In another production workshop, the newly built flat wire motor automatic production line with an annual capacity of 100,000 set/year has started batch production. Liu Jingda, administration director of the Company, told the reporter that this workshop produced leading and high-potential product of Santroll Electric, that is flat wire motor, core part of new energy automobile. "We started to test flat wire motor in 2015. After many years of patent accumulation, we finally met the requirements of testing parameters in 2017. Products used in 30 buses have been tested, and the results show no product needing repair after the buses using the products have travelled more than 100,000 kilometers." Liu Jingda was full of confidence when talking about product quality. Apparently, the change from round wire to flat wire is only a change in the shape of stator of the motor, but such change makes the motor smaller under the same power, with higher safety and reliability, higher efficiency, and longer traveling mileage. It is a milestone in terms of technical upgrading of products.
