4. Use of linear motors in high-speed rail brakes
High-speed linear asynchronous motors with a double inductor on an aluminum central plate disappeared after 1980, to be replaced by those with a single inductor and composite armature in aluminum or copper plate, retaining a magnetic steel support part mounted flat between normal track rails. The induced rail tests carried out between 1967 and 1974 mainly concerned pure linear brakes on rails, for future high speeds (figure 10 ). As a reminder, double-inductor prototypes were produced after and outside America, for applications at much lower speeds, and on short-distance links. On the other hand, remaining in the high-speed domain, and with no direct correlation with the Pueblo models, a double linear descent took place with single inductors:...
