MAG SOAR presents the new generation of magnetic gears in ESA

The technical director of MAG SOAR, Dr. Ignacio Valiente, presented Optimagdrive project final results in 2017 Mechanisms Final Presentation Days workshop. The project main objective was to demonstrate the potential capacity of magnetic gearboxes.

Magnetic gears have proven to be a better solution than conventional gears in applications where the extreme temperature or the maximum precision required implies serious problems for conventional mechanical gearing. For instance, robotics or space actuators.

The prototypes developed by MAG SOAR have been specially optimized for space requirements. Therefore, the minimum weight and the maximum reduction ratio have been considered the main priorities. Although the technology is recently making significant advances, up to now, the state of art still reflects some important limitations such as poor density torques and reduction ratios, magnetic contamination and overheating due to Foucault currents, undesired oscillations caused by high ripple torques… “We had the challenge of demonstrating a better performance in terms of torque with a very much higher reduction ratio”, explained Dr. Valiente.

As there were different points to validate, three different prototypes were developed in parallel to demonstrate some critical points in each one. The first and smallest one, with a diameter of 34mm, demonstrated a very high reduction ratio at one single stage with very low ripple torque. The second one fulfilled an optimal efficiency at high temperatures and significantly low magnetic pollution. Finally, the third prototype demonstrated a reduction ratio as high as 1:75.

In a nutshell, MAG SOAR has laid the foundations for a new coming generation of magnetic gears specially optimized for obtaining a maximum precision, efficiency and speed control at reduced weight. Dimensions, accuracy and torque parameters can be customized to meet different operational requirements.

Z-DAMPER nominated to the Clean Sky Best Project from Partners Award

CLEAN SKY is right now the largest European research H2020 funded program developing innovative, cutting-edge technology aimed at reducing C02, gas emission and noise level produced by aircraft.  This nomination confirms the big potential of Z-DAMPER for the control of vibrations at high temperatures and low frequencies.

Z-Damper is a magneto mechanism that matches mechanical impedances and provides a multiplier effect damping vibrations of both low and high frequency ranges more effectively.

Z-Damper optimum performance at extreme environments made this magneto-mechanism the perfect vibration killer to be used in one of Clean Sky major projects: the new counter-rotating open-rotor (CROR) developed by Airbus. CROR fuselage-mounted turbofans need a level of isolation of vibrations in a high-temperature environment that current damping technologies are not able to reach.

MAG SOAR SL, in cooperation with Universidad de Alcalá, developed and tested two prototypes following Airbus requirements. "Z-Damper has demonstrated a unique damping performance, even in extreme temperature environments. We have insight the birth of a new vibration isolation technology which applications are only starting to be foreseen", stated Dr. Valiente, technical director of MAG SOAR and scientific responsible of the project.

The northen lights are caused by the interaction between magnetic fields.

MAG SOAR BLOG TAKES OFF!

The magnetic energy´s faculties can be breathtaking. One of the most impressive proofs of this is the phenomenum know as the Northen Ligths, caused by the collision between the earth´s magnetic field and the solar wind. The acelerated electrons crushing against the atmosphere happen to offer us one of the most beautiful spectacles in the entire world.

The great potential of magnetic systems

MAG SOAR is well aware of the great potencial of magnetic force and that´s the reason why magnetism is used as main ingredient in the development of contactless mechanical systems which aplications range from aircraft mechanisms to space systems.

It all begun with the MAGDRIVE project, a magnetic gearbox optimized to work in cryogenic environments. The objective was to design, build and test a magnetic-superconductor non contact drive able to function at extremely low temperatures.

The results were outstanding: MAGDRIVE didn´t only satisfactorily pass every test but it also exceeded the initial expectations. The drive superconducting magnetic bearings were proven capable of suppressing every contact between moving parts. The lack of friction almost eliminates the fatigue of the system, one of the primary causes of the reduction of life time in all kinds of mechanical devices. Furthemore, it realeases the machinery from the constant need of lubrication and improves its efficiency.

The consequences and applications of this innovative system are countless. That is the reason which encouraged the team behind MAGDRIVE to create the spin-off company MAG SOAR.These are some of the products developed by MAG SOAR engineers:

To sum up, MAG SOAR´s objective is to take advantage of electromagnetic properties in order to unravel complex industry problems that traditional technologies have been unable to solve such as the high costs of maintenance and lubrication, mechanic limitations on extreme temperatures, problems caused by wear or fatigue…  In essence, MAG SOAR aim is to prove that magnetic systems can be the perfect choice to build and improve the present´s technology. Follow us and don´t miss a step of this thrilling adventure.
