Linear-induction motor, e.g. for high-speed magnetic-levitation vehicle

摘要

A linear-induction motor for a high-speed magnetic-suspension or magnetic-levitation vehicle comprises a U-section ferromagnetic rail having all three internal surfaces of the U formed with reaction layers of conductive material. The stator comprises a plurality of axially spaced annular windings connected in accordance with rotating-field polyphase principles and a core comprising two adjoining stacks of magnetic-metal sheets oriented in different directions for improved rigidity.
