Abstract
The first idea of an - in the main propulsion emgine flywheel integrated - elecric generator-motor - booster emerged in .2002 but was - due to the expected problems with the electonic control of the sistem - limited to research of a high-frequency electric generator. This generator should be integrated in the flywheel of the main propulsion engine of a pleasure boat. Powerful permanent magnets are applied for the generator rotor, and the problem of sliding contacts, reliability and longevity of the engine was eliminated. Overall engine dimensions remained unchanged and the reliability improved by omission of the conventional V-belt-driven alternator. Besides there is no more need for an additional driving and space consuming combustion engine for the generator with its bad emission characteristic. A powerfull controller and rectifier supply electric current to a twin-batery sistem and to a DC/AC 220 V output inverter. If a special controller is apllied, a supplementary integrated starter - booster motor is obtained and helps to improve the dynamic response of the main engine. This booster motor can also be applied as a single, most reliable and ecologically convenient surce of power when cold starting and maneouvreing procedure in a harbour is concerned.
Numerical simulations of some electrical and mechanical features of the new generator model , its principal design, make of the first physical model have been performed. The results obtained will serve for the design of the first prototype to be built in the specially designed flywheel. Different design versions of the prototype generator with its periphery will be prepared and tested to determine optimum performance characteristic: an original cooling system and special power transmi ssion systems will also be included in the proposed two-years project work. Besides numerical simulations of the demand for extra power (of the integrated motor-booster) during the fast accelleration of the main propulsion engine will be determined and will form the base for the design of a model of an integrated electric motor-booster for pleasure boat application.
