Title: Francesco Giuffré: Innovator in Motor Control Technologies
Introduction
Francesco Giuffré is a notable inventor based in Messina, Italy. He has made significant contributions to the field of motor control technologies, holding 2 patents that showcase his innovative approach to engineering challenges.
Latest Patents
One of his latest patents is focused on the detection of the angular position of the rotor of a brush motor without using sensors. This method involves detecting switching ripple peaks and armature current disturbance peaks using a peak detector. The generated square wave has edges that coincide with the detected peaks. The method further includes filtering the square wave in the time domain by generating an integration ramp toward a set value based on the estimated ripple frequency. An enablement range is established to reset the integration ramp, ensuring accurate detection of the rotor's position.
Another significant patent by Giuffré is a method and circuit for controlling an electric power plant. This control circuit is designed for an electric power plant that includes an asynchronous generator of AC voltage. It features a motor that rotates the rotor of the asynchronous generator based on a control signal related to the developed motor torque. The circuit also includes a bank of capacitors whose total capacitance varies according to a second control signal. This innovative design aims to maintain the desired amplitude and frequency of the AC voltage.
