ABSTRACT:
A linear induction motor comprises an inductor that has a multiphase concentrated winding and a magnetic circuit made of a plurality of transversely laminated cores, and also comprises a secondary element having an electrically conductive member disposed on a magnetically conductive base. The yoke of each of said cores has a hole, a spring is located between each pair of adjacent cores, and a rod is adapted to pass through the holes and the springs, said rod being coupled with a regulation element. The invention makes it possible to accelerate and brake smoothly high-speed ground transportation vehicle so that more safe conditions for a vehicle's crew are provided.
