WebFLine = Electrical line frequency - normally 60 Hz (3600 cpm) or 50 Hz (3000 cpm). 2 x FLine = Torque Pulse Frequency. This is a common frequency found on a high resolution spectrum. P = # of poles on the motor. The number of poles is how the speed of the motor is controlled. The greater the number of poles, the slower the motor runs.
