With a total of two patents to his name, Scelba's work focuses on enhancing the efficiency and functionality of permanent magnet synchronous machines.
Latest Patents
One of Giacomo Scelba's latest patents is a "Sensorless rotor angle detection circuit and method for a permanent magnet synchronous machine." This innovative technology estimates the initial position of a rotor by monitoring sensed motor current signals. These signals are amplitude and phase modulated with the rotor flux position in response to a high-frequency voltage signal injection. The motor current signals are envelope detected to determine zero crossing points. Samples are taken of the motor current signals at positive and negative offsets from the zero crossing point, with the samples processed to identify a direction of the rotor flux axis. Further samples of at least one motor current signal are taken with respect to a certain phase reference, and the samples are compared to resolve a polarity of the rotor flux axis, which is indicative of the angular position of the rotor.
