【正文】 oupling transformer。） ? 功率 1MVA的 400Hz（變比 1∶ 1）中頻變壓器的重量為 450 kg，短路電抗為 %，效率達 %。 （ Weight of 400 Hz intermediate frequency transformer with 1MVA power（ transformation ratio 1： 1） is 450kg,whose shortcircuit reactance is % and efficiency is %。） transformer traditional single phase AC lootive 4Quardant converter traction motor DClink circuit and snubber circuit electrical transformer frontend reactor intermediate frequency transformer secondary side converter inverter frequency converter 無齒輪的直接傳動 （ Gearless Direct Drive） ? 電動機直接套在輪軸上，電機產生的轉矩不經齒輪而是直接傳遞到輪對上去 ,可節(jié)省空間和費用。 (motor directly surrounds wheel axle and torque produced by motor directly transfers to wheel pair without through gear, which efficiently saves space and expense。 ) ? 直接傳動特別適合永磁同步牽引電動機傳動。 (Direct drive especially applys to permanent mag synchronous motor drive 。 ) 永磁同步牽引傳動系統(tǒng) (Permanent Mag Synchronous Traction Drive System) ? 高效（ high efficiency） ? 高功率密度（ high power density） ? 可控性（ controllability） ? 減少空間尺寸（ reduce space size） ? 無齒輪直接傳動（ gearless direct drive） AGV PM motor for AGV Italy’s NTV, has placed firm orders worth €650 million (US$953 million) for 25 trains (with options for 10 more), and has signed a maintenance contract with Alstom. Production of the first trains will begin in mid2022, and they will be delivered from 2022 onwards. Maximum rpm 4500 Traction power（ kW） 720 Braking power（ kW） 720 Continuous power（ kW） 720 Electric work (V) DC 3000 Polarity 12 Efficiency (RC) 97% Frame size (mm) 650 Frame length (mm) 650 diameter Total weight (kg) 730 Specifications of the PM motors for AGV BOMBARDIER Mitrac Permanent Mag Motor ZEFIRO (Bombardier) Bombardier Transportation announced (28 Sept. 2022) that its Chinese joint venture, Bombardier Sifang (Qingdao) Transportation Ltd., has been selected by the Chinese Ministry of Railways (MOR) to supply 80 ZEFIRO 380 very high speed trains (1,120 cars) for the country’s rapidly growing high speed rail work. ECO4 Technologies can create Energy Savings of up to 50% ECO4a suite of energysaving technologies base on the four er stones of: ?Energy ?Efficiency ?Ecology ?Economy E954/E955 Shinkansen (TOSHIBA) PM motor for E954 Rated power 350kW cooling Self ventilation Efficiency % Frame size The same as the induction motor of E2/E3 Weight 440kg Specifications of the PM motors for E954 For the E954/E955 type, permanent mag synchronous motor drive system that achieves high output, light weight, low noise, and high efficiency. HEMU400X (korea) The NextGeneration Highspeed Rail Technology Development Project seek to develop core technologies necessary for EMUtype highspeed (maximum of 400km/h) rail system based on the successful development of the Korean highsped train:HSR350X. The 30 key ponents such as permanent mag electric motors with 400Km/h of maximum velocity……
