Project Of Rare Earth Permanent Magne Generators For Cars Feasibility Study

Afte joining the WTO, the world's leading auto parts companies have also entered the Chinese joint ventures or wholly-owned production. As the car is a vehicle power system generator in important supporting parts, a car key and indispensable component of its excellent performance is an important indicator of advanced automotive technology, one of the motor vehicle is so highly competitive market, one of key products . Motor vehicle products from traditional products is bound to be better toward the functionality, performance and more reliable, longer life, smaller, lighter weight, greater than power, new materials, new technology more widely used, the direction of higher-tech development.Currently, the domestic automobile generator mostly rectifier generator, this generator there are shortcomings: First, install the rotor field winding, corresponding with a carbon brush, slip ring, so that the motor size, high failure rate, life is short; the second is by adjusting the field winding of the current regulator to achieve the corresponding arc energy to produce the excitation winding, magnitude and angle matching the complex structure of the voltage regulator, power consumption. Generating domestic car now mostly ferrite permanent magnet generator, the generator also has significant disadvantages: remanent flux density ferrite magnet material is not high, although higher than the power than conventional generators, but still significantly lower in rare earth permanent magnet generator. FAW Liaoyuan Automobile Electrical Co., Ltd. (hereinafter referred to as Liaoyuan steam and electricity companies) adopt cooperation with institutions of higher education research and development approach, take the introduction of absorption and self-development and innovation of combining road, keeping the pace of replacement of the product market, and supporting the development of car technology to meet the requirements, thereby enhancing the competitiveness of enterprises. To this end, Liaoyuan Automobile Power Company jointly with Harbin Institute of Technology, after years of research and development, to achieve breakthrough results, by the successful development of rare earth permanent magnet generator. The new product was awarded first prize for outstanding new products in Jilin Province, Jilin Province Economic Committee by the organization of production new products and technologies identified, the National Automobile Quality Supervision and Inspection and Testing Center of FAW Car Co. trial. In this paper, demonstration and feasibility studies, the product has been completely replace imported, to the full realization of the requirements of domestic motor cars, and can compete in international markets.
