Langfang Yongtai Electric Vehicle Motor Co., Ltd.   

Langfang Yongtai electric motor Co., Ltd is a high-tech enterprise for many years specializing in the production of electric vehicle motor, are subject to the production of a variety of motor industry acclaim and extensive application. In recent years also invested heavily in the industry, tissue engineers and experienced senior technicians and experts act with united strength, joint research, after a lot of test and continuous improvement, and finally find out the leading technology new, unique world electric vehicle motor, so that a plurality of parameters of power, electric machine, the load torque, efficiency speed is optimized, and the realization of automatic program control. Through the test and failure of a hundred times, finally successfully developed the world's first "YT electronic programming type external rotor hub motor" and "YT electronic programming type internal rotor motor, mechanical and electrical integration" has successfully solved the technical problems of world motor dynamics for many years, is the core product development of electric vehicle industry of the world. The development of this motor technology success is the technology reform of the world motor dynamics, our company has this technology applied to a number of national patents, after several experts in national patent bureau were reviewed and the seizure of a full range of rated recognized, so that my company has its own core technology, intellectual property and high tech products

The safety car is the route one must take to realize the sustainable development of the transportation, wherein, the electric car with its in the process of using ultra low emission / zero emissions, energy utilization technology advantage of diversification and high efficiency of the highly valued, accelerate. In the electric car industry a lot of electric drive system, with outer rotor and the inner rotor hub motor electromechanical integrated motor system as power is the world's electric field of research focus and study. In recent years, much of the World Motor Research Institute, universities, motor manufacturers and Canadian famous motor manufacturers TM4, Wavecrcst and other countries USA motor industry has been invested heavily in research, because the wheels and body interior space constraints, the electric car high requirements for motor power density of motor performance, anti vibration and noise requirements. Harsh, therefore failed to various technical problems rotor hub motor and mechanical and electrical integration to solve the inner rotor motor. Advantages of outer rotor hub motor and the inner rotor motor is mechanical and electrical integration: save energy, can control the torque in a wide speed range, can be completely omitted transmission device, the overall efficiency of the motor is improved greatly, the arrangement of the degrees of freedom of the space inside the car is greatly improved. Now the world is mostly used in rotor of high speed motor as power electric automobile, need and the gear box, drive shaft, differential, rear axle is connected with the driving, occupies too much body space, great influence on the vehicle's overall layout effect, so the electric vehicle drive technology can only stay in the last century 90's..
