Abstract

A novel Integrated Motor Propulsor (IMP) is designed and analyzed in this paper. This IMP uses permanent magnet motor as its propelling machine , employs Halbach array on its rotor, and has a thinner rotor and bigger airgap. As owning complex structure and complicated working condition, IMP itself involves in the cross of multyple physics, and traditional analysis method can not meet with the needs in the design and calculation of this device. In this paper, A field-circuit-motion coupled time-stepping finite element analysis (FEA) model is presented to analyze the field-circuit coupled model of this device, cosidering influence from external circuit (for example, inverters). Multi-field coupling method is used and electromagnetism-thermal coupled model is established and direct coupling method is given to calculate electromagnetism-thermal coupling problem, considering interactions between two fields. At the end of this paper, according to the comparison between experiment and calculation results, effectiveness of the method presented above is verifid. DOI: http://dx.doi.org/10.11591/telkomnika.v10i7.1220
