This thesis examines the design and development of axial-flux permanent motor AFPM for the optimal performance. Two four-pole AFPM designs with same stator design, radial size and excitation is constructed and tested with different rotor geometries having distinction of induction rings and enclosing magnet within the rings. The two designs type-1 and type-2 are analyzed with and without magnets as synchronous and induction motors for comparative study. Both the designs are analyzed with rotor having separate ring and cage ring induction structure enclosing magnets. The starting of axial flux permanent magnet motors is based on induction principle like that of squirrel cage motor. The transient analysis includes the comparison using speed, torque, harmonics in current during startup. The designs are also tested and compared under no load and different load conditions. Steady state analysis includes comparative analysis of Input and Output power, losses and efficiency. Magnetic analysis is also performed for comparison which covers flux densities distribution in geometry and airgap of synchronous motor design types. The analysis and results could be used for further development in design of axial-flux motors.
