This can be generalised as RPM = 120 x f / poles. Therefore # of poles = 120 x f / RPM. Since induction motors slip the full-load RPM will be somewhat less than the calculated speed. WebHigh resolution (12kcpm Fmax w/ 1600 lines is usually sufficient). There are also certain terms and frequencies which must be defined: FLine = 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. stardew valley ginger island fish
