Most of the machines being manufactured today have only two types of motion, radial motion, and linear motion. Linear motion is usually obtained from machine elements with radial motion. For example, a servo motor is a radial motion element, but when used with a ball screw, it converts radial motion to linear motion. Linear slide products are also linear motion elements. However, they often require radial drive equipment to move. But, not all radial motion equipment is intended to create linear motion. For example, the turntable equipment in a milk bottling plant works only to produce radial motion.
If you want to transfer a load from one point to another point in a controlled manner, in a machine, or in a place in your home that needs movement, you need electromechanical products. You can also do this yourself by purchasing mechanical products such as ball screws, belts/pulleys, or racks/pinions and combining them with a stepper motor or servo motor. But putting these products together may require a high degree of mechanical, electronic, and software knowledge. If you want to have a ready-made product, you can use linear actuators produced by many different companies.
With the rapid development of technology, the need for precise and fast production is increasing day by day. To achieve this speed and precision, it is necessary to use advanced technology products in the movement axes of the machines.
Today, the main axis drive systems used in machines are as follows.
1- Belt – Pulley
2- Screw Shaft
Moving the load with the ball screw enabled the machines to be able to position very precisely.
As is known, servo motors are equipment used for precise positioning, and the part that provides precise positioning is the encoder. Motion profiles are performed with the PID control method generally. However, in some cases, the values in the Proportional, Integral, or Derivative definitions that provide the PID are not compatible with the system. This is the main reason why the servo motor buzzes loudly at a stop or while moving. As can be seen in the example in the video below, the servo motor is in the “on” state, but a loud humming sound is heard when it is stationary.
