Swedish Manufacturer Develops Electric Car Motor Weighing Only 30kg, Fits In A Backpack, Delivers Over 300hp Of Power

Koenigsegg Developed An Electric Car Motor That Can Deliver 300 Horsepower And 600 Nm Of Torque. The New Electric Motor Is Made With Aerospace-Grade Steel, Making Its Weight Only 30 Kg

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

All The Details About Koenigsegg’s Electric Motor

The Quark motor is very compact, lightweight, and also combines two layouts, as mentioned earlier. Radial flow is much more commonly used in current electric cars, while axial flow is more innovative, as produced by Mercedes-owned company Yasa.

The electric motor features a set of magnets located at its edge and another set that act on one side of the rotor. The company’s chief engineer for electric motor design, Dragos-Mihai Postariu, states that the electric motor was designed to generate strong acceleration at low speeds.

Thus, as seen in the Gemera, a hypercar capable of delivering 1,700 hp, it is possible to accelerate dramatically even when using thermal engines, where power is used for high speeds. Due to Raxial Flux technology, the chief engineer states that it was possible to accelerate from 0 to 400 km/h without energy loss and with continuous thrust.

Koenigsegg’s Electric Car Motor Uses Aerospace-Grade Steel

Aerospace-grade high-strength steels were used for the construction of the electric motor. According to the person in charge of creating the company’s electric motors, Andreas Szekely, it was necessary to reduce the weight as much as possible.

Additionally, direct cooling was also used, which is more efficient and creates a more compact layout. For the rotor, Swedish technicians decided to use Koenigsegg Aircore carbon fiber, which the company already employs in steering wheels, seats, and other components.

For some time, this material has been used by Unplugged Performance for the production of aerodynamic kits for Tesla electric cars. Andreas claims that the company has managed to develop a lighter and smaller motor than the one used in the Gemera, and believes that there are no other motors in this class that can be so small, especially to offer 600 Nm of torque and 340 hp of power.

Koenigsegg Claims Its Invention Can Be Used In Various Sectors

According to the company’s CEO, Christian von Koenigsegg, there is another advantage linked to the electric car motor. It can be used in various sectors without needing a transmission to be assembled, unlike other motors which, at certain speeds, require a gearbox that adds weight and loses efficiency. The Quark can be used with direct transmission, both in the aerospace and maritime fields.

To drive the wheels, the motor alone is not capable. Thus, the company created a complete scheme known as Terrier, which features two Quark motors and one David inverter.
