A few days ago, the 18th annual inventory activity affecting China's bus industry was held in Hefei, Anhui Province, and the EDM3500R three-in-one pure electric drive assembly was promoted by Jingjin Electric to participate in the evaluation, with its excellent performance in lightweight, high performance, high reliability and cost competitiveness, and won the "2023-2024 'New Energy Bus Electric Drive Technology Achievement Award'", which has become another innovative product to help the development of new energy buses.
EDM3500R assembly will drive motor, controller and reducer highly integrated integration, the system adopts composite cooling square conductor motor, silent reducer, high power density motor controller, the three parts are deeply integrated, the maximum output speed of the system can reach 2560rpm, the torque can reach more than 3500Nm, the peak power is more than 240KW, and the maximum efficiency is greater than 95%.
The deeply integrated three-in-one fixed-ratio drive system has the advantages of high reliability, low cost, light weight, high efficiency, no shift power interruption, and no shift failure common in multi-gear systems. Not only that, the system also cancels the three-phase high-voltage line of the whole vehicle, adopts a high-speed and high-efficiency flat wire motor, and the reducer decelerates and increases torque, which greatly reduces the motor body, reduces the use of rare earth and other non-ferrous metals, and achieves 50% lightweight and 20% reduction compared with the system of direct drive motor and controller.
Jingjin electric longitudinal fixed speed ratio three-in-one assembly product adopts the platform design concept, which pushes the high-speed deceleration scheme to a wider range of vehicle applications, and is perfectly suitable for 10 12-meter buses. At the same time, the product has been used with 14 23t sanitation vehicles.
With continuous cultivation and forge ahead, the EDM3000R bus drive assembly has won the "2022-2023 New Energy Bus Electric Drive Technology Achievement Award". The new generation EDM3500R three-in-one pure electric drive assembly of Jingjin Electric has been re-electric, which is a proof of the strength of Jingjin Electric Electric Electric Drive System to continuously break through itself.
For a long time, Jingjin Electric has been constantly innovating, maintaining leading technology, leading the progress of weight reduction, cost reduction and integration of commercial vehicle electric drive, insisting on quality first, consolidating customer service, and becoming an evergreen enterprise in the field of commercial vehicle electric drive.
