Next-Gen Axial Flux Motor / Generator

The Magnax Axial Flux Machine introduces a new generation of electric generators and motors helping innovators in wind turbines, electric machinery and heavy equipment to build lighter and more efficient products.

6 years of research and technology development on high-efficiency axial flux technology and 2 years of prototyping in collaboration with customers, resulted in a new technology for cleantech markets. 

Magnax Direct Drive Motors and Generators have an unparalleled power density resulting in much lower overall weight and size, while the efficiency is the highest in the market (96 to 98%).

Magnax Axial Flux Machines are the optimal solution for Direct Drive applications ranging from 100 kW to 20 MW.

Independent Bearing System

The large hollow shaft of the Magnax Machines provides ample space for the integration of a load bearing system.

This system is completely independent from the internal Magnax Machine bearing, so you can choose a load bearing system that perfectly fits your application. 

And due to the axial air gap, even small deflections of the bearing system do not affect the air gap.  

Of course, it is also possible to solely use the internal Magnax Machine bearing in cases where only torque loads are applied.

Direct Drive

Magnax Machines provide high torque at low speeds.

No gearbox is required, so no components are subject to wear and tear.

That’s a guarantee for reduced maintenance and downtime.
