ABSTRACT:
The soft start of a permanent magnet coupler of the type in which magnetic flux from permanent magnets on a rotary magnet rotor bridges an air gap between the magnets and an electroconductive element on a rotary conductor rotor to magnetically couple said rotors together responsive to relative rotary motion between said rotors, is adjusted by changing the amount of flux which bridges the air gap. This is accomplished by attracting some of the flux to magnetic material selectively positioned on said magnet rotor adjacent one or more of said magnets.
