The China 3v dc motor factory tells you DC servo motor classification:
According to the motor inertia size can be divided into:
1, small inertia DC motor-printed circuit board automatic drilling machine
2, the medium inertia DC motor(wide speed DC motor)-CNC machine tool feed system
3, large inertia DC motor-CNC machine tool spindle motor
4, special form of low inertia DC motor
Basic characteristics:
1, mechanical characteristics When the input armature voltage Ua remains unchanged, the speed N of the motor changes with the change of electromagnetic torque M, which is called the mechanical characteristics of the DC motor.
2, adjust the characteristics of the DC motor at a certain electromagnetic torque M(or load torque) under the steady state speed N with the change of the armature control voltage Ua, known as the DC motor adjustment characteristics.
3, dynamic characteristics from the original stable state to the new stable state, there is a transition process, which is the DC motor dynamic characteristics.
Common Uses:
1, the various types of digital control system in the actuator drive.
2, the need to accurately control the constant speed or the need to accurately control the speed of the dynamic driving curve.
