From: Review of Design and Control Optimization of Axial Flux PMSM in Renewable-energy Applications
Structure | Advantages | Disadvantages | |
---|---|---|---|
SSSR | Simple structure, good heat dissipation | Large axial magnetic pull, low efficiency, Easy to damage | |
Torus | Torus-NS | Low torque ripple | High production cost |
Torus-S | Small iron loss | Large current ripple, difficult to control | |
AFIR | Small moment of inertia, High torque density | Large hysteresis loss, Large eddy current loss | |
Multi-disc | High output power, high power density | Large space occupancy |
