Abstract:

© 2017, The editorial office of Transaction of China Electrotechnical Society. All right reserved. Amorphous alloys are considered as an appropriate core material for high-frequency motors because of their outstanding low power loss characteristics. When supplied by a PWM inverter, however, the harmonic losses of high-frequency motors will enormously increase. The key for designing and optimizing an amorphous alloy axial-flux permanent magnet motor is the fast and accurate calculation of harmonic losses during the original designing stage. In this paper, because of the large time consuming of three dimensional time step finite element analysis method, the present multilayer coupled model is further improved. An analytical method of air gap flux density is derived which can take high order carrier harmonics into account. The analytical methods of stator core losses and rotor eddy current losses are then deduced in consideration of the influence of eddy current reaction. The analytical calculation results of harmonic losses are compared with measured results and those obtained by the three dimensional FEA method. It is shown that the average calculation error of rotor losses is 9.69%, which means the improved analytical method features in high accuracy.
