Abstract :
The authors present an experimental approach to the modeling of the dynamic behavior of synchronous PM (permanent magnet) machines. They present a generalized model including an arbitrary number nd and nq of damper circuits, an experimental method based on standstill tests in the time domain, and a nonlinear method for identifying the equivalent circuit parameters. A procedure is also proposed for initializing the nonlinear method and determining the optimal equivalent circuits. The methods have been applied to experimental tests on a 10 kW 270 RPM PM synchronous machine and to a simulated experiment on the same machine, based on field calculations. The results clearly show a good representation of the dynamic behavior of the machine over an extended frequency range
