摘要：The Permanent magnet synchronous motor
(PMSM) has been widely applied in a pulse width modulation
inverter-fed adjustable speed drive (ASD) system. However, the
radiated electromagnetic interference (EMI) from PMSM are
proved to be non-negligible by experiments in radiated emission
test. Since numerical methods in time domain have advantages
in calculation electromagnetic fields over those in frequency
domain. To this end the field-circuit coupled finite integral
method in time domain is highly suggested to evaluate the
radiated EMI from PMSM. In this paper, a simplified 3D EMI
model of PMSM is developed and the current of motor windings,
as the supply sources of radiated fields, are obtained by
measurement. Besides, the field-circuit coupled method is
employed to estimate the radiated EMI from PMSM. The
effectiveness of the developed methodology is verified by
implementation of experiments and simulation results show
acceptable agreement with the experimental results.
