Elon Musk Unveils New Tesla Motor That Promises to Be Not Only a Revolution in the Electric Car Market But Also to Combustion Engines from Manufacturers Like Toyota.
Elon Musk is just steps away from taking the electric car market to another level with the launch of a new Tesla motor called Hairpin, which promises to change the game against Toyota and other manufacturers. The billionaire recently revealed this revolutionary drive unit that makes electric vehicles even more competitive not only against previous generations but also in comparison to combustion vehicles.
Main Differentiators of Tesla’s New Motor
When it comes to Tesla, under Elon Musk’s leadership, it can be said that there are many admirers and critics; however, it cannot be denied that the company is making significant advances in the electric world. Focused on reducing costs and improving the environment, Tesla is using software to model the best configuration and a unique design that involves welding without the use of rare earth minerals.
This has resulted in a powertrain composed of a US$ 1,000 motor and a US$ 5,000 battery, making its mass-market vehicle not only viable but also with a high gross margin.

What is truly surprising is Tesla’s new motor, which promises to leave Toyota behind. The new Hairpin motors are something entirely innovative with a more compact, lighter, and more advanced design.
One of the main features of this new Tesla motor is its filling factor, which can reach 0.7, compared to the 0.4 found in traditional round wires. This means that Elon Musk’s motor exhibits better thermal performance and allows for a fully automated production process.
Tesla Changes Layout to Utilize Its New Motor
The new inverter design is revolutionary, as it is much more compact with a fused high-voltage connector and a data connector. By removing the fused cover, you can see this for yourself.
To leave Toyota behind, Elon Musk’s Tesla has optimized the layout of the new motor and improved the cooling assembly. A friction-welded piece was used to join them. The motor filter is no longer user-replaceable, but this is because it does not need to be changed throughout the vehicle’s lifespan.
Unlike a combustion engine, this filter serves only to prevent the accumulation of small wear particles and manufacturing debris, thus it never needs to be replaced. Elon Musk’s new Tesla motor has clips for stator winding instead of round wires.
The rectangular geometry of these clips enables better space utilization, generating a better filling factor, meaning that copper winding more effectively uses the available space, generating 20% more efficiency.
Advantages of the New Motor Compared to Toyota’s and Other Manufacturers’
This technology from Elon Musk represents a series of advantages. For instance, the higher filling factor generates a more intense magnetic field, resulting in a more powerful rotor rotation and greater torque at the wheels.
Due to the stator being smaller, energy losses during the passage of electric current through the copper, known as copper losses, are minimal.
The optimized winding path simplifies the assembly process, and Tesla’s new motor, which promises to surpass Toyota, presents a lower risk of long-term failures. Its clips can conduct more current than round wires, resulting in less heat in the winding and the motor.
