Koenigsegg has developed an engine for electric cars that can deliver 300 horsepower and 600 Nm of torque. The new electric motor is made from aerospace steel, making it weigh just 30 kg.

Also focusing on the transition from electric cars, Swedish company Koenigsegg, which recently unveiled a six-phase inverter named after David, has now launched its first electric motor for zero-emission models. The engine was named Quark and offers very high levels of torque and power, as is usually required by cars produced by the Swedish manufacturer. The motor for electric cars uses an architecture that combines the benefits of an axial motor, which delivers more torque, and a radial motor, which provides greater power. Due to this dual structure, the technology is being called Raxial Flow, which comes from the union of the two names.

All details about Koenigsegg electric motor

The Quark engine is very compact, lightweight, and even combines two layouts, as mentioned earlier. Radial flow is much more widely used in today's electric cars and axial flow is more innovative, such as that produced by Mercedes-owned company Yasa.

The electric motor has a set of magnets that are on its edge and another set that act on one side of the rotor. The chief engineer of the Swedish company for the design of electric motors, Dragos-Mihai Postariu, says that the electric motor was developed thinking about generating a strong impulse at low speeds.

Therefore, as in the Gemera, a hypercar capable of delivering 1.700 hp, it is possible to accelerate brutally even when using thermal engines, where the power is used for high speeds. Due to the Raxial Flux technology, the chief engineer claims that it was possible to accelerate from 0 to 400 km/h without loss of energy and with continuous boost.

Koenigsegg electric car engine uses aerospace steel

For the construction of the electric motor, high strength steels from the aerospace industry were used. According to the person responsible for creating the company's electric motors, Andreas Szekely, it was necessary to reduce the weight as much as possible.

In addition, direct cooling was also used, which is more efficient and generates a more compact layout. For the rotor, the Swedish technicians decided to use Koenigsegg Aircore carbon fiber, which the company already uses in the steering wheel, seats and other components.

For some time, this material has been used by Unlpugged Performance for the production of aerodynamic kits for Tesla electric cars. Andreas says that the company managed to develop a lighter and smaller engine than the one used in the Gemera, and believes that there are no other engines in this class that can be so small, even more so to be able to offer 600 Nm of Torque and 340 hp of power.

Koenigsegg claims that his invention can be used in several sectors

According to the company's CEO, Christian von Koenigsegg, there is another advantage linked to the engine for electric cars. It can be used in several sectors without a transmission being mounted, thus being different from other engines that, for certain speeds, require a gearbox, adding weight and losing efficiency. Quark can be used with direct transmission, both in the aeronautical and marine fields.

To move the wheels, the engine alone is not capable. Therefore, the company created a complete scheme, known as a Terrier, which has two Quark motors and a David inverter.
