Abstract
An electric machine includes a rotor, a first tooth portion, and a second tooth portion spaced apart from the first tooth portion and cooperating with the first tooth portion to at least partially define a rotor opening. At least a portion of the rotor is disposed within the rotor opening. A bridge has a first end connected to the first tooth portion and a second end connected to the second tooth portion such that the bridge defines a portion of the rotor opening. An aperture is defined by the bridge and is disposed between the first end and the second end.
