For inspection and maintenance of large facilities made of steel material, vehicles being designed to wander on steel plates are much in demand, especially in situation like ship hulls and surfaces of large oil tank. A novel propulsion strategy for such vehicles based on the theory of electromagnetism was presented recently. The proposed vehicle applies pedrails structure mechanically, and the pedrails...
Based on the theory of linear induction motor (LIM), this paper presents a strategy for driving vehicles climbing on erect steel plates. The novel strategy makes use of the steel plate as partial magnetic circuit of the LIM, which can provide thrust and attractive force simultaneously, and consequently, the vehicle structure is simplified. Experiment result obtained from a prototype shows the validity...
