Traxial Technology

Most of the electric vehicle motors on the market today are based on the radial flux topology, first conceptualized almost 200 years ago. In 1821, British scientist Michael Faraday created a machine based on a vertically suspended wire that moved in a circular orbit around a magnet; in 1834, the first-ever rotating electric motor that developed a significant mechanical output power was developed by Russian scientist Moritz Hermann Jacobi.

Today again, new electric motor developments are taking place, and the market is poised for disruption.

BREAKTHROUGH MOTOR INNOVATION SET TO REVOLUTIONIZE ELECTRIC MOBILITY

Introducing the next generation of electric motors, featuring new levels of power, efficiency, and manufacturability.
Based on axial flux technology, a concept first researched and patented by Nikola Tesla back in 1889, axial flux represents the future
of electromagnetic EV motors.

OUR TRAXIAL YOKELESS AXIAL FLUX MOTOR TECHNOLOGY OFFERS

LOWEST STATOR TEMPERATURE THANKS
TO DIRECT OIL COOLING

Our patented cooling system uses oil to cool the motor windings directly and uniformly.
This ensures a lower stator temperature compared to any other technology available, and eliminates hot spots.
This further increases the power densities that our Traxial motors can provide.

INTEGRATION INTO ELECTRIC
DRIVETRAINS AND E-AXLE MODULES

The advantages of axial flux technology, compared to conventional radial flux electric PM motors, are extensive: axial flux technology offers significantly increased power density, enabling longer range, lighter motor weight, and smaller motor size, opening up a host of new and more flexible options for powertrain design.

Our yokeless axial flux motor technology, incorporating years of research & development and in-depth collaboration with our customers and suppliers, features a pancake space-saving design topology that offers innovators in e-mobility the possibility to design and release more compact and efficient powertrain solutions. Thanks to the absence of the stator yoke, our yokeless axial flux topology provides a high power density combined with greater efficiency compared to other topologies.

DESIGNED FOR COST-EFFECTIVE MANUFACTURING PROCESSES

Our Traxial yokeless axial flux motor topology has been developed from the beginning with design-for-manufacturing in mind
minimizing manual labor, maximizing the use of automated production processes, focusing on cost effectiveness.

Each component can be manufactured using standard automated production processes, and can be
easily scaled for large series production and varying design parameters.

IMPACT OF OUR TECHNOLOGY

REDUCING RANGE ANXIETY WITH AXIAL FLUX

The Traxial yokeless axial flux topology offers a solution to one of the main concerns of electric vehicles: range anxiety. Copper and iron losses mainly determine the efficiency of an electric motor. We’ve developed solutions to reduce these losses significantly:

  • The absence of a stator yoke significantly lowers the iron mass and therefore the iron loss.
  • Concentrated windings with a very high copper fill factor result in optimal use of copper and as a result, low copper losses.

The Traxial AXF technology delivers the highest efficiency over a wide speed range, resulting in more vehicle range compared to traditional EV motors.

Additionally, our compact and lightweight design can easily be integrated into next-generation powertrain configurations, creating extra space for increased battery storage capacity.
