Checking rotor runout is a crucial step in ensuring the proper functioning and longevity of rotating machinery, such as electric motors, generators, and turbines. It involves measuring the deviation of the rotor’s surface from a true circle, which can occur due to manufacturing imperfections, wear, or damage.
Accurate rotor runout measurements are essential for maintaining optimal performance, preventing premature bearing failure, reducing vibration, and ensuring efficient operation. Historically, rotor runout was checked using mechanical dial indicators, which required skilled technicians and could be time-consuming. However, advancements in technology have introduced laser-based measurement systems that provide highly precise and automated measurements.
