First, high speed IMs use contact bearings  or AMBs - , while bearingless IMs integrate the functionality of AMB. Second, high speed IMs can use slit solid rotors, coated solid rotors. The ideal characteristics of an electric motor drive for traction application in an electric and hybrid electric vehicle are high torque at low speed region for fast acceleration, hill climbing. LINEAR MOTORS TO POWER DOT'S HIGH-SPEED RESEARCH VEHICLES. Linear electric machines are generally considered indispensable for the propulsion of tracked vehicles at km/h and above, As part of the US Department of Transportation's research program at Pueblo, two multi-megawatt LIM propulsion systems have been built by Garrett for rail and levitated by: 3. The system is designed with the following objectives: â€¢ High-speed passenger transportation â€“ greatly exceeding the speed capability of high-speed rail and conven- tional trains, and exceeding the speed of fossil-fuel-dependent airline jet flights. â€¢ High-frequency departures: passengers need not plan a trip long in advance.
Variable speed drives with induction motors are used in transportation, pumps, compressors, ventilators, machine tools, robotics, hybrid or electric vehicles, washing machines, etc. The forecast is that, in the next decade, up to 50% of all electric motors will be fed through power electronics with induction motors covering 60 to 70% of. In the s, the last American company building electric road vehicles stopped production. It took until when General Motors Research & Development integrated a silver–zinc battery originating from the US space program and electric motors in a Corvair-based EV, the Electrovair (see Figure (a)).In , GM R&D developed the GM Electrovan (Figure (b)), the . torque-coupling and speed-coupling hybrids, and other configurations. The major operating characteristics of these configurations are presented. In Chapter 6, several electric propulsion systems are introduced, including DC, AC, permanent magnet brushless DC, and switched reluctance motor . Some examples are wind generators , motors for ship propulsion , and linear motors for high-speed conventional or levitating trains or Hyperloop
Linear electric motors (LEMs) have a potential of applications in aircraft launching systems, manufacturing processes, inspection, flight control actuators, fuel pumps, propulsion motors for. Linear Synchronous Motors: Transportation and Automation Systems by Jacek Gieras et al. CRC Press, / A History of Linear Electric Motors by Eric Laithwaite. Macmillan, Supertrains: Solutions to America's Transportation Gridlock by Joseph Vranich. St . The Hyperloop is a proposed mode of passenger and freight transportation, first used to describe an open-source vactrain design released by a joint team from Tesla and SpaceX. Hyperloop is a sealed tube or system of tubes with low air pressure through which a pod may travel substantially free of air resistance or friction. The Hyperloop could convey people or objects at airline or hypersonic. Considered to be the first book devoted to the subject, Linear Synchronous Motors: Transportation and Automation Systems, Second Edition evaluates the state of the art, demonstrating the technological innovations that are improving the design, construction, and performance of modern control systems. This new edition not only illustrates the development of linear synchronous motor drives, but.
