This is my first post, so I'll give a bit of an intro. I am an marine engineering cadet at mass maritime academy in my junior yet. I took physics II last semester and this semester I am taking electrical machines.
In class today we were talking about how fast motors can rotate and came up with this equation:
Ns = 120f/p Ns being the speed of the motor, f being the frequency and p being the number of poles.
with this equation using 60hz and a 2 pole motor it says that a motor will only rotate at 3600 rpm's.
I know this isn't true because wood working routers rotate well over 15,000 rpm.
I asked my Proff how this worked and was told to try and find an answer for next class.
I haven't been able to find anything searching google about it. Does anybody know how this works?
Thanks Cooper
