How many places must measurements be taken to check motor alignment?

To accurately assess motor alignment, it's essential to measure at multiple points to ensure that the motor shaft and the driven equipment shaft are properly aligned. Taking measurements at four distinct places provides a comprehensive analysis of the alignment situation. This method allows for capturing variations in alignment at different angles and positions around the shafts, which is critical for identifying misalignment issues that might not be apparent with fewer measurement points.

By measuring at four locations, operators can determine both vertical and horizontal alignment deviations and make necessary adjustments. This thorough approach helps prevent excessive wear on mechanical components, reduces the risk of premature failure, and ensures optimal performance of the machinery being aligned. Taking fewer measurements might lead to an incomplete understanding of the alignment, potentially resulting in operational problems down the line.
