While a line synchronous AC motor would turn at 1800 or 3600 rpm, depending on how it's wired, a typical induction motor turns at 1725 or 3450 rpm. The more you load an induction motor, the slower it turns and the more torque it exerts on that load. ... 1140. How does a fan motor work? — JM, Toronto, Ontario...
