Contactless, high efficiency continuously variable transmission system with inherent overload protection

Advantages

• High efficiency
• Contactless, lubrication-free variable transmission
• Inherent overload, torque fuse capability
• Speed of prime mover matched with variable speed load

The high torque density low ratio magnetic gear concept has been extended by Magnomatics to create a variable ratio magnetic gear which can be used as an integral component in a continuously variable transmission (CVT) or Infinitely Variable Transmission (IVT). The magnetic CVT allows a variable speed drive to be connected to a fixed speed load, is highly efficient and compact, requires no cooling or lubrication and is suitable for applications as diverse as hybrid vehicles and wind turbines.
