A double-rotor Traxial yokeless axial flux motor makes better use of the available space as it has a double air gap. On top of that, there is no space needed for a stator between the outer diameter of the machine and the outer diameter of the air-gap surface. In other words, the rotor spins alongside the stator, not within it. YASA&x27;s axial-flux design has efficiency at its core, offering efficiencies greater than 96 and an innovation roadmap to even greater efficiencies. quot;I was five weeks into my PhD at Oxford University, when I suddenly realised there was a much better way to build an electric machine called a torus axial-flux motor.
Low-speed efficiency and power density of the electric propulsion system can be further enhanced through use of Permanent Magnet (PM) motors, or more advanced radial-axial motor topologies 4, 6. Because axial-flux motors have a short axial length, . Here, too, the result is a power density that's twice as high as a conventional motor's, with higher efficiency to boot.
Compared to traditional radial flux electric motors, axial flux machines, especially single stator double rotor topologies, are more effective in an electromagnetic sense. This blog post explains why. Electrical Machines are designed to generate torque on a rotor shaft, thanks to magnetic forces created by magnetic fields.
TW Its important but as OEMs move to pure EVs, its efficiency thats becoming the most important characteristic, the figure that really drives the EVs range. And were pushing our YASA motors up to average efficiencies between 96 and 97 over standard WLTP drive cycles, whereas competitive products struggle to get much above 90. High- efficiency motors and sustainability. According to some studies, electric motors are responsible for about 45 of the total consumption of electric energy 1. If we focus the . Axial flux motors can also be highly efficient, with efficiencies typically over 96. Axial flux technology was already researched and patented by Nikola Tesla back in 1889, and the advantages of the technology compared to conventional radial flux PM motors are extensive.

Low-speed efficiency and power density of the electric propulsion system can be further enhanced through use of Permanent Magnet (PM) motors, or more advanced radial-axial motor topologies 4, 6. To improve electromagnetic performance, an axial-flux permanent magnet brushless DC motor (AFPMBLDCM) with unequal-thickness arc permanent magnets is proposed in this paper. Firstly, the structure and magnetic circuit of the AFPMBLDCM with unequal-thickness arc permanent magnets were designed. Then, the mathematical models and design method of the main parameters were derived. According to the. And we&x27;re pushing our YASA motors up to average efficiencies between 96 and 97 over standard WLTP drive cycles, whereas competitive products struggle to get much above 90. And that has a direct impact on range some OEMs tell us we&x27;re giving them a 5-10 range advantage against their competitors.
There is a new company (Magnax) specialized in axial flux motors. This is also a brushless motor design and can also be build as a wheel hub motor. It is basically superb in all aspects and allows for higher efficiency and at the same time very thin small designs. So my question Is this type of motor allready used in some EUCs (IPS comes into.

Manufacturing processes, cars, trucks, motorcycles, and now airplanes are making the move to electrons that Edison predicted more than a century ago. And they are all doing so for much the same reasons quieter operation, reduced maintenance requirements, better performance and efficiency, and a more flexible use of energy sources. Abstract For electric car propulsion systems, the wheel motor is an application that requires electrical machine shape flexibility, compactness, robustness, high efficiency and high torque. The axial flux machine is an interesting solution, where the motor is directly coupled or inside the driven wheel. In this paper, axial flux induction and synchronous machines as wheel.
