CITAZIONE
Motor
The motor for a high-performance electric car requires a device that is simultaneously light, compact, and high in efficiency. The Tesla Roadster EV motor is just that. We accomplish this by starting with a well-optimized electromagnetic design and then using the lowest loss conductors and the highest quality magnetic steel possible.
The power of the motor is not only limited by how much power you put into it, but also by how fast it can be cooled, how hot it can operate, and how efficiently it runs. We addressed each of these in innovative ways. Our motor can operate continuously around 120°C, thanks to the array of air-cooling fins on our aluminum housing.
Without proper efficiency, our motor would convert electrical energy into heat instead of rotational energy. That’s why we constructed it with specially designed, high-quality lamination steel that has very low eddy current losses, particularly at high rpm. The rotor is made with a proprietary process that produces a low resistance “squirrel cage” with large end rings using oxygen free copper. This allows the rotor to develop high current flows, and torque, with low resistance losses. The use of a small air gap allows tight inductive coupling which, combined with low loss magnetic materials, enables the development of high torque at high rpm. Together, these factors allow us to induce large currents, even at high rpm, producing much flatter power and efficiency curves from approximately 2,000 rpm to 12,000 rpm.
The sum of all these features is a single motor with efficiencies of 85 to 95 percent, power output of up to 185 kW, and a small footprint that measures just 250 mm (diameter) by 350 mm (length).
L'utilizzo del termine "Tesla" in quell'auto e' una banale questione di marketing
difatti hanno gia' creato l'alone di parla parla che rappresenta pubblicita' a gratis
e una mezza mitizzazione
L'Auto del genio Nikola Tesla e' tutta una altra cosa 
e ti ripeto, il libro di lindermann sull'evento radiante, se ne sara' parlato 10000 volte, leggilo
