How to Determine Speed for an Ac Induction Motor | 2000-09-30

Sep 30, 2000 · For a 50-Hz system, the formula would be: 50 x 60 x 2 = 6,000 no-load rpm ÷ number of poles. Using this formula, you can see that a four-pole motor operating on the bench under no-load conditions runs at 1,800 rpm (7,200 ÷ 4 poles). Note that when an ac motor is loaded, the spinning magnetic field in the stator does not change speed.
