FREQUENTLY ASKED QUESTIONS ABOUT AXIAL FLUX TECHNOLOGY
Below you can find the most common questions about our technology and products.
Traxial doesn’t sell directly to consumers. We supply our motors to OEMs and Tier 1 automotive companies.
Our focus is on ground e-mobility, but we can set up a custom non-recurring engineering trajectory for specific projects.
This is possible under NDA.
Please contact us to receive technical specifications.
Yes, our Traxial axial flux motors can also be used as a generator.
Yes, the form factor of our motor is ideal to connect multiple motors in parallel and as such, multiply the torque and power of the electric motor. However, this does require technical customization of our design. Please contact us to discuss this in more detail.
Our machines stay below 1200 Hz, which means that no exotic power electronics are required. Traxial machines are designed to work with off-the-shelf inverters. Our machines can be used in 4-quadrants operation by using the 4-quadrant inverter of your choice. The main requirement is that the inverter can handle permanent magnet motors.
No, but we’re open to collaborations with battery suppliers.
Yes, the electromagnetic principles of our axial flux machine are similar to radial flux machines meaning you can reach higher motor speeds by reducing the electromagnetic force.
We recommend 800V because it’s easier to reach higher power levels at high voltages. It also decreases the overall weight of your powertrain. However, we can adapt the motor to your voltage level by modifying the windings. Keep in mind that decreasing the voltage results in an increase in current, so the inverter must be capable of coping with these higher currents to maintain the same power level.
Yes, our machines are equipped with a PT1000 temperature sensor.
No, but Traxial motors can be combined or integrated with existing or new gearbox solutions on the market.
Yes, a reduction gearbox can be combined with Traxial machines. This results in a very compact solution.
The closed versions of the Traxial yokeless axial flux motors are IP67.
A rule of thumb is that torque increases by increasing the radius while the speed gradually decreases. The limit of your radius mainly depends on the strength of your materials. Please contact us for a specific inquiry.
Our motors are oil-cooled.
This varies from 5 to 30 seconds, depending on the starting conditions. The primary influence on the overloading time is the chosen cooling strategy. We can expect better overloading capacity from a liquid-cooled machine than when it is air-cooled. Peak torque (overloading torque) is approximately twice as high as the nominal (continuous) value at a given speed.
