People realize that the common hydraulic motors today aren’t cutting it anymore. They can be expensive, cause oil problems, and occasionally leak.
But luckily there’s a better option out there.
Electric servo motors and drives have been evolving for some time now. And they seem to be great for all different industries. That’s why we’ve gathered the top 5 advantages of servo systems to show you exactly how great they really are.
Speed of Servo Motors and Drives
Many people debate the speed and acceleration of servo motors and drives compared to those of hydraulics. The truth of the matter is that hydraulics aren’t the fastest because of its compressions of oil and flexibility of its hoses and lines that expand.
If hydraulic systems were designed better, then the speed may be better and closer to that of a servo system. But for the time being servo motors and drives are more impressive in the category.
Versatility
The next advantage of these systems is the versatility servo technology. They can be used for so much, and there are different kinds as well.
Usage
Servo motors are in a wide range of machines.
Inside of a servo system is a motor that toys also often come with. This motor is called a small direct current motor, and it runs on electricity from a battery.
They are also in cameras. Specifically, in it’s Auto Focus to help the camera’s lens sharpen images. Automatic door openers also use the motor to help signal it to open.
Another use of this system is the robotic arm that helps move along assembly lines. The servo motor helps make the joints of the robotic arms move.
Types
The servo motors in the servo system come in many different forms.
- Positional- this is the most common and can rotate in certain directions.
- Continuous- this one is similar to positional but can rotate in all directions.
- Linear- this one has the features of the previous ones but has additional gears.
Something that varies in the different types is how they are used as well and their availability. The positional servo motor can be found in smaller applications, while the continuous and linear motors are geared towards larger projects.
Exerts Less Heat
Hydraulic machines let out a large amount of heat. This is mainly through its work with oil and overall design of the machine.
Servo motors and drives release such a small amount of heat. So small in fact, that operators usually need to employ another system that keeps the oil at temperature.
Service of Pumps
Another large difference between hydraulic machines and servo motors and drives is maintenance.
While hydraulic machines are generally cheaper to buy the servo systems will give you your money’s worth in how much it saves, as well as cut down costs on maintenance.
Hydraulic machines will need to be serviced often as their pumps will need to be changed. And their pumps are also more expensive than those of a servo system.
Simplicity
Servo motors and drives are also extremely simple machines. This makes work and maintenance a lot easier to carry out.
An all-electric motor will have fewer parts than those that are hydraulic-based. As a result, an electrician will be able to work on it without needing hydraulic knowledge.
These servo systems also use technology that will make repairs easier. They use feedback devices that help catch errors and correct them to help better performance.
