Tesla’s ‘rotor geometry’ patent hints at more efficient electric motors
Tesla has invented a technique for increasing its all-electric vehicles’ power and torque by simply adjusting the shape of some of its electric motor’s components.
A recently published US patent application titled “Geometry of Rotor End Ring and Stator End Turns” describes how Tesla accomplishes this. According to the application, certain internal parts of an electric motor can be modified to reduce power losses from leaks in the magnetic field that effectively make the motor smaller.
The primary components of electric motors – the rotor and the stator – together generate the motion used to operate a vehicle. Simply, a magnetic field produced by electricity running through copper wires in the stator cause the magnetized bars of the rotor to spin. However, when the motor is operating at high speed, some of the electromagnetic force is lost, reducing the motor’s power.
Tesla has identified two places where this loss can be reduced – the end parts of the stator and rotor. The copper wiring in these parts is wrapped around cutout shapes, and after some testing, Tesla’s engineers learned that different shapes give different results. Per the application, “geometries for rotor end ring and stator end turns can be chosen in a way that improves performance or other characteristics of the motor.”
Overall, electric current flow becomes concentrated in different spots on the motor depending on the ‘geometry’ of these parts, thus an opportunity to limit any losses has presented itself by controlling where the concentrations happen. Tesla has filed this application to protect the process (‘method’) of building a motor with the geometry knowledge made part of the design and testing.
The process is described in the application’s Abstract as follows:
“A method of making an AC induction motor includes: providing a rotor and a stator for the AC induction motor; determining, for different geometries of an end ring of the rotor, a location of a first centroid of current density in the end ring; determining, for end turns of the stator, a location of a second centroid of current density in the end turns; selecting a geometry for at least the endring of the rotor so that an axial distance between the first centroid of current density and the second centroid of current density is minimized; and assembling the AC induction motor, wherein the end turns and the end ring have the selected geometries.”
Although the publication was only recently available to the public, this application is related to another patent that was filed in 2015, meaning that Tesla is likely already implementing the findings and invention into their manufacturing process. This is rather unsurprising considering the company’s tendency to constantly improve its vehicles’ components as soon as the upgrades are available. Elon Musk himself has mentioned this on Twitter, stating that Tesla’s electric cars are “partially upgraded every month as soon as a new subsystem is ready for production.” This was also highlighted by President of Automotive Jerome Guillen last December, when he highlighted that the designs of Tesla’s batteries are always evolving.
Automotive teardown expert Sandy Munro concluded following a thorough analysis of an early-production Model 3 that the vehicle’s electric motors are among the best in the industry today. In an appearance at YouTube’s Autoline TV, Munro noted that the Model 3’s electric motors are more efficient and more cost-effective than the motors found in the Chevy Bolt EV and the BMW i3. “They’ve got magic. The electric motor is smaller and lighter than everybody else, but outperforms everybody,” Munro said.

A new report claims that Apple is in the process of developing what would be the missing link for Tesla to get CarPlay.
Apple and Tesla have been reportedly working together for some time to give Tesla owners the opportunity to utilize CarPlay within their vehicles. While many owners are more than happy with Tesla’s in-house UI, which is seamless, effective, and smooth, some still want CarPlay, which does have its advantages.
A report from 9to5Mac now states that a new CarPlay technology that was highlighted during the Worldwide Developers Conference (WWDC) would potentially be the bridge between Tesla and Apple. With the addition of a feature known as “Route Sharing,” which gives a navigation app the ability to share routing data with the vehicle, Tesla would be able to launch CarPlay in its vehicles, the report states.
CarPlay has not been a priority for Tesla because it has done extremely well with its in-house UI, but some drivers are just used to it. Additionally, it could improve Tesla’s subpar Navigation or offer improved app capabilities, especially with iMessage.
Route Sharing is an intended addition to CarPlay’s iteration in iOS 26.4, which was released in March:
The addition of CarPlay would undoubtedly be welcome, but at the same time, it seems like Tesla realizes it is not of the utmost priority. There are so many things that Tesla is working on currently within its own vehicles, especially attempting to solve self-driving.
Back in February, Bloomberg had reported that Tesla was still working on bringing CarPlay to its vehicles, but it had not due to app compatibility issues and incredibly low adoption rates of iOS 26.
This bottleneck could buy Tesla the proper amount of time to develop CarPlay for its vehicles. It would be a welcome addition, and could be brought on with either the Summer or Fall 2026 Software Updates.
Tesla deliveries got a big boost in expectations from Wall Street firm Goldman Sachs, who believes the company will report some stronger-than-expected numbers when the second quarter comes to an end in the coming weeks.
Goldman Sachs has raised its vehicle delivery forecast for Tesla (NASDAQ: TSLA) in the second quarter of 2026, signaling growing confidence in the electric vehicle leader’s near-term momentum despite mixed market signals. Analyst Mark Delaney lifted the bank’s Q2 estimate to 420,000 units from a previous 405,000, surpassing the Visible Alpha consensus estimate of 400,000.
The upward revision stems from stronger-than-expected sales data across key regions. Europe stands out with projected year-over-year growth of 85-90 percent, driven by robust demand for Tesla’s Model Y and refreshed offerings. China posted high single-digit gains, while markets like South Korea and Australia also contributed positive momentum. These gains help offset mid-teens declines in U.S. deliveries through May, where broader EV market headwinds and competition persist.
Goldman extended its optimism to the full year, increasing its 2026 delivery projection to 1.73 million vehicles from 1.72 million. Longer-term forecasts remain unchanged, with 1.88 million units expected in 2027 and 1.96 million in 2028. The bank also nudged its 2026 earnings-per-share estimate higher to $1.35 from $1.30, reflecting anticipated margin benefits from higher volumes and operational efficiencies.
Despite these positive adjustments, Goldman maintained its Neutral rating and $375 price target on Tesla shares. At current trading levels near $411, the stock sits about 8-9 percent above the target, highlighting ongoing valuation concerns even as delivery momentum builds. Tesla’s Q1 2026 deliveries totaled 358,023 units, setting a baseline for recovery expectations in the current period.
This update arrives as Tesla prepares to report official Q2 figures shortly after June 30. Investors and analysts will closely watch not only headline delivery numbers but also regional breakdowns, average selling prices, and progress on energy storage deployments and autonomous technology initiatives.
The move by Goldman Sachs underscores a broader narrative for Tesla: while legacy auto markets face softening demand and tariff uncertainties, Tesla’s global footprint and product pipeline provide resilience. Europe’s surge reflects pent-up demand and policy support for EVs, while China’s steady growth highlights Tesla’s competitive positioning against local rivals.
Tesla still has its work cut out for it, including U.S. price sensitivity and intensifying competition. Yet Goldman’s revision adds to a series of analyst notes suggesting Q2 could mark a turning point. As Tesla pushes toward higher production rates at facilities in Fremont, Shanghai, and Berlin, sustained execution will be key to validating these higher forecasts.
We have said numerous times that deliveries are becoming a less important metric in the grand scheme of things, as AI truly takes precedence in the company’s thesis.
For Tesla bulls, the Goldman note reinforces faith in underlying demand trends. For skeptics, the unchanged rating serves as a reminder that delivery beats alone may not immediately resolve valuation debates in a high-interest-rate environment. Tesla’s stock reaction will likely hinge on the official numbers and management commentary in the coming weeks.
