Roewe E50 drive motor listed.
2012165438+15 October, SAIC announced the official launch of its Roewe brand E50 pure electric vehicle. This model is equipped with a one-button start system for the whole vehicle, a SMART HOLD electronic handbrake and a remote real-time safety monitoring system for vehicles. It is an environmentally-friendly new energy vehicle with a strong sense of science and technology. Huayu Automobile Electrical System Co., Ltd., a new energy core component manufacturer under Huayu Automobile, has built a drive motor product for Roewe E50, which makes the whole vehicle have "domestic leading and international first-class" power performance.
"Aerospace technology, pure independent research and development, international leading" drive motor.
The birth of Roewe E50 changed the previous pattern that "power core components mainly rely on foreign technology". The acceleration time of 0-50 km/h is only 5.3 seconds, but such excellent dynamic performance is purely domestic technology. The predecessor of Huayu Automotive Electrical System Co., Ltd. is an expert team specially established for the research and development of Roewe E50 drive motor. The team was established in 2009. The team members are experts from China Aerospace Science and Industry Group's Huayu Automobile, Guizhou Aerospace and other parts companies. They have many years of experience in motor design, development and manufacture. They are committed to applying the cutting-edge technology of China's aerospace industry to new energy vehicles in China, so that China people can have their own voice in the core technology of new energy vehicles. With the ideal of * * *, in March of 20 1 1, Huayu Automotive Electrical System Co., Ltd. was formally incorporated, and was jointly invested by Huayu Automotive System Co., Ltd. and Guizhou Aerospace Industry Co., Ltd. Its main business includes research and development, production and sales of various automobile motors and their control systems.
The embedded permanent magnet synchronous motor is developed and produced for Roewe E50. Its rated power is 38kW, the measured peak power is 63kW, and the peak torque exceeds 160Nm. The rated power of the motor is 38kW /3000rpm, and the power density of the whole machine exceeds 1.6kW/kg. The measured maximum efficiency of the motor reaches 97%, and the high efficiency area (efficiency >: 90%) is greater than 85%.
In the prototype stage, the performance parameters of the driving motor are tested on the bench, and various safety parameters are checked. 20 1 1 passed the design verification test in the first half of the year, and 20 12 passed the announcement test and production verification test, including various environmental, vibration, durability and protection tests. In the process of research and development, the motor has passed the road durability test (including bad road test) at high temperature, low temperature and 6.5438+0.6 million kilometers and the whole vehicle.
The permanent magnet synchronous drive motor tailored by Huayu Automotive Electrical System Co., Ltd. will surely be an epoch-making benchmark product with world-class level and purely domestic independent research and development. Huayu Electric's next-generation drive motor products are mainly used for supporting high-end cars. The peak torque will exceed 300Nm, the peak power will be 70kW, and the motor weight will be less than 30kg. Compared with the previous generation drive motors, the new generation products have higher efficiency, higher power density, higher torque density and lower electromagnetic noise. Its prototype is currently in the manufacturing stage, and its research and development progress is the fastest in China. After multiple assessments, many indicators are advanced in China.
In addition to the "passenger car platform" series products, Huayu Electric is also actively developing the "commercial car platform" series products, among which the power density of the 100kW drive motor under research will exceed 2.5kW/kg, which is mainly used for supporting urban hybrid buses.
Automatic motor production line and perfect testing equipment ensure the consistency and reliability of products.
All motor products of Huayu Electric adopt automatic motor production line to ensure the consistency and reliability of products, including motor rotor production line, stator production line, armature production line and assembly line. The main production equipment covered are: rotor riveting machine, rotor nut locking machine, dynamic balancing machine, bearing press, rotor stator sizing sub-equipment, slot insulation molding insert machine, vertical winding machine, embedding machine, coil expanding machine, intermediate setting machine, final setting machine, single-head binding machine, armature tester, stator dripping paint roller dipping machine, stator tester, etc.
In terms of IP67 test and test equipment, Huayu Electric has several motor test benches, complete temperature performance test benches, design stage laboratories and production stage laboratories, which can cover all temperature shocks, temperature cycles, high/low temperature storage, (alternating) damp heat, chemical spraying, high temperature durability, condensation, drop and high temperature durability, including drive motors and their control systems below 125kW.
Self-developed high-performance and high-reliability power electronic equipment
Huayu Electric independently develops, designs and produces power electronic boxes (including motor controllers and DC/DC converters) relying on aerospace technology. As the control system of vehicle drive motor, the power electronic box project started to be developed in May of 20 1 1. According to the requirements of vehicle customer project nodes, the approval of tooling samples will be completed in 20 13 years, and the approval of mass production will be completed in 20 14 years. By then, the product will be one of the core components of the new energy vehicle drive system and supplied to many domestic vehicle companies.
At present, the power electronic box products have realized the basic functions of speed and torque control mode, four-quadrant operation (which can control the charging current), deep field weak magnetic control, automatic zero calibration of resolver, and the external characteristic curve meets the requirements of SAIC. At the same time, it has the characteristics of high efficiency, high torque control accuracy of 2 n m and comprehensive and reliable protection function. The DC/DC module adopts digital bidirectional switching technology.
At the same time, the power electronic box products are being tested as planned, such as vehicle test, EMC test and temperature and humidity test. Through various simulations of the professional disciplines involved in the products, the structure, hardware and software are designed and optimized with reference to the test and simulation results.
Diversified and serialized product development platform to meet the needs of different vehicle customers.
Huayu Electric's next five-year plan will focus on supporting the core components of the drive system of pure electric vehicles, medium hybrid vehicles and (plug-in) strong hybrid vehicles. The product serialization platform includes: main drive motors (52KW, 75KW, 85KW, 90KW, 100KW, 150KW, 200KW) and generators. In addition, Huayu Electric will also launch two power steering motors, 260W and 500W, which are respectively for traditional internal combustion engine vehicles and new energy vehicles.
It is estimated that by 20 17, the annual planned production capacity of the core components of the drive and control system of Huayu electric new energy vehicle will reach 750,000 units/set.
