	122 - Inductance Analysis of an IPM Motor -d/q-axis Inductance Obtained by Actual Measurement-	Module:DP	2011-02-28
	Evaluating the inductance along the d/q-axis is important to analyze the teeth of a rotor in an IPM motor. The d/q-axis inductance accounting for the current phase can be obtained using the PM motor inductance tool, but this inductance cannot be obtained from actual experimentation. However, the d/q axis inductance at the current phase 0 degrees which can be obtained from actual experimentation can be calculated by converting the inductance of one-phase of coil into three phases for each axis.This example presents the use of a magnetic field analysis to obtain the d/q-axis inductance by converting the inductance of the phase coils to three phases and two axes.

	101 - AL-Value Current Characteristic Analysis of a Choke Coil	Module:ST	2011-01-17
	The AL-value indicating the inductance for the number of turns of a coil is one of the vital parameters when designing a transformer or choke coil. Analyzing the current characteristics for the AL-value using a simulation is advantageous because the AL-value is often set by the design specifications and the AL-value varies with the input current. This example presents the use of a magnetic field analysis to obtain the AL-value current characteristics of a choke coil.
