WebIn this animation, the rotating air-gap mmf (Tesla’s rotating magnetic field) in an elementary two-pole, two-phase, symmetrical stator is explained. First, we create the rotating air-gap mmf field by applying balanced two-phase voltages to balanced stator windings, which causes symmetrical two-phase currents to flow. WebThe mechanical speed of rotation of a magnetic field due to the fundamental electrical current, fe is very important and is given a distinct name, synchronous speed, ωs . Synchronous speed in radians per second is defined as: ωs = 4πfe p. It is common to use units of revolutions per minute, (rpm) to describe rotational speed.
