When it comes to electric motors, many people feel more ambiguous, in fact, with the beginning of all the automobile industry to the new energy technology level, to this year in China will produce an annual output of two million new energy vehicles of a great business scale, but although the current policy and development trend of the natural environment is very good, but at this stage in the key industries of new energy technology there are still great shortcomings.
As one of the three key components of new energy vehicles, the "three electric systems" composed of electric motors, motor control and lithium battery packs are of great practical significance to new energy vehicles. Among them, the electric motor is the key driving organization of the battery car, and its advantages and disadvantages immediately jeopardize many performance parameters of the new energy vehicle. At this stage, in addition to the imbalance between the supply of lithium battery packs and the increasingly prominent production of new energy vehicles, the differences in motor supporting facilities have just begun to become more and more prominent.
When it comes to Chery Automobile, I firmly believe that everyone knows very well that Chery Automobile has already stepped into a full 20 years since its inception in 1997, and several models of its production and manufacturing have left their own marks in the history of China's automobile development. So what is the situation of Yaskawa Robotics, which is collaborating with Chery Automobile?
Yaskawa Electric was founded in 1915, nearly a hundred years ago, with a history of nearly 100 years, Japan Yaskawa Electric is the world's first-class transmission system commodity manufacturer, in the AC servo motor, soft starter and industrial manipulator and other industries to grasp the leading technology. In April 2017, Chery New Energy New Energy Technology Co., Ltd., Wuhu Capital Construction Project Investment Co., Ltd. and Japan's Yaskawa Electric Co., Ltd. established Chery Automobile Yaskawa Robot Electric Drive System Software Co., Ltd., with an initial capital investment of 300 million yuan.
At about eleven o'clock in the morning on December 28, 17, the first self-developed 95kW motor and control board of Chery Automobile Yaskawa Robot Electric Drive System Software Co., Ltd. withdrew from the production line in Wuhu, Anhui Province. This means that Chery Automobile Yaskawa Robot Co., Ltd. will show electric drive system software for Chery New Energy and new energy technology manufacturers with manufacturing qualification certificates in China in the future, so as to boost the development trend of new energy vehicles in China.
Regarding this matter, Yin Tongyue, CEO of Chery, said at the event that it is the key development strategy of Chery to actively implement China's green environmental protection development strategy and fully promote the development trend of new energy vehicles. This not only confirms that Chery Automobile has always maintained a strong overall strength in product research and development of important parts of cars, but also lays a solid foundation for the development and expansion of the new energy technology product system and the improvement of commodity competitive advantages.
Kenji Yamada, corporate manager of Chery Automobile Yaskawa Robotics, said that in addition to maintaining the overall strength of superior product research and development, the company will further enhance the additional use value of products in the future to create a first-class product reputation and brand effect for Chery Automobile Yaskawa Electric products. Chery Automobile's Yaskawa Robotics Company will eventually become the promoter of China's electric drive industry.
At this stage, Chery Automobile's Yaskawa Robot's product series already has the production capacity of multiple models and specifications of electric motors. In order to comply with the development trend of the sales market, the company will also focus on the development and design of freight logistics vehicles and BUS electric drive products, and gradually create a stronger competitive advantage.
According to the information obtained by Xiaobian from the front, the 95kw motor manufactured by Chery Automobile Yaskawa Robot has the characteristics of lighter net weight, higher efficiency of electric drive, and greater relative density of winding wire, integrating the winding wire conversion technology that is leading in its manufacturing industry, compared with China's current products, it has extraordinary main performance in the high efficiency of the driver, and the net weight of the entire equipment is alleviated by 22%. So how is this product manufactured, and what are the shining points in its production process, let's find out.
Dipping process:
The dipping process is a fixed process of coating the copper core wire, which must first heat the electromagnetic coil, drip into the topcoat, and then dry the topcoat according to the heating method, and finally accurately measure the adhesion of the topcoat. According to the previous dipping rotary dripping method, the demand for topcoat can be greatly reduced, and a progressing cavity pump is applied to the paint paint to complete the anti-aging of the coating amount.
Sealing and casting process:
The actual steps are to first install the core of the motor rotor transformer into the abrasive, put the magnet into the core of the motor rotor transformer, and place the epoxy resin in the abrasive tool after placement, and the complete process will be announced. The advantage of this process depends on the fact that the compressive strength can be achieved according to the addition of epoxy resin and its all-round fixation of the magnet.
Assembling experimental process:
The assembly process includes the assembly process of the motor rotor and the assembly process of the motor stator, and the final assembly of the motor is completed according to the skilled automation technology management system and architecture hot assembly work and the automation technology of the motor rotor balance adjustment work.
After the assembly, according to the tracking system software, the records of each process can be carried out in a unified management method, and the finished products can be inspected according to the inching and negative load detection of 12,000 revolutions per minute, so as to avoid the injection of unqualified products into the sales market, and finally a testing process, which can be said to be of great benefit to improving the product qualification rate of Chery automobile safety motors.
Chery Automobile Yaskawa Robot Enterprise focuses on the product development and manufacturing of new energy technology drive motors and control panels, and sets up the production of motors in the early stage, and finally completes the production scale of 100,000 units per year according to the overall planning of this line. Chery plans to complete the development strategy of production, supply and marketing of 200,000 new energy technology products by this year, and promote the development plan of China's new energy vehicle industry to a greater ladder.
