Title: Motor monitoring method and apparatus using high frequency current components

Full Record
Other Related Research

Abstract

A motor current analysis method and apparatus for monitoring electrical-motor-driven devices. The method and apparatus utilize high frequency portions of the motor current spectra to evaluate the condition of the electric motor and the device driven by the electric motor. The motor current signal produced as a result of an electric motor is monitored and the low frequency components of the signal are removed by a high-pass filter. The signal is then analyzed to determine the condition of the electrical motor and the driven device.

Monitoring method and apparatus using high-frequency carrier

Patent Haynes, Howard D [Knoxville, TN]

A method and apparatus for monitoring an electrical-motor-driven device by injecting a high frequency carrier signal onto the power line current. The method is accomplished by injecting a high frequency carrier signal onto an AC power line current. The AC power line current supplies the electrical-motor-driven device with electrical energy. As a result, electrical and mechanical characteristics of the electrical-motor-driven device modulate the high frequency carrier signal and the AC power line current. The high frequency carrier signal is then monitored, conditioned and demodulated. Finally, the modulated high frequency carrier signal is analyzed to ascertain the operating condition of themore » electrical-motor-driven device. « less

Method and apparatus for monitoring motor operated valve motor output torque and power at valve seating

Patent Casada, Donald A [Oak Ridge, TN]

A method and apparatus are provided for monitoring a motor operated valve during the brief period when the valve seats and the torque switch trips to deenergize the valve motor. The method uses voltage measurements on the load side of a deenergizing switch that opens to deenergize the motor to determine, among other things, final motor rotational speed and the decelerating torque at motor deenergization.

Method and apparatus for generating motor current spectra to enhance motor system fault detection

Patent Linehan, Daniel J [Knoxville, TN]; Bunch, Stanley L [Oak Ridge, TN]; Lyster, Carl T [Knoxville, TN]

A method and circuitry for sampling periodic amplitude modulations in a nonstationary periodic carrier wave to determine frequencies in the amplitude modulations. The method and circuit are described in terms of an improved motor current signature analysis. The method insures that the sampled data set contains an exact whole number of carrier wave cycles by defining the rate at which samples of motor current data are collected. The circuitry insures that a sampled data set containing stationary carrier waves is recreated from the analog motor current signal containing nonstationary carrier waves by conditioning the actual sampling rate to adjust withmore » « less

Method and apparatus for improved efficiency in a pulse-width-modulated alternating current motor drive

Patent Konrad, Charles E [Roanoke, VA]; Boothe, Richard W [Roanoke, VA]

A scheme for optimizing the efficiency of an AC motor drive operated in a pulse-width-modulated mode provides that the modulation frequency of the power furnished to the motor is a function of commanded motor torque and is higher at lower torque requirements than at higher torque requirements.
