Abstract :The aim of this paper is to compare the performance evaluation in terms of the efficiency, cogging torque and manufacturing cost for a permanent magnet synchronous generator (PMSG) with interior rotor of N35 and N42 NdFeB permanent magnets (PMs) having same geometry separately used in a micro wind turbine (MWT). Firstly N35 type PMs have been used on an interior rotor, and then its performance has been measured and calculated by a MWT setup. After that, N42 type PMs have been used on other interior rotor. According to the obtained results, the PMSG with N42 type presented better efficiency than the PMSG with N35 type. But the PMSG with N42 type has induced a bit more cogging torque than the PMSG with N35 type. When comparing in terms of efficiency, a higher efficiency has been obtained by the PMSG with N42 type.
