Abstract :Permanent magnet synchronous generators with interior rotor insert ignore into journalissuearticles values(IR-PMSGs); have been widely preferred in micro wind turbines insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(NdFeB); permanent magnets insert ignore into journalissuearticles values(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.
