A novel design of electric tire concept incorporating permanent magnet linear generators arrangement

Growing concerns due to environmental impact of extensive fuel combustion by on-road transportation have emphasized the need for alternative solution to the on-board power generation. This paper proposes a novel method to generate electricity on board a vehicle by using local changes in pressure and shape of a pneumatic tire while vehicle is moving. Arrangement of a set of generators incorporated inside a vehicle's wheel is fully demonstrated in this paper. The paper proposes different generator configurations, and presents preliminary design and development of a linear permanent magnet generator using Finite Element Analysis.
