The paper presents a single phase, slotless axial flux permanent magnet synchronous machine for induction heating gen sets. A full scale prototype of the machine (110 kVA, 400 Hz, 690 A) has been designed and subsequently analyzed through FEM analysis (FEA). Induced current distributions in the permanent magnets (PMs) and in the rotors are also calculated through FEA and it is seen that the resulting losses are kept at bay due to the large air gap. This key feature allows the machine to achieve a high rated efficiency (94%). The prototype has also been built and experimental tests confirm the results obtained by FEA.

Abstract
The paper presents a single phase, slotless axial flux permanent magnet synchronous machine for induction heating gen sets. A full scale prototype of the machine (110 kVA, 400 Hz, 690 A) has been designed and subsequently analyzed through FEM analysis (FEA). Induced current distributions in the permanent magnets (PMs) and in the rotors are also calculated through FEA and it is seen that the resulting losses are kept at bay due to the large air gap. This key feature allows the machine to achieve a high rated efficiency (94%). The prototype has also been built and experimental tests confirm the results obtained by FEA.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
