Title: Harindra Rajiyah: Innovator in Induction Machine Technology
Introduction
Harindra Rajiyah is a notable inventor based in Clifton Park, NY (US). He has made significant contributions to the field of induction machine technology, holding a total of 9 patents. His work focuses on advanced methods and systems that enhance the performance and efficiency of rotating machinery.
Latest Patents
One of his latest patents is titled "Method, system, and computer-readable medium for sensorless measurement of induction machine rotor bar pass frequency." This innovative method involves sampling a current waveform of an induction machine to obtain sampled points. It characterizes the sampled current over a selected first time window to obtain characterized points. The method then subtracts the characterized points from the respective sampled points to obtain a residual signal comprising residual points. A frequency spectrum representative of the residual signal is obtained over a selected second time window, allowing for the identification of a rotor bar pass frequency from the frequency spectrum.
Another significant patent is the "Model-based method for optimized field balancing of rotating machinery." This method is designed for balancing a rotor of a rotatable machine, such as a steam turbine-generator unit. It formulates a time-dependent equation for rotor vibration based on a rotordynamic computer model derived from finite element analysis. The equation is repeatedly solved in the frequency domain as an optimizer program uses iteration to determine the unbalance weights that will cause the vibration of the rotor of the model to duplicate the measured vibration of the rotor of the machine.
