According to Electric Home, on July 31, Tesla issued a message to celebrate the rollout of the world's 10 millionth electric drive system, which is Tesla's first "10 million" milestone moment. It is reported that the world's 10 millionth electric drive system rolled off the production line at Tesla's Shanghai Super Factory in July.

Tesla's electric drive systems are all developed and produced by Tesla from scratch. Data shows that Tesla can roll off an electric drive system every five seconds worldwide. Tesla has redefined the electric drive system. Each electric drive system integrates three major parts: motor, gearbox, and motor controller. It is efficient and economical. It is the powerful heart of Tesla electric vehicles and the key component that brings the iconic "Tesla power" to each car.

The electric drive system is one of the core systems of electric vehicles, mainly composed of drive motors, motor controllers and speed reducers (variators). Tesla's electric drive system has gone through four generations of technology iterations:

• The first generation of electric drive systems was used in Roadster（parameter丨picture), authorized by AC Propulsion to use asynchronous induction motors as drive motors. The controller uses IGBT single-tube parallel technology. It was developed the earliest and delivered in small quantities, so it is little known to the world.

• The second generation electric drive system is used in Model S / X, the controller is changed to a three-dimensional structure, similar to a laminated sandwich structure, with the asynchronous motor and controller arranged symmetrically on the left and right.

• The third generation electric drive system is used in Model 3 / Y, for the first time, is equipped with a permanent magnet synchronous motor, uses silicon carbide power devices in the controller, and changes the structural design of the controller, making it more compact overall.

• The fourth-generation electric drive system optimizes the protection of the output three-phase electrical connections and adds an infrared temperature sensor; the connector positions on the controller that were previously fixed with screws are now replaced with an one-piece molding process using stirring welding, further reducing costs; the motor oil filter housing is integrally cast, and the filter element is built-in and is no longer replaceable, etc.
