Zusammenfassung:Modification of the induction motor into a permanent magnet synchronous generator is to put a permanent magnet on the squirrel cages stator to generate the magnetic pole as a replacement for the electromagnet pole produced at a separately excitation of the conventional synchronous generator called the Permanent Magnet Synchronous Generator (PMSG). The purpose of this research is to design PMSG by modification of induction motors into permanent magnet synchronous generator with 24 slots 16 pole by using radial flux and utilizing stator. This research is a software-based FEM (Finite Element Method) for design and the magnetic Material used for permanent magnet synchronous generators is Neodymium Iron Boron (NdFeB). The PMSG on this design obtains the back EMF constant for its half-cycle of 4.902 rad/s and gets a voltage of 191.455 Vdc at 375 rpm speed and when given the loading of 100 Ω at 375 rpm speed produces a voltage of 176.73 Vdc, the current of 1.77 A and the output power is 313.24 Watt with efficiency reaching 85%. The PMSG modelling is done to have a specification of 24 slots 16 poles, changes the the characteristic Induction motor with synchrounous speed of 1500 rpm becomes as low as 375 rp. So This PMSG modification can be used as wind turbine or microhydro power palnt with low speed prime mover energy.
