Quark and Terrier, Koenigsegg’s Preset Their First E-Motor and E-Drive Units – ‘Roxial Flux’ topology

 ‘Roxial Flux’ topology is  an axial flux motor (also known as an axial gap motor, or pancake motor) is a geometry of electric motor construction where the gap between the rotor and stator, and as such the heading of engaging advancement between the two, is changed contrasting with the focal point of turn, rather than radially in like way with the concentric barrel shaped assessment of the more common winding opening engine.

  Koenigsegg continues to offer advanced component offerings for its internal technology development and marketing.  It started with the recently introduced revolutionary 6-stage inverter David – and now uses the novel torque / energy-rich balance between the company’s new invention, the quark electric motor radial (axial) and axial (torque).  -Temperature) The flux topology is called the Roxial Flux.  In addition, Koenigsegg has combined two quark e-motors with a David inverter, as well as planetary gear sets to create a class-leading terrier, a torque vectoring EV-drive unit.

  Quark Electric Motor with Novel Roxial Flux Topology

  A key driver for the development of the Quark e-motor is to continue the company’s record-breaking heritage with the Koenigsegg Gemera;  EV is offering the broad market the opportunity to tap torque-rich, ultra-compact e-motor for a wide range of applications such as powertrains, aerospace, VTOL, marine and more.

  Quark E-Motor follows the standards of magnetism, materials, cooling and packaging rather than the basics, hence its name.  The quark primary particle is the only particle that experiences all four fundamental forces (electromagnetism, gravity, strong interaction and weak interaction).  Considering how it relates to the mystery of magnetism, the name Quark is well represented in the new e-motor design.

  The radial and axial flux layout mix enables the best torque to power and weight ratio in the industry.  Leading this development, Electric Motor Design Lead Dragos-Mihai Posteri, commented: “Quark is designed to increase the low-speed range of the Jemera, if you need it, for brutal acceleration. ICE then focuses on high-speed range.  A major energy surge after a continuous record-speed push to 400 km / h without power loss.

Koenigsegg’s latest internal innovation,

  E-Motor Development Lead Andras Szekely describes how Koenigsegg encountered the weight penalty: “We built the shaft inside the quark from 300M steel used in motorsports and aerospace.  Direct Cooling has been selected for its high cooling efficiency and compact design.  The rotor also uses the renowned Koenigsegg Aircore hollow carbon fiber technology (currently used in Koenigsegg’s rims, steering wheel, seats, etc.).  Not only have we overcome the challenge of the powertrain requirements of the Jemera, but we have exceeded the goals of making it lighter and smaller than any other electric motors in this class. 

Quark presents new standards in compact and torque-rich engineering, the first production version weighing just 30kg, producing 600 Nm of torque and 250 kW of power.  With no additional driveline functionality for the Gemera, Quark can drop below 28.5 kg in weight.

Quark is extraordinary in its high convenience in mix in with its get-together primary purpose to-control to-rpm-to-weight framework. Small high-revving motors can have a maximum power to weight ratio, but they require transmissions in most applications to get the desired output RPM and torque, causing energy loss and adding weight and complexity to do the same thing. In different cases, as a terrier application, transmissions can be lessened in size and intricacy showed up contrastingly according to high-firing up, low-power thick engines, which is a critical accomplishment. She adds.

  The launch of the Quark e-motor parallel to the recently unveiled David Inverter allowed Koenigsegg to create one of the most exciting EV-drive units, ideal for many EV applications – The Terrier.  The two-quark-one-David configuration has provided the opportunity to create the most energy / torque dense, torque vectoring drive unit in the EV industry.

  In traditional Koenigsegg style, the drive unit is named Terrier –  the drive unit are characterized by their small, energetic and intrepid behavior.

    David’s 6-phase offers 3 steps per quark, so that the terrier can outperform today’s drive units by drastically reducing the weight, size, and components, requiring only one inverter (instead of two). 

Furthermore, given the quark’s flat packaging, David can squarely slot between two quarks to create a square super-dense package.  Finally, since quarks provide huge power and torque at reasonable RPMs, only small low-ratio highly efficient planetary gear sets are required at each output.

  The compact and unique packaging allows the terrier to elasto-bolt directly to the monocoque or chassis – thus design, engineering and luxury amenities are not possible in the past.  This feature potentially reduces the complexity of additional subframes or weights.

Quark is extraordinary in its high ampleness in blend in with its get-together primary purpose to-control to-rpm-to-weight association,  This means that when using Quark in applications like Ocean, Aeroplane or VTOL, no need for a step-down transmission, but rather a direct drive can be achieved, since the motor’s RPM is correct from the get-go. 

Smaller high-revving motors can have a maximum power to weight ratio, but they require transmissions in most applications to get the desired output rpm and torque, causing energy loss and adding weight and complexity to do the same thing.  So any advantage in size is lost.  

  In different cases, as a terrier implementation, transmissions can be diminished in size and multi-layered plan veered from high-firing up, low-power thick engines, which is a huge achievement, venturing to appear at the edge of the best distance.
