A Review of Techniques Used for Induction Machine Fault Modelling

Area of Science:

• Electrical Engineering
• Mechanical Engineering
• Industrial Automation

Background:

• Induction machines (IMs) are vital industrial components, acting as both motors and generators.
• Unexpected IM breakdowns cause significant economic losses due to unscheduled downtime.
• Economically unfeasible to study IM failures through destructive testing.

Purpose of the Study:

• To review and categorize existing computer modeling techniques for faulty induction machines.
• To provide insights into the benefits and drawbacks of different modeling approaches.

Main Methods:

• Review of literature on faulty IM modeling techniques.
• Categorization of models into electrical circuit-based, magnetic circuit-based, numerical method-based, and hybrid/FEM-based approaches.

Main Results:

• Identified four main categories of faulty IM models.
• Discussed the advantages and disadvantages of each model type concerning accuracy, computational time, and fault replication.

Conclusions:

• Faulty IM models are essential for understanding machine behavior and preventing failures.
• The choice of model depends on specific requirements for accuracy, speed, and fault simulation capabilities.
