Abstract
A magnet rotor assembly is provided with a nonmagnetic ring, which can be made of an elastomeric material, which has at least one locating protrusion extending radially outward from a first surface of the ring. It also comprises at least one locking protrusion extending radially outward from the second surface of the ring. A plurality of permanent magnets are embedded within the nonmagnetic ring and spaced circumferentially around the nonmagnetic ring. The ring is shaped to be received within a rotatable component of an internal combustion engine, such as a flywheel, which has an internal cylindrical surface. The locking protrusions of the ring are shaped to elastically deflect in a radially inward direction in response to contact between the locking protrusions and the internal cylindrical surface of the rotatable component when the nonmagnetic ring is forced axially into the rotatable component. The locking protrusions then elastically rebound in a radially outward direction to move into a groove which is formed in the internal cylindrical surface only after the locating protrusions move axially into notches formed in the rotatable component.
