Working Principle of Brushed DC Servo Motors
Brushed DC servo motors operate on the principle of electromagnetism, where electrical energy is converted into mechanical energy These motors consist of two main components: a stator and a rotor The stator is the stationary part of the motor that houses the magnetic coils, while the rotor is the rotating part that carries the permanent magnets.
When an electrical current is applied to the stator coils, it creates a magnetic field that interacts with the permanent magnets on the rotor This interaction causes the rotor to rotate, producing mechanical motion By controlling the magnitude and direction of the current applied to the stator coils, the speed and position of the rotor can be accurately controlled, making brushed DC servo motors ideal for applications requiring precise motion control.
