| Research Abstract |
The thrust force, normal force and side force given by the single-sided linear induction motor are studied theoretically. Their analytical formula based on the two dimensional electromagnetic field are derived and proved to be effective enough to design practical equipments. From these results a simlified one dimensional model is shown to be useful to derive its kinetic control scheme. The interaction between linear motor and magnetic suspension system of a magnetic wheel is analyzed and the sensitivity approach is introduced from the result.
The normal and side force can be sppressed enough during the acceleration process with constant slip frequency control scheme, but its slip should be rather high. Then it reduces the operational energy efficiency. The compromize between efficiency and dynamic behaviour is discussed. The design scheme of linear induction motor to optimize these characteristics is also studied.
The design of the secondary rail has also influences on the side force. With suitable dimensioning and the constant slip frequency control scheme the force could compensate the lateral disturbance force. Such scheme is verified with simulational studies.
The theoretical results are compared with experimental data obtained by the test operation of a maglev transport HSST-03 in Tsukuba by EXPO'85 and in Vancouver by EXPO'86. The study shows that the theoretical analysis and the new control scheme is verified through the practical system.
