General Atomics (GA) is a pioneer in the research and development of innovative permanent magnets and linear motors to create clean, fast and efficient transportation solutions. GA's passive maglev system uses permanent magnetics on vehicles and linear synchronous motors on guideways to levitate and propel vehicles. Maglev systems do not require electric motors, engines, or fuel, and have no moving parts on the vehicle. The result is a clean, light-weight vehicle design that eliminates engine and wheel noise, and harmful emissions. By using permanent magnets for levitation, any requirement for overhead powerlines or electric third rails is eliminated, helping improve safety and environmental aesthetics.
GA was the first in the United States to build a full scale working maglev system, which operates on a 400-foot test track in San Diego, California. GA's Electromagnetic Systems Group (GA-EMS) provides design, prototyping and manufacturing capabilities for the Maglev system permanent magnets and linear motors. GA-EMS manufacturing offers the depth of experience and sophisticated machining, winding, milling, assembly, and test equipment for the production of these highly specialized components.
Passive Maglev – vehicles magnetically levitate above specially designed guideways. The Linear Synchronous Motor (LSM) provides forward propulsion in most maglev systems.
Halbach Array Magnet Configuration – increases magnetic field strength. Provides larger air-gap for less expensive guideway construction.
Magnet Blocks – divided into subassemblies and loaded into the magnet modules mounted to the chassis assembly supports.
Guideway Modules – includes Linear Synchronous Motor and levitation track. Supports high speed turns (144 km/hr, 90 mph), 800 meter minimum turn radius, 11.5 Cant Angle.
