WebThe two internal fans or extended bars draw in ambient air from each end of the motor. This air cools the coil ends of the stator winding. On vented rotors the rotor bars act like fans and draw ambient air into the motor and through the a xial and radial vents in the rotor. This air is then blown through radial vents in the stator. WebDifferent Rotor Bars. There are various rotor slot shapes available and these depend upon the starting and rated load specifications, voltage/frequency (V/f) supply operation and the torque range. The rotor slot shape can be semi-closed, rectangular deep bar, rounded trapezoidal slots with rectangular teeth or completely closed rotor slots.
