Motor Noise and Vibration (NVH) – Integer-slot and Fractional-slot Harmonic Analysis I originally planned to continue to derive the order and frequency of electromagnetic force according to the classification of radial force. When analyzing the spatial order of the magnetomotive force generated by the stator armature winding, the performance of integer slots and fractional slots …

Demagnetization simulation method of IPM permanent magnet synchronous motor in ANSYS Maxwell R18.1 This case is about the demagnetization of the rotor magnets caused by excessive current. It is necessary to demonstrate the comparison of each opposite electromotive force of no-load operation analysis before increasing the current, and the comparison of each opposite electromotive force …

ANSOFT Modeling 1. Establish the motor model in ANSOFT software Step 1: Draw the motor model in ANSOFT Step 2: Select the “Export” item under the “Modeler” menu and the following window will appear. Select to save as a “step” format file. You can now exit the ANSOFT …
I did a Maxwell-simpler cosimulation of PMDC . It feels much more complicated than AC induction motor, mainly because neither MAXWELL nor SIMPLORER has a commutator module for PMDC, and all must be controlled by switches. For simplicity, the motor model uses the simplest three-slot motor, and the mesh is fully automatic.Finite element model and …
