NON-CONVENTIONAL SUPPLY OF VARIABLE SPEED DRIVES

摘要

Since legislative authorities in the USA demand for electrical automobiles, an increasing interest in electrical zero emission vehicles can be stated. Therefore, reinforced research on adapted drive systems and batteries for the supply are continued, starting from experiences from the past decades. We already started with activities to contribute to the various discussions in this field. In this paper, the methodology and the way of development of an electromagnetic variable speed drive system supplied by fuel cells is discussed. Starting with the properties of a single fuel cell up to a system concept for the electromagnetic energy converter, different possibilities to design a modular drive system are given in a technological discussion. As an application for this system concept an urban mini-bus is discussed. Due to the modular concept, the requirements for the power range of a medium sized delivery van can be reached.
