In order to build a car, Apple frantically digs Tesla.

On April 22nd, according to foreign media reports, the US Patent and Trademark Office published a patent showing that Apple is studying a three-phase AC induction motor for "Apple Car", which is similar to Tesla's squirrel cage motor technology. Despite the submission of legally required documents and patents, Apple has not confirmed whether it is doing vehicle research and development.

The patent number of this patent is 163127, and it is called "Motor with bar-wound stator and end cooling". Apple may choose this technology because it is relatively low in manufacturing cost, useful on rugged terrain, and can produce high starting torque when the voltage/frequency is controlled. If properly controlled, the efficiency of this motor can reach 9%. Compared with permanent magnet drives, this motor is expected to have a longer life and require less maintenance.

In fact, in 218, it was revealed that Apple will lock in the "next star product"-Apple Auto, which will revolutionize the auto market like the iPhone in 27.

Guo Ming, an analyst with Tianfeng International Securities, who is known as "the Oracle of Apple", predicted that Apple would launch Apple cars between 223 and 225, and AR glasses in 22.

In a research report, Guo Ming predicted how Apple will create a market value of 2 trillion US dollars. "Services, AR (augmented reality) and Apple cars will create the next trillion US dollars market value for Apple."

Guo Ming said in the above report that the current automobile market has a "huge demand for replacement" because the industry is in the process of being redefined by new technologies. Apple's advanced technology will redefine the car and "make Apple cars different from other products".

Guo Ming also believes that Apple is "better at integrating hardware, software and services", which can surpass other competitors in the current consumer electronics field and potential automobile field. After the release of Apple Auto, Apple's service business will also grow significantly as the company enters the "huge auto finance market".

In August last year, it was reported by the American technology blog Daring Fireball that Doug Field, a former Tesla executive, would join Apple's "Project Titan" in developing cars. Before joining Tesla in 213, Field was Apple's vice president in charge of hardware. This joining means that he has returned to Apple.

It is understood that Doug Field joined Tesla in 213 to help develop new electric vehicles. In 217, he was appointed to be in charge of the production and manufacturing departments of Model 3 at the same time. However, due to the over-automation of the production line, the production lagged behind. In April, Musk took the initiative to intervene in the production line. At this time, Field's responsibilities have been unloaded a lot. In July, Doug Field officially chose to leave Tesla.

Subsequently, CNBC, an American financial website, made an in-depth analysis of the "poaching war" between Apple and Tesla. The website reported that according to LinkedIn, a social networking site in the workplace, about 46 Tesla employees jumped ship to Apple last year.

It is worth noting that not all employees hired from Tesla participated in the Titan car project, and many people also developed display, optics and battery technology for Apple.

This year, Apple also hired employees from Tesla for positions such as Autopilot Autopilot System, Quality Assurance (QA), Powertrain System, Mechanical Design and Firmware Engineer, and several global supply chain managers. Some employees jumped directly from Tesla to Apple, while others were fired or dismissed by Tesla before joining Apple.
