Electric motors are the heartbeat of your operations—and when they fail, everything stops.
That’s why we created the IMS Maintenance & Reliability Guide:
a comprehensive, no-nonsense resource for plant teams, maintenance pros, and
reliability engineers who want to stay ahead of failures, not just react to them.

This guide walks you through everything you need to know to keep your
AC and DC motors running at peak performance. We cover:
 

• The most common causes of motor failure (spoiler: 52% are bearing-related)

• How to recognize early warning signs like vibration, overheating, or harmonic distortion

• Step-by-step inspection and testing procedures for both AC and DC motors—including visual checks, resistance testing, insulation tests, brush/commutator evaluations, and more

• Clear guidance on preventive maintenance schedules—what to inspect quarterly, when to perform vibration analysis or infrared scans, and how to prioritize based on criticality

• Real-world failure photos and diagnostic tips, so your team can recognize patterns and take action before small issues become big ones

• Wear pattern guides for bearings, brushes, and commutators with causes and solutions mapped out—great for training, troubleshooting, or post-failure analysis

This isn’t just a checklist—it’s a practical field reference, built from decades of hands-on motor repair experience. Whether you're troubleshooting a single motor or building a plant-wide reliability program, this guide will help you prevent failures, reduce downtime, and protect your bottom line.
