Hi Steve,

You can try the ns = (120 x f) / P to calculate the synchronous speed in RPM.

The revolution per minute (RPM) denotes the phase difference.

You need to identify the number of poles (P) .

The formula above is simplified from

1 freq. = 60 cyc,
poles assumed by 2 = they are calculated in pairs

You can do the math.

or try to check the table I attached.

Hope it helps.

God Bless.

Best,
Neil
