Title: Christian John Gianni: Innovator in Motor Control Technology
Introduction
Christian John Gianni is a notable inventor based in Auckland, New Zealand. He has made significant contributions to the field of motor control technology, holding 2 patents that showcase his innovative approach to electronically commutated motors.
Latest Patents
Gianni's latest patents include a method and apparatus for controlling the speed of a multi-phase, brushless DC electrically commutated motor (ECM). This invention involves voltage commutation to the windings of the ECM based on rotor position information derived from back EMF or Hall effect sensors. The application of the commutating voltages is arranged such that the voltage applied to the windings always leads the back EMF generated in the windings by a selected constant lead angle. The speed of the motor is controlled by pulse width modulating (PWM) the voltage applied to the windings of the ECM. Another patent focuses on methods of and/or apparatus for electronically commutated motor control, disclosing a method of controlling the commutation of power to an electric motor using back EMF sensing or Hall effect sensors. This invention senses at least part of the current waveform in at least one motor winding to establish information relating to the appropriate commutation pattern required to control motor parameters such as speed.
