/www.thestudentsurvey.com/ The number of poles and the frequency of the applied voltage determine the synchronous speed of rotation in the motor's stator. Motors are commonly configured to have 2, 4, 6 or 8 poles. The synchronous speed, a term given to the speed at which the field produced by primary currents will rotate, is determined by the following expression: Synchronous speed of rotation = (120 x supply frequency)/Number of poles on the stator. In our case, a 3-phase, 20-pole induction motor is connected to a 600 V, 60 Hz source. a. What is the motor's synchronous speed? b. If the voltage is reduced to 300 V, will the synchronous speed change?
