Groove depth determination based on extended leakage factor in a 12-slot 10-pole machine
Presence of subharmonic components is a common feature of fractional slot machines, and the subharmonic is a main cause of rotor PM eddy current losses. As an effort to reduce the fundamental component of a 12-slot 10-pole motor, flux barriers are provided by making grooves on the back iron. The optimal groove depth ratio is found based on a extended (weighted) leakage factor by harmonic distance from the working harmonic number. The extended leakage factor reflects the PM loss by each harmonic component. The result is verified via finite element analysis (FEA).
