Abstract :In this study, radial brushless motors with internal permanent magnet insert ignore into journalissuearticles values(IPM); is designed and modelled. These motor types can be fed by alternating current insert ignore into journalissuearticles values(AC); and direct current insert ignore into journalissuearticles values(DC); sources. It is called permanent magnet synchronous motor when it is fed with a AC voltage, and brushless direct current motors when it is fed it with a DC voltage. Later on, design parameters of an electric motor that produces a torque of approximately 35 Nm, powered by a 72 V DC source is determined. Then, mathematical modeling is implemented based on the determined design parameters of permanent magnet electric motors. IPM motor’s size, magnetic and thermal analyses are made by finite element analysis. Moreover, efficiency, torque and power of the designed IPM motor are calculated as the result of the analysis. Finally, it is revealed that the designed IPM motor has 24 slots and 8 poles which has an efficiency of 92 %.
