In the text lessons of this module, Nigel dives into considerable detail with respect to the trending topic of Electric & Hybrid Propulsion in recreational marine applications. The lessons of this module are based on extensive original research that Nigel conducted funded by the European Union. The lessons contain a wealth of experimental results that are a valuable resource for any boater seriously considering replacing a diesel engine with an electric or hybrid system. The articles of the module are highly technical and aimed at professionals or boatowners who have a very deep interest in the details of such systems.
Electric & Hybrid Propulsion
What are the key characteristics of purely electric propulsion systems as well as serial and parallel hybrid installations?
One of the promises of electric propulsion is the ability to generate energy while under sail. We examine under what conditions this is possible and what output can be expected with various propeller types and electric motors.
We learn about different types of electric motors and their efficiency in bringing power to the propeller shaft.
In conjunction with Scott McMillan of Electric Yacht, Nigel has undertaken considerable electric propulsion motor testing, including regeneration, using his boat ‘Nada’. In this extensive article, he presents the results of their efforts to optimize the performance of an electric motor over a wide range of power demands and rpm via dynamic setting of torque control.
