Title: Max W Schulz, Jr: Innovator in Induction Motor Technology
Introduction
Max W Schulz, Jr is a notable inventor based in Scotia, NY (US). He has made significant contributions to the field of induction motors, holding a total of 3 patents. His work focuses on detecting rotor faults, which is crucial for the efficient operation of induction motors.
Latest Patents
One of his latest patents is the "Rotor fault and location detector for induction motors." This invention provides a method and apparatus for detecting rotor faults in an induction motor. The system utilizes a coil wound around one of the stator teeth to detect the flux around the rotor bars. A synchronization signal is generated once per revolution of the rotor, allowing for precise detection of rotor bar faults. The detected flux signal is filtered and time-averaged to identify statistically significant peaks that indicate the presence of rotor bar faults.
Another significant patent is the "Rotor fault detector for induction motors." This invention involves a flux sensor that generates a flux signal corresponding to the magnetic flux at a predefined detection point outside the motor. A current sensor generates a current signal proportional to the motor's current draw. The data is analyzed using Fast Fourier Transform (FFT) to determine the line frequency and slip frequency of the motor. By comparing the amplitude of the current spectra at specific rotor fault harmonic frequencies with predefined fault threshold criteria, the presence of rotor faults can be identified.
