12/8/2022 0 Comments Axial flux motor![]() ![]() The flux loop starts at a magnet on the rotor and passes through the air gap between rotor and stator. ![]() To balance the magnetic forces, two rotors are often usedone on either side of the stator. It is very far from the stage in which only minor improvements happen, as we currently see with internal combustion engines. An axial flux motor places the permanent magnets on the face of the rotor, and puts the stator in front of the rotor. What makes the Quark unique is that it was designed “to take maximum profit of the radial flux in an axial-flux motor.”Īgain, that shows how the electric car is a work in process. With this simple measure, the Swedish company managed not only to diminish leakage, but used “this radial flux to augment the main axial flux.” Koenigsegg argues that it may not have invented the idea, only that it has not seen it in use before. Koenigsegg managed to achieve this simply by “ increasing rotor diameter against the bulk of the stator and optimizing the stator OD (outer diameter) to be able to accept this extra flux.” Yes, it is that simple. While the Quark offers less torque than the YASA 750, it is almost 20% lighter and way more powerful. Axial Flux Motor Magnets are usually divided into Axial flux motor magnet with skewed fan shape and Laminated type axial flux motor magnet. Building on YASAs IP, Evolito is enabling the aerospace industry to leave behind the legacy radial electric motor. Each YASA 750 weighs 37 kilograms (81.6 pounds) and delivers 800 Nm (590 pound-feet) and 180 kW (241.4 hp), while the YASA 400 weighs 28.2 kg (62.2 lb), provides 350 Nm (258.2 lb-ft) and 160 kW (214.6 hp). Axial Flux Motor is a type of electric motor that converts the energy of the motor into mechanical energy. Axial-flux: a revolutionary new approach. Innovative powertrain solutions Integrating a YASA Axial Flux motor into an electric or hybrid powertrain optimises vehicle range, performance and cost. To give you a proper basis of comparison, the Koenigsegg Regera uses three electric YASA axial motors: two YASA 750 on the rear axle and a YASA 400 on the front axle. Our axial-flux motors are fundamentally more efficient, more powerful and smaller than legacy radial motors Find out more about YASA Axial Flux Technology. The fact that it is in a hypercar – the Gemera – shows that Koenigsegg is pretty confident that it will provide the power it needs.Īs we mentioned in our previous article, each Quark delivers a peak power of 250 kW (335 hp). If you look at the Quark, you instantly notice that it is an axial-flux motor due to its shape. That’s why radial motors are more common in high-performance electric cars such as the Rimac C_Two and the Pininfarina Battista. The radial-flux motor has more power but less torque and the axial-flux unit works the other way around: it offers plenty of torque but with less power. This phenomenon is responsible for the few losses these highly efficient machines present. Furthermore, axial flux motors are generally more difficult to manufacture and present unique challenges in regards to the thermal design. Koenigsegg starts by reminding us that any topology suffers from magnetic flux leakage. ![]()
