New Hybrid Technology Using Axial Flux Motor
It looks like Porsche has filed another patent.
The patent application, in simple terms, describes a structure that incorporates a thin motor between the engine and transmission, achieving both high torque density and excellent cooling performance without increasing the length of the drivetrain, even in a hybrid configuration.
The system is characterized by the placement of an axial flux motor between the internal combustion engine and the transmission.
An axial flux motor is a very thin, disk-shaped motor that is directly connected to both the engine output shaft and the transmission input shaft, with the two rotating together on the same axis.
Furthermore, this motor has a unique cooling structure that is designed so that coolant flows directly through the stator part, and the cooling space is cup-shaped so that fluid also circulates in the ring part around the outer periphery of the motor.
This allows for efficient dissipation of heat not only from the stator, which generates a lot of heat, but also from the area around the rotor.
A dual-mass flywheel is installed between the motor and engine to absorb vibrations from the engine (reducing the load on the motor bearings and increasing durability).
This structure also appears to be intended for use in combination with PDK.
So, what is different about this patent from the T-Hybrid that appeared in the 992.2 model of the Porsche 911? The motor position and mechanism in this patent appear to be completely different.
The T-Hybrid is a performance-assisted hybrid that integrates a motor into the PDK and combines it with an electric turbo to improve response during acceleration, whereas this patent seems to be a structure that incorporates a thin motor directly onto the axis of the engine and transmission to electrify the drive itself?
...But my head is already way behind it (lol) and I don't want to write something wrong, so if you're interested, please check out the patent application here (in German):DE102024123642 - Hybridantriebssystem eines Kraftfahrzeugs mit Axialflussmaschine
Some overseas media have commented on this technology, saying, "Isn't this thin motor structure ideal for high-revving naturally aspirated engines like the GT3?"
This method allows the motor to supplement torque without adding a turbo, making it possible to electrify the car while maintaining the GT3 character.
I see... but then I thought, wait, no, no, no, the GT3 (or GT3RS) doesn't need to be made into a hybrid yet, right?
※Note※
Just because a patent has been filed does not necessarily mean that it will be applied to future models.

I'm Rika, the author of this article. Since I got my hands on a Porsche 911, I've been completely hooked on Porsches and I can't stop loving them, so I started this blog. My favorite cars are the 911 Carrera (2/991), 911 Carrera Cabriolet & 911 Carrera T (1/992), GT3 (1/997) and 718 Cayman GT4 RS.
