The brushed DC servo motor is a type of electric motor that is commonly used in applications requiring precise control of speed and position It is known for its simplicity, reliability, and affordability, which make it a popular choice in various industries such as robotics, automation, and manufacturing.
Operating Principle of Brushed DC Servo Motor
The brushed DC servo motor operates on the principle of electromagnetism It consists of a rotor, which is the rotating part of the motor, and a stator, which is the stationary part of the motor The rotor is connected to the output shaft of the motor and is equipped with a set of coils or windings The stator, on the other hand, contains a set of permanent magnets or electromagnets.
When an electric current is passed through the windings of the rotor, it generates a magnetic field This magnetic field interacts with the magnetic field of the stator, causing the rotor to rotate By varying the strength and direction of the current in the windings, the speed and position of the rotor can be controlled with precision.
