II. MOOEL OF INDU~TION MACHINES The dynamic model of a three-phase squirrel-cage Y-connected IM can be described in the stationary reference kame as shown in (1) as follows [ 11: The e!ectromagnetic torque equation can be expressed in term of stator current and rotor flux linkage
II. MOOEL VAN INDU ~ G masjiene Die dinamiese model van 'n drie-fase kourotor- Y verbind IM kan in die stilstaande beskryf word verwys Kame soos in (1) soos volg [11: ! Die e ectromagnetic wringkrag vergelyking kan word in uitgedruk termyn van statorstroom en rotor vloedkoppeling
