From 2017 to the present, Shanghai University has been cooperating with our company to purchase Jinyi permanent magnet motors for use in teaching research, project development and other topics. During this period, they ordered high-speed permanent magnet motors, low-speed direct-drive permanent magnet motors, six-phase permanent magnet motors and other motors for research projects. After their experimental tests, they were very satisfied with the quality and performance of Jinyi motors, which not only satisfied their requirements for permanent magnet motors. The subject research on magnetic synchronous motor has been confirmed by market projects, and Jinyi Motor will continue to be used in the future.
