The linear motor hard-core equipment in the Zhongchuan Cup equipment innovation competition. The final of the 9th China Ocean Craft Design and manufacture competition and the China Ship Cup Equipment Innovation Competition was held on August 22-23 in the online mode as scheduled. In this final, the Dalian University team had a good performance and won five special awards, 10 first prize, 28 second prize. 

     It is reported that the five Grand Prize winners were the Dalian University of Technology "polar unmanned underwater icebreaker" (under the ice can be needed to achieve underwater icebreaker) , the Dalian University of Technology's "Planar tree-shaped wind turbine structure" (to cope with more complex sea conditions to achieve a wider range of offshore wind energy utilization) , the Dalian Maritime University's wave-harvesting friction nanogenerators, as well as "underwater automatic welding and cutting equipment" which can replace manual maintenance of underwater ships, light-weight and friendly surface cleaning vessels which can be used for garbage removal in small water areas... the China marine craft design and manufacture competition and the mid-ship Cup equipment innovation competition is a high-level, large-scale and wide-coverage science and technology competition in the field of ships and marine engineering in our country, all previous competitions have presented a feast of Science and technology. When it comes to equipment and technology research in the field of the ocean, devices with wave energy as the core have always been the focus of research in various scientific research institutions and universities, and this year is no exception, the Dalian Maritime University has created a friction nanogenerator that can harvest wave energy to power a network of ocean information sensors. 

     When it comes to wave power generators, linear motors have been used in a number of practical applications: the UK based Trident Energy's hydrofoil floating platforms have linear motors inside them, each producing 1MW of power, the test installation was carried out in 2009; the Archimedean Wave Energy conversion device developed in the Netherlands makes use of the pressure difference between the crest and the trough of the wave to generate relative motion to the conversion device, which drives the linear motor to generate electricity; of course, China is not to be outdone either, from 2006 to 2010(during the 11th five-year Plan period) , "Na Sha No. 1" , developed by Guangzhou Energy, Chinese Academy of Sciences, is a 10kW floating linear motor wave energy device. 

     Kunshan Tongmao Electronics Co. , Ltd. is a high-tech enterprise and brand chain enterprise integrating linear motor development, intelligent manufacturing and sales. TONGMAO LINEAR motor adopts European and American technical standards and processing technology, the quality and performance of the customer's praise.
