Motor design over the past century has been a thoroughly researched area; however, the
motor requirements for rotary blood pumps (RBPs) are typically unique in nature. As with
other applications, they are required not only to be highly efficient, reliable, and compact but
also to possess hemocompatibility characteristics, such as large clearances between the
rotor and stator and the use of noncontact bearing systems, to ensure long-term patient
support. An understanding of the interaction and production of electromagnetic forces inside …
