Construction of AC Servo Motor

 

  • As that of in the conventional motor. there is stator and rotor in the AC servo motor
  • The stator winding is wound for two winding, both windings are 90 degrees with each other. 
  • The constant AC supply is given to main winding or reference winding.
  •  The constant frequency variable voltage is given to the stator second winding or control winding. 
  • The variable voltage is controlled through electronic controller. 
  • The rotor of AC servo motor is designed for high resistance therefore the X / R ratio is very low. 
  • The torque speed characteristic of AC servo motor is linear due to low X / R ratio. 
  • The convention induction motor is applicable as servo motor but motor operation becomes unstable due to positive slop.

  •  The rotor of servo motor is either squirrel cage or drag cup type. 
  • The diameter of rotor is kept small in order to keep low inertia. 
  • The torque – speed characteristic of servo motor depends upon angle between two stator windings. 
  • The AC servo motor generally operates from 50 Hz to 400 Hz frequencies.
