• A necessary evil: the air gap in rotating machines
  Efficient operation of electromagnetic devices requires that the magnetic circuit contain materials (such as iron) offering low resistance to the passage of magnetic flux; that minimizes the amount of electrical energy needed to create the magnetic field. However, gaps in the magnetic circuit are normally unavoidable: they contain air. Because that offers high resistance to magnetic flux, such gaps require undesirable increases in magnetizing current and the associated electrical loss. People concerned with machine alignment and bearing application and wear, and anyone who wants to know how rotating machines work, will appreciate this informative article. (Read an online summary.)
