A magnetic toroid and a magnetically drive rotary coupling device comprising it

Abstract

The present invention relates to a magnetic toroid (100) characterized by a Mobius-like toroid twisted to one degree, wherein the cross-section of the Mobius-like toroid has a closed shape with at least four straight sides, wherein each side of the Mobius-like toroid is orthogonally magnetized to form the magnetic toroid (100), thus creating a magnetic field that has rotating polarity around the magnetic toroid (100) when the magnetic toroid (100) is rotating about its centerline. The present invention also relates to a magnetically driven rotary coupling device (200) comprising a first magnetic toroid (101) and a second magnetic toroid (102) arranged adjacent to the first magnetic toroid (101), wherein the first magnetic toroid (101) can rotate about its own axis with respect to the movement of the second magnetic toroid (102) when portions of their respective magnetic fields interact with each other.
