The speed of the rotating magnetic field 2πf1 ωsyn = P/2 60f1 nsyn = P/2 (rad/s) (rev/min) or where f1 is the frequency of the stator current, and P the number of poles. 2. The rotor speed of an induction machine is generally different from the speed of the rotating magnetic field. The percentage difference of speed, known as slip, is defined as s= ωsyn-ωm nsyn-n = n ωsyn syn where ωm and n are the speed of the rotor in rad/s and rev/min, respectively. 3. The induced emf in one phase of the stator winding is E1 = 4.44f1N1kw1Φm and...
