Abstract
A magnetic clutch regulates rotational motion of a conveyor roller. A power transmission assembly with a transmission coil spaced from a receiving coil is energized to transfer energy from the transmission coil to the receiving coil. A clutch has a rotatably driven drive surface, and rotors magnetically coupled to stators. A shaft coaxially disposed along a longitudinal axis of the roller is coupled to rotors. The stators are coupled to the drive surface and are coupled to the receiving coil. The rotors become magnetically attracted to the stators to transfer rotational motion of the driving surface to the shaft and to a shell of the roller when energy is transferred to the stators in a first polarity direction.

A magnetic clutch assembly for use in regulating rotational motion of a conveyor roller in a conveyance system, said magnetic clutch assembly comprising:
- a power transmission assembly comprising a transmission coil spaced from a receiving coil, said transmission coil configured to be energized to wirelessly transfer energy to said receiving coil;
- and
- a clutch assembly comprising a drive surface configured to be rotatably driven, a first rotor configured to be magnetically coupled to a first stator, a second rotor configured to be magnetically coupled to a second stator, and a shaft coaxially disposed along a longitudinal axis of the conveyor roller and coupled to said first and second rotors, said first and second stators coupled to said drive surface and electrically coupled to said receiving coil;
- wherein said first and second rotors become magnetically attracted to respective said first and second stators via a magnetic attracting force to impart rotational motion of said driving surface to said shaft and to an outer roller shell of the conveyor roller when energy is transferred to said first and second stators in a first polarity direction.
A magnetic clutch assembly for use in regulating rotational motion of a conveyor roller in a conveyance system, said magnetic clutch assembly comprising:
