Introduction

Parimelalagan Ramachandran is an accomplished inventor based in Ozark, MO (US). He has made significant contributions to the field of motor control systems, holding a total of three patents. His work focuses on enhancing the efficiency and performance of blower systems through innovative control algorithms.

Latest Patents

One of his latest patents is titled "Control algorithm for brushless DC motor/blower system." This invention provides an apparatus and method for controlling a brushless direct current motor with a pulse width modulated variable frequency drive. The system is designed to ensure that the blower provides a specific fluid flow. A start-up program enables the motor to ramp up to a predetermined steady state speed. The required blower torque is calculated using a table of blower constants, a selected flow rate, and motor speed, which is read from a commutation Hall sensor. The developed motor torque is also calculated, and the system continuously compares the required blower torque with the developed motor torque to achieve a steady state.

Another notable patent is the "Speed computation function for induction motor/blower systems control algorithm." This invention outlines a method for controlling an induction motor with a variable frequency drive in a blower system. Similar to his previous patent, it ensures the blower system provides a specific fluid flow. The start-up program ramps the motor to a steady state speed, and the required blower torque is calculated using a table of blower constants and motor speed. The developed motor torque is calculated, and adjustments are made to the voltage-frequency index to ensure the developed motor torque converges with the required blower torque.
