The perspective on choosing a servo
As a modern time invention, servo motors are undergoing much praise and criticism. Servos have numerous applications across very different industries, so people have a lot to say about them. But is it true that the motor increased the capacity of manufactures and made not only the working process but the life itself easier than it was before?
Many people consider frameless servo motors the best option at hand. But is it the best choice for your project? To discover the best fit as with any other motor you could consider using there has to be a thorough research of the product! So, let us go through a number of advantages and disadvantages to see the benefits of servos more clearly!
Servos have countless advantages over other types of motors and here is why:
- Does your industry require precision? Servos are known for being exact in their positioning which is crucial for tons of machinery. The efficiency depends on it. Can u imagine a robot with sloppy movements? We can not have such a performance as it might (definitely) hurt somebody at a workplace.
- The absence of a commutator and brush system in brushless servos eliminates the need for periodic maintenance. So no additional fees!
- Time is valuable, especially when it comes to business. Thus, servo motors don’t require as much time to be installed and can be easily implemented into the machinery with no special help. They also allow for adaptation (which is not the case with others).
- The market is growing, meaning that there are more options and more competitors trying to prove that their product has the best quality and price. It is now easy to find servos in almost any country.
- Now, the performance of these motors are far superior to steppers or pneumatic actuators as they have a considerable number of drawbacks hence a slower speed to a lack of motion).
- In most of the cases, servo motors are proving to be the best fit and show far superior performance capabilities.
- It has no environmental constraints. Brushless servo can be used in almost any environment. For high-temperature operations, the usage of a resolver avoids any electronics buried in the motor.
Nothing is perfect, nor servos are without a fault. A number of small disadvantages are connected with the use of servos and here they are:
- As we have said before, a job may require different motors and sometimes it is not a servo one that can suit the application better. Depending on what you require, you might need a stepper or a pneumatic actuator to make the application work.
- These engines are not as easily repaired and not many manufacturers have proper skills or equipment to fix the problem. Although here you have to consider the fact that servo motors rarely fail in general.
An important decision
A careful research never hurts anyone! Even if the number of advantages is clearly outweighing a few disadvantages it is clever to be aware of them. A thought through decision will ensure the benefits that servo motors are offering to your business.
