It is generally used to control asynchronous motor cycles. Speed control of an asynchronous motor can be done in two different ways.
1- By changing the number of poles
2- By changing the motor feeding energy frequency
Unless double speed motor is used; Since it is impossible to change the number of poles of the motor in the installation, motor speed control can be done by changing the supply frequency. At this point, you need to include frequency inverters in your project. The motor speed with frequency inverters; It is possible to control the speed by keeping the motor at the desired point between the lowest and highest revolutions.
In frequency inverters; overload, over current, under and over-voltage, over-temperature, short circuit etc. there are protections. Frequency inverters; It corrects the mains voltages, absorbs, filters and cleans all voltage fluctuations, peaks, damaging electric currents that occur in the network with the help of capacitors and coils in hardware mechanisms.
Besides, as long as an emergency stop device is installed on the frequency inverter and appropriate equipment is prepared, your device can protect itself and your motor in any actionable situation that may occur in the system.
Today, many inverters are now manufactured with PLC functionality. Thanks to these smart applications of inverters, you can dance your asynchronous motor as you wish, and you can do many numerous applications such as PID method and MASTER-SLAVE with inverters.
Considering the sensitivity of the product carried by frequency inverters; With its soft start and soft stop feature, adjustable ramp times, follow-up of the instantaneous current-voltage-frequency curves of the motor, anti-sway, anti-grab and speed control according to the load if PLC hardware is added, instantaneous error codes, motor recognition features and with quality,It has become an indispensable part of Arnikon Engineering and Crane Systems.
As Arnikon Engineering and Crane Systems, we support frequency inverters to comply with new generation technology and quality standards; Considering the environmental conditions and occupational safety of the project site where the crane will be installed, we would like to state that it is the number one product of our electrical equipment group.
In line with our ongoing R&D studies in the smart crane sector, we adopted the PLC-Frequency Inverter-Motor and Frequency Inverter-Motor equipment as a company, and we used Frequency Inverter and Motor controls in all of our standard cranes; In our specially designed smart cranes; We make Frequency Inverter-Motor controls with PLC.
