Analytical calculation of slot leakage inductance in multiphase electrical machines

Opting for a multiphase electrical machine may provide, in several industrial cases, significant benefits in terms of performance, resilience and reliability. The interest in multiphase topologies is recently increasing due to the trend for more electric transportation and high power offshore wind turbines. In this paper, the classical analytical method for calculating the slot leakage inductance of three-phase electrical machines with double-layer windings are extended for other multiphase topologies.
