Why Model Motor Faults with ANSYS Maxwell?3:53
In this lecture, we talk about why we simulating motor faults in ANSYS Maxwell You’ll learn how modeling faults such as demagnetization, winding short circuits, and eccentricity can help engineers anticipate performance degradation, analyze electromagnetic behavior, and diagnose issues early before costly failures occur in real machines.
Introduction to Different Faults in Electrical Motors17:28
I created this short podcast by combining information from different sources and reference documents to help students get a quick and clear overview of this topic. From the next video, we will start the step-by-step simulation process, but I still recommend listening to this file — it’s a new teaching method designed to deliver technical concepts in the form of a podcast for easier and faster learning.

General Simulation6:16
Simulate external supply faults for a PMSM in Ansys Maxwell using an external circuit. Configure three 120 V, 50 Hz sources with 0°, 120°, 240° phases and 3 ohm windings.
Results of Healthy machine11:16
One Phase Disconnected Fault8:31
Results of one phase open circuit6:01
Phase to Phase Short Circuit4:30
Model phase-to-phase short circuits in a pmsm using a subcircuit and a voltage-controlled switch with a pulse to time faults, export the netlist, and simulate a–b, b–c, and three-phase scenarios.
Results of phase to phase short circuit4:42
Imbalanced Input Voltage Sources1:31
Results of Unbalanced Voltage3:30
Plot flux lines to reveal the non-symmetrical stator field under unbalanced voltage, compare average torque and torque ripple, and assess phase C current and induced voltage to diagnose the fault.

Part 23:37
Part 12:41
Model magnetization fault in a surface-mounted PMSM with Maxwell, creating 2D/3D designs from an analytical model to compare healthy and demagnetization fault scenarios using torque, currents, and voltages.
Part 32:00
Result Comparison: Healthy, Partial, and Uniform Demagnetization in PMSM7:55
In this video, we compare the simulation results of a healthy motor with those affected by different demagnetization faults. You’ll see how partial and uniform demagnetization impact parameters like back EMF, torque, and flux distribution — helping you understand how each fault alters the motor’s electromagnetic performance and how such issues can be detected early through simulation.

Modeling Different kinds of Eccentricity in Ansys8:03
Results Analysis of Eccentricity Faults12:29
In this lecture, we compare the performance of a healthy induction motor with motors affected by static and dynamic eccentricity faults. Through simulation results, you’ll clearly see how each type of eccentricity influences the magnetic field, torque, and overall motor behavior. To better visualize these differences, an induction motor model is used, making the fault effects easy to understand and analyze through practical simulation results.

Requirements

Initial Simulation Skills using Ansys Maxwell (all needed materials are available in previous courses)

Description

Electrical machines rarely fail without warning—faults develop gradually and impact performance, reliability, and safety. In this course, you’ll learn how to model and analyze common motor faults using finite element method (FEM) simulation tools such as ANSYS Maxwell. Step by step, we will cover how to set up fault conditions, interpret results, and link simulations to real-world behavior. From the results and behavior of the machines, we can anticipate the failure in real machines before they stop working because of intensive fault or burnt wires.

You will see:

Demagnetization faults in the PM motors

Short-circuit faults (in-turn short circuit in windings and line-to-line)

Voltage unbalance and supply faults modeling

Rotor-related faults such as broken bars and eccentricity

Static, Dynamic, and Mixed Eccentricity fault modeling and the resutls

How these faults affect torque, losses, efficiency, and thermal behavior

By the end of this course, you will be able to create accurate simulation models of faulty motors with 3D and 2D model of FEA analysis in Ansys Maxwell, compare them with healthy operation, and gain valuable insights for condition monitoring, diagnostics, and fault-tolerant design.

More faults will be added to this course gradually by your suggestions in the reviews! so feel free to write your needed simulation there
