Magnax is proud to announce its participation in the EU-funded HARMONY project—an ambitious effort to strengthen Europe’s independence in the supply of Rare-Earth Permanent Magnets. As Traxial (Magnax's e-mobility subsidiary, we are leading the technical development efforts for this project,…
Achieving maximum power density in electric motors requires careful consideration of topology and design choices. We’ll be exploring the five design decisions we've made in our design of the next generation electric motors to achieve massive gains in power density.…
The dominant trend within the automotive industry for battery electric vehicle (BEV) traction electric motors is the use of permanent magnet synchronous machines (PMSM), and within that category, the internal permanent magnet (IPM) radial flux (RF) machine seems to be…
At Traxial, we've put our yokeless axial flux motor head-to-head with the latest Tier1 radial flux motor. The results? Our innovation leads the way in power, efficiency, and sustainability. The Numbers Don't Lie Our comparative analysis reveals impressive material reductions across…
The following article was originally published by Emobility Engineering magazine, published April 11, 2024 Read the original article Touted as the future of EV propulsion, axial flux motors are more compact, lighter and offer higher power and torque densities than…
As the electric vehicle growth continues unabated, the rising fuel prices due to supply chain disruptions and political tensions will continue to incentivize consumers to consider more fuel-efficient battery electric vehicles (BEV’s) and hybrid electric vehicles (HEV’s) further accelerating their…
The unique selling proposition of yokeless axial flux machines over their state-of-the-art radial flux cousins are: Up to 3x the torque density Up to 2x power density Typically 1/3 of the axial length Around 45% lower CO2 footprint 1. AXIAL…
The following blog post is the third in a 4-part series based on a paper presented at the 2023 CTI Symposium in Berlin by Traxial founder Peter Leijnen. See Part 1, Part 2. and Part 4 1. THERMAL CHALLENGES Thermal…
As explained in Part 1: Axial Flux versus Radial Flux, the flux path of yokeless axial flux machines is a lot shorter compared to a radial flux machine. In the latter machines, the flux must “take a bend” in both…
Machines with a yokeless axial flux and radial flux permanent magnet have a lot in common. In fact, from an electromagnetic perspective, they are almost identical. Both work on the same electromagnetic principles, and both have copper windings, iron cores,…
The history of electric car technology started over 200 years ago but it’s only since the renewed interest in the last decade that we’ve witnessed several technological pushes. For powertrain electrification, manufacturers are looking into the potential of system integration…
In the first phase of vehicle electrification, the focus was on acceleration and speed. Nowadays, the design parameters go beyond performance and touch on requirements that should not only improve efficiency but also the driving quality and safety. For these…
Future car sales have already been limited to emissions-free all-electric models by 2035 and we’re now also seeing several countries laying the first foundations toward zero-emission road mobility targets for commercial vehicles. That’s no surprise if you investigate the share…
The first automobiles were introduced more than a century ago. Over the years, and like any other business, car manufacturers have had to adapt to market changes to retain their competitive edge. One of these challenging market changes was the…
Compared to traditional radial flux electric motors used in the majority of automotive applications, axial flux machines, especially “single stator – double rotor” topologies, are more effective in an electromagnetic sense. This blog post explains why. Creating magnetic fields to…
Anti-EV provocateurs often refer to the total carbon footprint, where an electric car is only as green as the source of electricity the consumer uses to charge it, and where the environmental cost of lithium-ion batteries needs to be taken…
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. From an electromagnetic perspective, as already known for a long time…
If you’re familiar with electric motors, you’ve probably noticed that not all axial flux motors are the same. Traxial opted for a single-stator double-rotor (SSDR) configuration, while other axial flux motor developers use a double-stator single-rotor (DSSR) disc-type structure. Maybe you’ve…
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,…
