Hi,<\/p>\n

<\/p>\n

I am trying to verify an induction motor’s magnetizing and leakage inductance parameters using Ansys Maxwell. The motor model that I’ve been working on has already been manufactured, which means I can perform experiments on it. I did a series of analyses using RMXprt, Maxwell 2D and 3D. Further, I performed no-load and locked-rotor tests on the machine to estimate the parameters.<\/p>\n

<\/p>\n

However, I noticed that there is a discrepancy between the inductance values of the motor for 2D-3D simulations and experimental results.<\/p>\n

<\/p>\n

Considering the results of locked-rotor test, I calculated the leakage inductance around 6-7 mH (which is actually reasonable).<\/p>\n

<\/p>\n

In Rmxprt, I obtained similar results (shown in the attachment).<\/p>\n

<\/p>\n

However as I obtained the inductance matrix in 2D and 3D, I recognized that the leakage inductance is calculated as 22 mH, which is too large. (also in the attachment. As $L_m$ can be found as $2 L_{ab}$ or $2 L_{ac}$, it can be found as 74 mH and $L_{ls}$ is computed as $L_a – L_m = 96-74 = 22 mH$.).<\/p>\n

<\/p>\n

How can I calculate the leakage inductance of an induction motor using Maxwell 2D?<\/p>\n

<\/p>\n

Thanks in advance.<\/p>\n
