Question

What are the advantages and disadvantages of DC servo motors?

Answer 1

What are the advantages and disadvantages of DC servo motors, first of all, the advantages of DC servo motors:

1. The output power of DC servo motor is relatively high.

2. DC servo motor maintenance is relatively cheap.

3. DC servo motor has high motion efficiency.

4. The DC servo motor has strong overload capacity.

It has the advantages of high output power, vibration-free operation, high efficiency, high torque inertia ratio, less noise, good starting and speed regulation performance, and relatively cheap maintenance, but there are also certain disadvantages, such as DC power supply and complex structure.

Disadvantages of DC servo motors:

1. Special AC-to-DC power supply is required, and the power supply requirements are high

2. There is a brush structure inside, and there are problems such as noise, sparks, wear, and need to be cleaned

3. Short service life

Answer 2

DC servo motors are also becoming more and more common and have a wide range of uses. In fact, DC servo motors are DC motors that can be used to control. In general, DC servo motors are treated differently from DC motors. So what are its advantages that make so many merchants choose? And what are the disadvantages?

The advantages and disadvantages of DC servo motors are summarized as follows:

Merit:

DC servo motor these advantages and disadvantages which you do not know

1) Small size/light weight, and high efficiency;

2) Can work under low pressure, easy to make;

3) The use of high-function permanent magnet poles can reach rate/high power;

4) The system price of servo motor and servo drive is relatively cheap;

5) The rotational accuracy of the reaction and the positioning function and other basic functions are very high.

Shortcoming:

1) It is necessary to adjust the servo according to the demand of the load;

2) The powder that will show brush wear and cannot be used in a clean environment;

3) Brushes will be consumed and need maintenance;

Although the DC servo motor has the defects caused by the touch of brushes and commutators, the fundamental function can match the communication servo motor, and the usefulness is also close.

Moreover, the knowledge and manufacturing technology of DC servo motors and servo amplifiers have many things in common with AC servo motors, or choose DC servos or AC servos according to their own needs.
