Step 5: Enter Motor Data
Enter Motor Poles
If the number of motor poles is not on the motor nameplate, contact the motor manufacturer and confirm the number of
motor poles. The number of motor poles is ALWAYS an even integer multiple of 2.
Use this table to help determine the number of poles. The motor NP RPM is always less than the Sync RPM by the
amount of motor slip RPM. If the motor NP Hertz is not 50 Hz or 60 Hz, or if the motor has a low NP RPM, contact
the motor manufacturer and confirm the number of poles.
