A860-2050-T321 FANUC pulse encoder
The working principle of DC servo motor is basically the same as that of ordinary DC motor. Electromagnetic torque is generated by the action of armature flow and air gap flux to make the servo motor rotate. Armature control is usually used to change the speed by changing the voltage while keeping the excitation voltage constant. The lower the voltage, the lower the rotational speed. When the voltage is zero, stop rotating. Because when the voltage is zero, the current is zero, so the motor does not produce electromagnetic torque, nor does it spin.

Dc servo motor is widely used in numerical control system, but DC servo motor also has some disadvantages: its brush and commutator are easy to wear; Limit of maximum speed of motor and application environment; The structure is complex, the manufacture is difficult and the cost is high.
