WebbYamamamura [1] reviewed the basic theory and ana-lyzed the structures of several types of LIMs in details. He stated that the essential difference between the LIM and the rotary induction motor is the open linear air gap due to the entry and exit end of the LIM. He also pre-sented the three-dimensional analysis of the LIM to ana- 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 straight line. Characteristically, linear induction motors have a finite primary or secondary length, … Visa mer 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 … Visa 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 coils laid into the slots, with each … Visa 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 … Visa mer Because of these properties, linear motors are often used in maglev propulsion, as in the Japanese Linimo magnetic levitation train line near Nagoya. The world's first … Visa 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 … Visa mer Linear induction motors are often less efficient than conventional rotary induction motors; the end effects and the relatively large air gap that is often present will typically reduce the forces produced for the same electrical power. Similarly, the efficiency during … Visa mer • Electromagnetic induction • Goodness factor • Maglev • Tracked Hovercraft Visa mer
