Magnetic gear reducers can advantageously replace conventional gear reducers to ensure speed and torque multiplication by using magnetic attraction instead of physical contact between moving parts. To date, complex assemblies, high weight and low torque have slowed the diffusion of this magnetic technology.
However, magnetic gears eliminate the need for lubrication and therefore minimize maintenance costs. No lubrication also means that mechanisms can operate at extreme temperatures (currently tested from -200˚C to 350˚C).
These advantages are particularly attractive for applications with high maintenance costs or for those working in extreme environments such as satellites and other aerospace devices.
Along with usage and corrosion, wear is one of the three main factors limiting the life and performance of mechanical components and technical systems. With magnetic reducers, the absence of friction not only eliminates wear of the system, it also has a direct impact on service life, which can be the key to maintaining mechanisms that cannot be easily replaced.
Material detached from the worn surface in conventional transmissions cannot be easily removed, which can be a significant cause of contamination. Contamination is a particularly serious problem for equipment that cannot be constantly maintained.
