You have a synchronous generator. The frequency is equal to the RPM divided by the number of pole pairs. That yields cycles per minute. Use a factor of 60 seconds/minute to get frequency in units of cycles per second, or Hz. Size of rotor does not appear in the equations. When you use RPM for the "speed of the rotor", size drops out.

Aaron says disagreement is acceptable but he objected to my persistence about proof of claim. So I'm not about to go there. But I remind you that all this mag neutralization, speed-up, cogging, etc is misdirection because it is unrelated to the issue.
