Innovative Electric Propulsion Systems for Aviation and the Nautical Industry

The publication presents two innovative solutions of drive systems recently developed at the Łukasiewicz – Upper Silesian Institute of Technology, Center of Electric Drives and Machines. The first one is an integrated drive unit with a power of 21 kW, dedicated to floating vessels, in particular houseboats. The drive is characterized by a compact design and high energy efficiency. The second solution is a LEMoK 300 motor with a maximum power of 90 kW, dedicated to small aircraft. The motor only weighs 18 kg and has very high power density, which allowed its direct use in a prototype hybrid aircraft. Both solutions were developed in cooperation and at the request of business partners, i.e. Sun Yacht – Boating Holidays and Artus Aircraft. The paper presents the primary operational characteristics and data of the design solutions developed by the Authors.
