In the servo system, the speed of the motor and the working state should be changed according to the command signal, so the DC motor used in the servo system is called a mass servo motor. According to the role and characteristics of servo in the system, the system puts forward the following requirements for its performance: 1. The corresponding frequency as high as possible also reduces the moment of inertia of the rotor as much as possible, and increases the rotational distance-moment inertia ratio. 2. Good smoothness. 3. The speed regulation range is as wide as possible 4. The hardness of mechanical characteristics △T/△n is as large as possible 5. The contact spark between the commutator and the brush is as small as possible to reduce servo noise 6. Strong overload capacity.
