    I quote the following from the lesson on synchronous motors:

    "The three phases of stator excitation add vectorially to produce a single resultant magnetic field which rotates f/2n times per second, where f is the power line frequency, 50 or 60 Hz for industrial power line operated motors. The number of poles is n. For rotor speed in rpm, multiply by 60."

    Regarding the rotating magnetic field speed is the red lined text correct?? I think it should be 2f/n, same synchronous speed?

    I agree.
