Abstract: An electromagnetic machine includes a motor housing defining a cavity therein, and a stator disposed within the cavity. The stator has an external surface and a plurality of mounting ears each configured to receive a fastener and extending from the external surface towards the motor housing. The assembly includes a tunable insert ring disposed between the motor housing and the stator. The tunable insert ring and the stator define at least one cooling channel therebetween. The tunable insert ring encircles the external surface and includes a plurality of projections each extending towards and disposed in contact with the stator to thereby stiffen the electromagnetic machine and minimize vibration of the stator within the motor housing. A device including the electromagnetic machine is also described.
