National Pump Vertical Turbine Pumps, API 610 Vertical Lathe Figure 1. The general arrangement of a three phase waveform. Figure 2. A simple sine wave with a period of 360° and an amplitude of 1. 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. Model 411 Horizontal Split Case Utah Lake Cascade Pump Custom shapes cut from raw materials. Figure 3. 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.
