The Choice of Tesla: Permanent Magnet Motor?
Neodymium Permanent Magnets for Tesla Electric Vehicles
It is reported that Tesla nowadays is purchasing large amounts of neodymium magnets for the driving motor of their electric vehicles. That is to say, Tesla is giving up traditional induction machine gradually, and using permanent magnetic direct-driving motor instead, which is the most widely used in new energy field.
Tesla has been using three-phase induction motor, specifically, the asynchronous motor for their electric vehicle for a long time, which consists of stator and rotor to form different magnetic field. This kind of motor can stand the drastically working temperature changing. And as proved, it has high efficiency and low cost. But this motor has great energy consumption, which is the key element to limit the development of electric vehicle.
Relatively, the permanent magnet motor is not only energy saving, but also light weighted with high efficiency and small size. Although it has complicated structure and comparatively higher cost, it is still well-liked in the market. And according to the experts, from the view of new energy vehicles’ demands and global economy, high efficiency, low energy consumption and long endurance ability are the most important factors currently.
The CEO of Tesla shows that they are now choosing permanent magnetic motor of EV to cater to China’s market. And they will pick 3 to 4 neodymium magnet manufactures as suppliers in China. As a matter of fact, Tesla's situation is gradually advancing after some hardships since foundation. While the ultimate goal of Tesla is not electric vehicle, instead, their dream is to promote the development of sustainable energy globally. Therefore, it is believed that the demands of neodymium magnets will be greater in the future.
