Hello, I am doing the IPM_Motor_Flux_3D.pdf tutorial from Flux 2019.1, and when I reach page 12 of the "3D Overlay to create the geometry" (after I enter all the values to Create Non Meshed Coil and press OK) I got the following error message: Error message: Failed convert object : class cast error. Desktop updating step failed. I can not skip it because the winding parameters are very important to the study that I am doing. Hope you can help me with this. Thank you in advance Best regards.
Submitted by davewilson on Fri, 12/07/2012 - 01:58 Brushless Interior Permanent Magnet (IPM) Motors provide a high efficiency by using torque provided by the magnetic fields of a permanent magnet and the reluctance torque of the surrounding soft iron structure in which the magnets are embedded. The produces an interesting torque curve that combines the magnetic pole direction sensitive torque with the pole direction insensitive reluctance torque. This has the effect of skewing the peak torque curve based on phase current. The attached diagram below (you must be signed in to see and download it) shows the effects of varying the Iq phase current on the reactance/total torque ratio in a Prius IPM motor. We are currently using this diagram in our Texas Instruments Motor Control Seminar series. 04 Prius IPM Motor Current Ratio.zip
