Mechanical Maintenance for Motor Drive Systems 349

Mechanical Maintenance for Motor Drive Systems provides an overview of the most common mechanical faults found in motor drive systems and describes typical inspection methods for mechanical maintenance. Vibration is a major issue that can have very damaging effects. Shaft misalignment, shaft imbalance, looseness, and bearing issues are the four most common causes of vibration. Vibration inspection helps identify and correct the causes of vibration. Thermal inspection, ultrasound analysis, and oil analysis are also used during mechanical maintenance. Motor drive systems are widely used to power industrial machinery. For these systems to operate safely and efficiently, their mechanical components must be in good working order. This class provides information that helps users understand major mechanical faults and how to identify and fix them. This information helps reduce unplanned downtime and expenses.
