2021. Elon Musk announced at the 2021 Shareholder Meeting, Oct 7, 2021, that Tesla hoped to increase the production capacity at the Fremont Factory by 50% in the next couple of years. Tesla Model S manufacturing process Overview The manufacturing process uses more than 160 specialist robots, including 10 of the largest robots in the world, which are named after X-Men characters. Many of the Model S's unique components, including the battery pack, battery module, and drive units are manufactured in-house. The plant has a high level of integration compared with other modern car assembly plants, with most processes taking place within the Tesla Factory. This includes most of the stamping and machining, painting, and some coding. The hydraulic press lines used to stamp 5,000 body panels per day with a force of 10,000 tonnes, are the largest in North America and the 6th largest in the world. Around 60% of the car parts are sourced from North America, while Japan is the second-biggest source of components . Design engineers also work at the factory itself, rather than a separate facility. Individual vehicles take between three and five days to complete the assembly process. The assembly line moves at a speed of 5 cm/s. Tesla prefers delivery by train rather than by truck, as costs and damages are less. Drive unit construction Motor construction The alternating current Induction motor is constructed in-house. The main components of the motor are the stator and rotor. The motor construction begins when a robot unspools and winds over of copper wire per motor. It then pulls the copper wire into a stack. The motor has three phases and so requires three coils of copper. A worker then lengthens and straightens each bundle of wire and inserts a hydraulic lift to transfer the motor to the next station. A worker insulates each bundle of copper wire in a plastic sleeve to prevent the bundles from touching one another. The ends of the bundles are then snipped to the correct length. Lugs are added and crimped to form attachment points for the motor's three phases. A specialized automatic sewing machine then binds the coils together to keep them in place, the increased tightness of the binding provided by a robotic sewing machine increases the efficiency of the motor. The stator is then encased in a two part epoxy resin to help in evenly distributing the motor's
