Recently, the Economy andInformation Technology Department of Zhejiang publicized the list of the First Unit(Set)of Major Technical Equipment in Zhejiang Province in 2022. After evaluation byexperts and at all levels, the “XT2300-800-217C700kW Cable Car Direct-DriveSystem” developed by Ningbo Physis Technology Co., Ltd. (hereinafter referredto as Physis) was recognized as the First Unit(Set) of Major TechnicalEquipment in China because of its innovative and advanced dynamic performance.The “first unit (set) of major technical equipment” means the key technicalequipment that is the first in China to achieve major technologicalbreakthroughs, owns the independent intellectual property, and has not yetachieved market performance. In this list, only 18 enterprises in Ningbo wereselected. As the only enterprise in Beilun District of Ningbo City selected asthe “first unit (set) of major technical equipment in China”, Physis has madenew strides in the field of advanced manufacturing capabilities and R & Dand innovation capabilities.
To take the initiative andjoin forces to gain an upper hand in the market. The success ofXT2300-800-217C700kW Cable Car Direct-Drive System benefits from the planningand layout of Physis two years ago. In November, 2020, Ren Wenjie, President ofPhysis, and Huang Yuefeng, Deputy General Manager of Beijing Materials HandlingResearch Institute Co., Ltd. signed a cooperation agreement on behalf of bothsides, and reached a cooperation on the research and development of megawattdirect-drive electric drive system and 700kW prototype system of cable car.Beijing Materials Handling Research Institute Co., Ltd. is a leading enterprisein the cable car industry in China, while Physis has always kept pace with theinternational advanced technology in the research and development ofdirect-drive system. The two sides have realized a powerful combination withmutual complementarity, formed a long-term cooperative partnership by usingtheir technical advantages and market influence to carry out in-depthcooperation on the development and industrialization of megawatt direct-driveelectric drive system of cable cars.
To practise basic skillsand deepen the popularization and application of direct-drive system. Physishas been focusing on the development and application of direct-drive system fornearly twenty years, and its direct-drive system has been widely used inhigh-end machine tools, military radar turntable, high-precision astronomicaltelescope, high-speed elevator, fluid dynamic, coal mine belt conveyor andother industries. The traditional driving mode of motor plus reducer has someshortcomings, such as oil leakage, vibration, overheating and loud noise, whichwill reduce the continuous operation capacity and reliability of equipment. Thesuccessful development of XT2300-800-217C700kW cable car direct-drive systemdirectly connects the low-speed and high-torque direct-drive motor to thedriving wheel. Compared with the traditional motor plus reducer drive, thedirect-drive system directly eliminates a series of shortcomings brought by thereducer and improves the comfort, reliability and transmission efficiency ofthe cable car transmission system.
To proactively andcontinuously develop multi-scenario applications. In recent years, with thepopularization and deepening of the concepts of smart home, industrialautomation and logistics automation, many new technical requirements haveappeared in various drive systems in the household appliances, vehicle-mountedand industrial fields that are closely related to everyone. Physis keeps pacewith the times and is committed to promoting leading smart power technology anddeeply integrating it into all fields of the industry.
