A new generation of E-motors

The all-new Quark e-motor relooks the fundamentals of magnetism, materials, cooling, and packaging instead of following industry standards. This inspired its name since the Quark is the only elementary particle to experience all four fundamental forces (electromagnetism, gravitation, strong interaction, and weak interaction). Given how it also relates to the mystery of magnetism, the name Quark rendered itself well for this novel e-motor design.

Traditionally, e-motors were either axial flux solutions (more torque-dense and less power-dense) or radial flux solutions (more power-dense and less torque-rich). However, Koenigsegg did not want to lean heavily on either, so they engineered an industry-first mix of the two topologies named Raxial Flux. The result is an e-motor with the best torque-to-power-to-weight ratio in the industry.




Application in the Koenigsegg Gemera

The Quark is designed to bolster the low-speed range of the Gemera, where you need it, for brutal acceleration. The ICE then focuses on the high-speed range. What this means in terms of performance for the Gemera is a big power surge followed by a continuous record-speed push to 400 km/h without any torque or power losses.




Unique design and engineering

The Quark is constructed out of 300M steel, which is most commonly used in motorsports and the aerospace industry. Direct cooling was chosen for its higher cooling efficiency and compact design, while the rotor uses the renowned Koenigsegg Aircore™ hollow carbon fiber technology (presently used in Koenigsegg’s rims, steering wheel, seats, etc). This overcame the challenges of the Gemera’s powertrain requirements but also exceeded the goals of making it lighter and smaller than any electric motors in this class. The Quark presents new benchmarks in compact and torque-rich engineering with the first production version weighing just 30 kg, producing up to 600 Nm of torque and 250 kW of power. Without the extra driveline functions for the Gemera, the Quark can drop below 28.5 kg in weight.

For many applications

The Quark is unique in its high efficiency in combination with its class-leading torque-to-power-to-rpm-to-weight matrix. This means, when using the Quark in applications such as marine, aircraft or VTOL, there is no need for a step-down transmission, instead direct drive can be achieved, as the RPM of the motor is right from the get-go. Small, high-revving motors can have higher peak power to weight ratio, but they need transmissions in most applications in order to get to the desired output rpm and torque, causing energy loss and adding weight and complexity to do the same job. So any benefit in size is lost. 

The Quark is a part of Koenigsegg’s ground-up, in-house developed complete HV (high voltage) architecture which includes, but is not limited to, e-motors, batteries and controllers.
