Nettet1. mar. 2024 · The short stator Linear Induction Motor (LIM) is normally used in mid-low speed maglev trains. The restriction by mounting space on bogies and motor input voltages lead to that maglev train speed ... The history of linear electric motors can be traced back at least as far as the 1840s to the work of Charles Wheatstone at King's College in London, but Wheatstone's model was too inefficient to be practical. A feasible linear induction motor is described in US patent 782312 (1905; inventor Alfred Zehden of Frankfurt-am-Main), … Se mer A linear induction motor (LIM) is an alternating current (AC), asynchronous linear motor that works by the same general principles as other induction motors but is typically designed to directly produce motion in a … Se mer A linear electric motor's primary typically consists of a flat magnetic core (generally laminated) with transverse slots that are often straight cut with … Se mer Thrust The drive generated by linear induction motors is somewhat similar to conventional induction motors; the drive forces show a roughly similar characteristic shape relative to slip, albeit modulated by end … Se mer Because of these properties, linear motors are often used in maglev propulsion, as in the Japanese Linimo magnetic levitation train line … Se mer In this electric motor design, the force is produced by a linearly moving magnetic field acting on conductors in the field. Any conductor, be it a loop, a coil, or simply a piece of plate metal, that is placed in this field will have eddy currents induced in it thus creating an … Se mer Linear induction motors are often less efficient than conventional rotary induction motors; the end effects and the relatively large air gap that is … Se mer • Electromagnetic induction • Goodness factor • Maglev • Tracked Hovercraft Se mer
