Working Principle of DC Servomotors
DC servomotors operate based on the principles of electromagnetism They consist of a stator and a rotor, with the stator being the stationary part that contains the field windings The rotor is the moving part that carries the armature windings and is connected to the load By passing a current through the field windings, a magnetic field is created that interacts with the magnetic field produced by the armature windings, generating torque that drives the motor.
The speed and position of the motor are controlled by varying the voltage applied to the armature windings This control is achieved using a feedback system that constantly monitors the motor’s position and adjusts the voltage to maintain the desired speed and position accurately.
