This course is designed to provide participants with a detailed and up-to-date overview of AC Induction Motor Troubleshooting. It covers the basic principles of AC induction motors and the common problems that occur with AC induction motors; the troubleshooting techniques and overvoltage and undervoltage protection; the power supply issues, power quality issues, voltage drops and phase imbalances; the motor circuit issues, motor circuit faults, protection systems for motor circuits and motor starter failures; and the mechanical issues, bearing failures, shaft misalignment and excessive vibration.
During this course, participants will learn the rotor bar and end-ring failures, rotor eccentricity and broken rotor bars; the stator winding failures, insulation breakdown and core failures; the control system issues and faults in the motor control system; the control system troubleshooting techniques; the thermal issues covering overheating, insufficient cooling and thermal overload protection; the miscellaneous issues comprising of environmental factors, electrical noise and load-related issues; and the common AC induction motor problems and solutions.
