ABSTRACT:
A torque limiting clutch having two or more cylindrical magnetic rings with coplanar edges abutted to a flat surface portion at one side of a magnetic driven member which may be a flat plate. The rings may be cylindrically round, or polygonal with flat sides. Between the rings are ring-like, cylindrical, arcuate, or flat permanent magnets conforming to the radial spacing of the rings and maintaining a magnetic circuit or circuits with the driven plate. A flat bar or other mechanical drive means engages the free other edges of the rings and is driven rotationally by a motor drive shaft or other driving means. The driven plate carries a driven shaft, or is adapted for engaging driven gear means or a driven pulley belt.
