An electromagnetic machine has a rotor and a stator core. The stator core has a plurality of radially-extending teeth and a plurality of bridges having opposite ends secured to corresponding teeth. Stator windings are positioned at least partially in slots between the teeth. Each of the bridges is in a compressed configuration and includes a midsection radially offset from the ends. In a method of making an electromagnetic machine, stator windings are wound around the teeth of the stator core while the stator core is in an expanded configuration in which each of the slots is relatively wider and the configuration of the stator core is changed after winding, for example by compressing or otherwise deforming the bridges, to a compressed configuration in which each of the slots is relatively narrower. The bridges hold the teeth in the expanded configuration facilitating high slot fill without using a segmented stator.
