TB power motors at Nuremburg 2012

All Chinese companies are not thieves . From what I understand there are fundamental laws that allow a brushless motor to even turn .No one is reinventing the wheel lets be serious. Specifications of materials and construction are the variables. Anyone can make a motor seriously. There are tonnes of books on the subject. For me its which company with provide me what I am looking for within my budget . It wouldn't make sense to make a square motor to fit any of my cars . Motors will be round , Will have rotors , will have laminations if its 4 pole and sometimes will even have a color on them . And from what castle tells me even the good magnets come from china .

god invented it, the usa and japan figured out how to utilize it, the chinese figured out how to make people produce them for cheap. Win Win right, like the Chinese not calling in our 4 trillion debt to them so our dollar goes to nothing and we cant pay the wealthy there to continue to make the poor produce stuff for cheap. Sound like where were headed ?

the homepage of tp power doesn't work, unfortunately. I have seen these motors on KD, and I am waiting for some detail pics.

Regarding neodym, it's sources are mainly found in China. so they aren't stealing nothing from somebody else. Probably other countries are jealous... what they did in the last year was, that they have increased the prices for neodym dramatically. But I guess 90 % of all Neodym is found in China. And about all BL-Motors have their Neodym. Still, there are a few manufacturers for that metal, and there are quite a lot of differend blends. from strong but not very stable reg. heat to less strong, but robust reg. heat, and so on. Need some rare earth magnets?

As most of the metal is found in china, Bosch has already a new Motor in progress, which is working without neodym. Like that, future electric cars are independend of that metal.
Also Lithium does mainly come from China, and most manufacturer of Lithium-Cells are found in China, further in Taiwan, US (A123, they are in Asia, too) and Canada (Molicell).

who will by one of these motors?
