Permanent
magnet synchronous generators with interior rotor (IR-PMSGs) have been widely
preferred in micro wind turbines (MWTs). Customers demand high output power of
the MWTs. Therefore, in this study, performance analyses and optimizations of
two IR-PMSG rotors were practically carried out to increase the output power of
the MWTs by employing N35 and N42 Neodymium-Iron-Boron (NdFeB) permanent
magnets (PMs) with same geometry used on IR-PMSG rotor surfaces. For this
purpose, two IR-PMSG rotors were designed with same geometry and applied to a
pole shifting reduction technique to decrease their cogging torque on the
IR-PMSGs as well. According to the obtained results, comparing the performances
of the IR-PMSGs with both N35 and N42 NdFeB PMs on a MWT with regards to their
power coefficients, an increase of 18.6% in power coefficient of the IR-PMSG
with N42 NdFeB PMs was calculated.
