Abstract
A motor winding includes a wire defining a rectangular cross-section and wound in a continuous direction about a coil axis to form a continuous coil including: a first coil segment spiraling in a first plane, defining a first external terminal, and defining a first interior end inset from the first external terminal and arranged on a first side of a coil axis; a second coil segment spiraling in a second plane parallel and offset from the first plane, defining a second exterior terminal parallel to the first external terminal, and defining a second interior end inset from the second exterior coil end and arranged on a second side of the coil axis opposite the first interior end; and a junction extending between the first plane and the second plane to couple the first interior end of the first coil segment to the second interior end of the second coil segment.
