ABSTRACT:
A magnetic coupling having two opposed annular arrays of angularly spaced permanent magnets magnetized to create magnetic north poles and magnetic south poles alternately spaced about each array. The north-pole and south-pole magnets of each array are tapered in cross-section from their surfaces at the gap to an annular surface of the array spaced from the gap, and permanent magnet spacer magnets completely fill in the space between the north-pole and south-pole magnets from the annular surface of the array at the gap to the spaced annular surface with the spacer magnets being magnetized generally transversely to the direction of magnetization of the adjacent north-pole, south-pole magnets so that the magnetic field created by the permanent magnets extends across the gap and annularly through each array to cause one of the arrays to rotate in synchronism with the other array.
