Electric Motors in Industry
Electric motors are an integral part of many sectors of human activity. They significantly simplify manufacturing processes by replacing manual labor with automated systems that convert electrical energy into mechanical energy. To perform various manufacturing tasks, specific characteristics of electrical machines are required, in particular, the frequency of the motor shaft rotation. Since the speed of rotation for asynchronous and synchronous motors, which are the most common in industry, depends on the frequency of the alternating current, this frequency needs to be adjusted to control the rotor's rotational speed. In such cases, frequency converters are widely used in many fields.
Drilling Rigs
Rotary drilling is one type of rotary drilling, during which the rotation of the drill string is transmitted from the rotary electric motor. During the creation of wells, the drilling tool may pass through various types of rocks, such as clay, gravel, sand, etc. For effective selection of the operating mode of the drilling rig, it is important to consider the rate of destruction, which depends on the pressure created by the drill string, as well as the frequency of the bit's rotation. The volume of liquid intake and discharge also depends on the operating mode of the compressor, where an electric motor is also installed. The regulation of the motors driving both the drill string and the compressor is carried out using frequency regulators.
Machine Tools
Processing various materials requires different operating modes of machine tools, as different materials have different densities and hardness. On conventional machine tools, the speed of the cutting tools is set manually, while on CNC machines, it is automatically controlled by programming. In any case, a frequency converter is used to change the rotation frequency of the rotors of asynchronous motors, providing effective material processing.
mills
The operation of mills, which are used for grinding solid objects, also depends on the density of the processed materials. For the most dense materials, a lower rotation frequency of the cutting tools is chosen, while for less dense, brittle materials - a higher one. Vacuum in the systems is achieved by the operation of fans driven by asynchronous motors. In cases of smoke generation, the speed of the fans can be increased, which will help create a stronger vacuum and provide better smoke removal. The frequency of the operating motor of the unit is regulated by a frequency controller.
Thus, the use of frequency-controlled systems demonstrates its effectiveness in many areas. The ability to adjust the operating modes of equipment with electric motors not only saves electricity but also reduces the wear and tear of other elements in the system.
