Title: Austin Hughes: Innovator in Electric Machine Control
Introduction
Austin Hughes is a notable inventor based in Leeds, GB. He has made significant contributions to the field of electric machine control, holding a total of 3 patents. His work focuses on enhancing the performance and efficiency of electric machines through innovative methods and apparatus.
Latest Patents
One of his latest patents is an "Apparatus and method for controlling an electric machine." This invention involves a controller for an electronically commutated electrical machine that receives a feedback signal indicative of a parameter to minimize, such as torque ripple, current, voltage, vibration, or acoustic noise. The controller computes the amplitude and phase of a set of harmonics in the parameter and sequentially injects harmonics of the correct amplitude and phase to minimize the parameter. An optimizing routine iterates through the set of harmonics to further reduce the parameter.
Another significant patent is related to "Electric stepper motors." This invention describes an electric stepper motor that includes, in addition to the usual driving coils, at least one additional coil wound on its stator and connected in a closed circuit. This additional coil serves to damp any oscillations of the rotor. The closed circuit has a resistive value optimized to achieve maximum damping effect. Furthermore, two or more such additional coils may be connected in a single closed circuit, and multiple closed circuits may be provided.
