Abstract
A segmented stator for an electric motor comprises: a plurality of tooth segments arranged in a circular configuration, the tooth segments having body portions and front surfaces extending inward from the body portions; and wire wound on the body portions. A distance between adjacently positioned front surfaces of the tooth segments is less than a width of the wire. The wire wound on the body portions substantially fills space between adjacently positioned tooth segments.
