The general arrangement of a three phase waveform. Computer Numerical Control Machine (CNC) at Nickerson “NSF/ANSI 61.” NSF RSS. The Public Health and Safety Organization, n.d. Web. 07 June 2017. 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.

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. 380 Series Vertical Inline Pump with VFD Image Info Dimensions 255 × 255 Name SPLIT-CASE-copy-1.jpg Mime Type image/jpeg Type JPG Size 21.33 KB
