Abstract
In some examples, an electromagnetic clutch assembly. The assembly includes a pair of clutch plates including a first clutch plate configured to rotate around a rotational axis; and a second clutch plate configured to rotate around the rotational axis. The assembly further includes an electromagnetic coil circumferentially surrounding the air gap, wherein the electromagnetic coil is configured to generate a magnetic flux passing through the first clutch plate and the second clutch plate, wherein the pair of clutch plates define an air gap between the first clutch plate and the second clutch plate in the absence of the magnetic flux, and wherein the magnetic flux is configured to cause at least one of the first clutch plate or the second clutch plate to move to close the air gap.
