General Closed-form Analytical Expressions of Air-gap Inductances for Surface- mounted Permanent Magnet and Induction Machines
نویسندگان
چکیده
General closed-form analytical expressions for airgap inductance of surface-mounted PM and induction machines are derived without the assumption of sinusoidally wound windings. The expressions are suitable for all singleor doublelayer, concentrated or distributed windings, and demonstrated to be identical with the winding function approach and share the same advantage that all the harmonics are inherently included. These expressions are straightforward analytical equations, which are easily used by machine designers.
