Three phase power has three identical sine waves overlapping at an offset of 2π/3 radians or 120°. When one phase reaches an x-intercept or node the next phase is only 30° and approximately 5.6 milliseconds from reaching its crest.

In single phase power the x-intercepts are 180° from each other. A full period is 360°. A single phase motor has a crest approximately every 16.5 milliseconds giving the motors a tendency to vibrate more, which may contribute to a shortened bearing life. 80 Series® Engine Driven Vertical Turbine Pumps, Deep Well Image Info Dimensions 650 × 650 Name Commercial-Pump.jpg Mime Type image/jpeg Type JPG Size 101.50 KB
