This week's topic in the blog posts we prepare every week as Şahin Rulman will be industrial servo motors. Throughout the article, we will answer your frequently asked questions such as 'What is an industrial servo motor?', 'How is industrial servo motor control achieved?' and 'How much are the prices of industrial servo motors?' In addition, we will share the necessary information about industrial servo motor types. We hope it will be a useful article for you and we wish you a pleasant reading.
What is an Industrial Servo Motor?
Industrial servo motors, also called control motors, are electric motors developed to control the output movement in feedback control systems. It prevents sudden problems within the system. Thanks to its feedback, it reports errors in the system and allows them to be corrected.Industrial Servo Motor Control
Industrial servo motors have encoders connected to the shafts. Control of industrial servo motors is provided through these encoders. Movement details determined by the user are introduced to the data in the system via encoders. In order for this data to be processed and the servo motor activated in that direction, encoders send signal data and provide feedback. Thus, the user has full control over industrial servo motors via the encoder.Industrial Servo Motor Types
There are industrial servo motor types that stand out with different qualities for different purposes. The best choice among these varieties varies depending on the person and their purpose. That's why we'll cover the general characteristics of each variety here and try to help you decide which one is best for you. Industrial servo motors are divided into 2 types:Industrial AC Servo Motors
It stands for alternating current industrial servo motors. They were developed as an alternative to DC industrial servo motors. As a matter of fact, while DC industrial servo motors are used in applications requiring high power; AC industrial servo motors can be used in applications where both low and high power are needed. Another prominent feature of these engines is their low inertia level, thanks to their simple structure. It does not exhibit linear characteristics as in DC motors. In addition, torque-speed characteristics are inferior to DC motors.Industrial DC Servo Motors
The meaning of this type of motor is direct current. Its name comes from the fact that it contains a DC motor inside the motor. In the early days of industrial servo motors, DC motors were mostly used. The most important parts of this type of motor include the DC motor, control circuit and potentiometer. There is a total range of movement of 180 degrees. DC industrial servo motors are also known as brushless. In this way, the need for extra maintenance is prevented. On the other hand, we can state that DC industrial servo motors also include feedback units.Where are Industrial Servo Motors Used?
The usage areas of industrial servo motors are very wide. It is used in many small and large scale applications. Industrial servo motors are of great importance, especially in applications that require high control precision. Robotic systems, CNC machines, medical devices, production machines are just a few of the dozens of areas where industrial servo motors can be used.Industrial Servo Motor Control Systems
The most important feature that distinguishes industrial servo motors from other motors is that they are designed to fulfill wide speed commands. Servo motor drivers complete their work by fulfilling the position and speed combination commands received from the user. There are certain features that an industrial servo motor that complies with standards must have. These; A servo motor should not lose its stability when changing speed rates and should obtain large moments from small force values. It should change the speeds quickly during operation. It is possible to obtain high efficiency during our work from a servo motor that complies with standard values.When we look at the internal structure of servo motors, they consist of a feedback unit and a motor. The use of DC servo motors is quite common in industrial servo motors, which are divided into two as AC and DC, but we can say that with the increasing ability of transistors to control high currents, the demand for AC motors has increased instead of DC motors. In order to carry out speed and position information between the feedback and the motor, the feedback unit must be connected to the motor shaft with an external connection and the signals sent by the motor must be processed.
In servo motor control systems, the feedback unit and the motor are integrated. Since they are in a complete structure, they can be said to be engines with the necessary equipment for speed and position. Servo motors can operate without overheating even in a wide speed range and provide the necessary torque values to keep the load and its position in balance.
When servo motors operate at full load, the power drawn from the motor shaft reaches 75kw. Servo motors, whose feeding operations are carried out on electronic systems, are available in two different types: brushed and brushless. While the rotation of the magnetic field of the coils is brushless servo motors, the rotation of the magnetic field and the rotation of the coil are brushed servo motors.
Things to Consider When Choosing an Industrial Servo Motor
When choosing an industrial servo motor for your applications that require high motion precision, you should first decide which type is suitable for your work area. Then, it would be beneficial to comparatively examine the features of the engine types in the category suitable for you. As a result, you should choose the product that is most suitable for you in terms of price-benefit balance. The main features of industrial servo motors that need specific attention can be listed as follows:• Torque of the motor Torque of the motor
• Engine power level
• How many revolutions per minute does it make on average?
• What is the flange size of the engine?
• Whether the price level is reasonable according to its characteristics
Factors Affecting Industrial Servo Motor Efficiency
After choosing the right industrial servo motor for your business, we will explain in this section what you need to do to increase the efficiency of the industrial servo motor model you will use. In industrial applications where servo motors are used, work must proceed quickly and uninterruptedly. Since the desired working capacity and application models are not the same in every project, the selection of the technical specifications of the industrial servo motor is the first factor that affects the efficiency you will get. The technical specifications of the servo motor, such as power, torque, speed and flange measurement values, vary. Power selection must be made by taking into account speed requirements and performance in your project or in the area where you will use the industrial servo motor. Servo motors powered by electrical energy have a minimum power of 400 watts and a maximum power value of 5500 watts.In order to get the desired efficiency from the servo motor, you must consider the load demand value, motor deviation values and lifting and lowering intervals. If you choose a low-value industrial servo motor model in a project that requires high working capacity, this will cause the motor to overheat during operation and reduce the efficiency. We can also say that it will affect the speed of work. After selecting the technical specifications of the servo motor, it is necessary to select the appropriate servo motor driver. Operations and adjustments are made with the servo motor driver suitable for the model and brand of the motor.
