Patented Technology


There are no mechanical moving parts to seal the vane against stator housing in a Magnevane motor, drastically improving life of motor, and removing the high risk mechanical failure which can result in sparking.
Patented tangentical positioned magnets in the vanes and the improved conical core magnets create a stronger seal against the stator housing, ensuring strong and reliable start up torque from very first turn.
Neodymium magnets lose less than 1% of their strength over 10 years. Super magnets, as they are called, strengthen (and improve the seal) above and below ambient temperature increasing performance of motors even further.
The Magnevane output curve remains constant throughout the life of the vane due to the consistent and long life of Neodymium magnets, while competitors’ performance falls significantly with each mm of vane wear.
Magnevane has developed the first motor that can accommodate for self lubricating stators implemented in our standard, ATEX and food grade motors. With special composite vane material we can deliver complete non lubricated motors and still achieve full performance and power longevity curves.


Magnevane developed a rotor for pneumatic motors that is disruptive and distinct from the market paradigm to date, using the patented concept with magnets in the rotor core. Concretely, a cylindrical rotor body was designed with a set of longitudinal vanes, where each vane was partially inserted into a slot. During the operation of the rotor, the vanes are pushed against the rotor body by the forces of the axial arrangement of the magnets with opposite polarity. The axial arrangement of the magnets can undergo changes and present a variable number of magnets, according to the intended application, but always with the same gains in terms of air consumption and power due to the practically perfect sealing.
In this sense, the rotor achieves significant improvements in energy efficiency and substantial power increase, compared to the applicable state of the art, characterized by less efficient and limited solutions, for example in terms of materials and components used (eg , springs), geometry and volume of the compression chamber.
This patent and the underlying technology represents the Magnevane technological core in terms of disrupting the state of the art. However, in order to introduce significant improvements, ensure transversal application and, subsequently, launch new products, new R&D cycles of complementary and disruptive technologies were developed


Magnevane R&D developed special pneumatic motors’ vanes in order to further increase sealing and performance. In this context, a more efficient vertical sliding vane has been developed that repels the rotor, significantly improving its energy efficiency. Due to the innovative characteristics of the new technology, known as the repulsion of tangential vanes, there was a need to make adaptations to the rotor that would make it possible to integrate these vanes.


Magnevane identified another component with the potential to significantly improve the performance and energy efficiency of pneumatic motors. A new concept of end caps with a Y shaped groove facilitates the mechanical process of sliding the vanes inside the rotor, especially in situations of reduced pressure levels, significantly improving the sealing effect on the stator. This improvement resulted, once again, in superior performance and performance and was also registered as a patent.


Specially developed for small motors where the magnets impose minimum limits on the stator sealing, this innovative U shape end cap concept with an air passage system in the rotor through holes, provides practically perfect sealing of the rotor and an increase in energy efficiency compared to other types of available rotors. This technical-scientific progress achieved is also registered as a patent.
