Webb31 okt. 2024 · Different from rotating induction motor (RIM), linear induction motor's (LIM's) structure is asymmetric and its secondary part consists of a sheet of aluminium with a back core of iron . When the primary part moves, new continuous eddy currents appear at the entry of the primary part and disappear at the exit part [ 2 ]. 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
