Model elicitation of interior permanent magnet synchronous motor drive by sine source

This paper introduces a survey about model elicitation of interior permanent magnet synchronous motors (IPMSMs). In many cases, the magnetic flux of these motors contains significant higher harmonics due to their real design. From this reason, the classic model in d, q reference frame (Clark-Park transformation, space vectors) doesn´t describe exactly the motor behavior. For motor without damper winding, the model in a, b, c coordinates has been elected and determined. Elicitation was done by several measurements with 1-phase sinusoidal voltage source and scope. The measured and evaluated parameters, which are carried out on developed laboratory prototype of IPMSM by two proposed measure methods, have been shown and compared.
