature, flux and shaft current data for proactive motor maintenance. Motor speed is determined by an analysis of the flux frequency spectrum, and motor load is determined based on speed, from which a normalized thermal parameter is then determined. From a spectrum analysis of magnetic flux signals a set of peaks each characterized by a frequency and an amplitude is found, and a subset of peaks is identified in accordance with predetermined identity criteria for purposes of comparison. Temperature, magnetic flux and shaft current data are trended to provide early indications of degradation, as well as for recognizing faults.

摘要： Apparatus for determining the rotational speed of an AC induction motor based on a spectrum analysis of a magnetic flux signal. For a Phase I analysis, which is usually sufficient, three sets of families of peaks indicative of possible rotational speeds are defined, and the flux frequency spectrum is searched for peaks meeting the family definitions to determine candidate speeds, and to assign scores. If there is a candidate speed with an overall score which exceeds a predetermined threshold, the motor rotational speed is determined as that candidate speed. A Phase II analysis, employing a more exhaustive set of five additional family definitions, is applied when Phase I fails to reach a result.

摘要： A method for nonintrusive detection of anomalies in electric machines. A flux coil is positioned external to the motor to obtain magnetic leakage flux measurements, which are transformed to the frequency domain to obtain a flux spectrum. Asymmetry-producing faults, such as turn-to-turn stator winding shorts, produce changes in the amplitudes of individual frequencies and groups of frequencies within a defined slot pass family of frequencies of the flux spectrum. The measured amplitudes of the slot pass family of frequencies are compared to reference and trend data. Significant changes in the slot pass frequency amplitudes indicate the presence of a machine fault or other anomalous condition. Significant changes are determined by comparing individual amplitudes and groups of amplitudes of the slot pass family of frequencies to an absolute or delta threshold value. Alternatively, measured amplitudes of the slot pass frequencies can be statistically compared to trend data previously acquired for the motor to determine when a significant change in the slot pass amplitudes has occurred.

摘要： A viscosity tester includes a free standing magnetic object disposed in fluid in a stationary receptacle. A magnetic force drives the object in an orbit and the magnetic force, the speed of the object and the lag angle between the magnetic field and the object are either measured or controlled and, based on at least one of these three parameters, the viscosity of the fluid is determined. In one embodiment, a magnetic ball is driven by four electromagnets, with proximity sensors detecting the presence of the ball and controlling the electromagnets. In another embodiment, a free standing magnet is driven in an orbital pattern by a rotating field that is coaxial with the orbital pattern and is produced by a rotating magnet or a stator.

摘要： The invention provides a computerized method and apparatus which enables a user, even one who has little or no predictive maintenance skills, to establish a predictive maintenance database that defines information needed to monitor equipment in accordance with a predictive maintenance plan. The type of equipment components to be monitored and associated physical characteristics of the components are input to a computer as an equipment configuration, which may include one or more interconnected components. The computer includes a knowledge base that defines relationships between monitoring practices, component types, and physical characteristic information for component types. A predictive maintenance database is constructed for the components using the inference engine operating on the knowledge base, the selected component type, and the selected physical characteristic information. Multiple measurement technologies may be specified for each component. Preferably, for each measurement technology specified, the predictive maintenance database includes measurement points, an analysis parameter set, and an alarm limit set. Equipment configurations may be defined by the user, or they may be stored in a configuration/component warehouse with little or no configuration definition required of the user.

摘要： A portable data collector and analyzer having multiple paths for performing multiple processing functions on a single sensor signal in parallel. The portable data collector has a sensor which creates a sensor signal that represents a measured property of an operating machine. The sensor signal is simultaneously sent to at least two processor channels that are connected in parallel. Each processor is capable of performing different types of signal analysis with varying signal conditioning and sampling rate requirements on the sensor signal independent of the other processor(s). An operator of the parallel processing data collector and analyzer places the single sensor on the area desired to be tested and instructs the parallel processing data collector to begin taking measurements. The parallel processor channels work independently of each other to obtain results corresponding to a number of different tests in approximately the time normally required to perform a single test.
