Tesla’s Roadster Motor Technology

Tesla Motors was founded in 2003 and is an American automotive and energy storage company. This article will focus on how Tesla's Roadster electric motor works. The basics of the car are pretty standard and straightforward, but the intricate details are much more intriguing. It will also detail the key differences between an internal combustion engine and Tesla's electric motor. At just about the size of a watermelon, the motor converts electricity into mechanical power and also acts as a generator, turning mechanical power into electricity.
