Title: The Innovative Contributions of Andrew Hamilton Harson

Introduction

Andrew Hamilton Harson is a notable inventor based in Belfast, Ireland. He has made significant contributions to the field of electrical engineering, particularly in the development of high-speed alternator/motor technology. His innovative approach addresses critical issues related to eddy current loss, which is a common challenge in high-speed permanent magnet alternator/motors.

Latest Patents

Harson holds a patent for a high-speed alternator/motor that effectively mitigates eddy current loss. Eddy current loss occurs when leakage flux from rotor magnets flows through stationary electrically conductive materials, such as bearing housings. To combat this issue, his invention employs a magnetic flux barrier means designed to prevent magnetic flux leakage from the magnets to the stationary conductive materials. The flux barrier can consist of a diverter disk made from magnetically permeable material, which rotates integrally with the rotor, or a barrier ring made from electrically conductive material that remains stationary at the end of the stator, extending across the air gap between the rotor and stator. Harson's innovative design is encapsulated in his single patent.
