The electric motor has seen an important expansion in the last decade, in multiple applications such as: automotive, e-mobility, industrial automation, agriculture and several industrial sectors, in order to make the industry more sustainable. In conjunction with the electric motor evolution, it has been necessary to provide motor control systems increasingly efficient. In this optic, it has been realized a motor control system to facilitate and improve the analysis and study of an asynchronous motor. The development system is composed of an electrical cabinet with all the most important safety components, a three-phase inverter and a communication method to make simple the interface between the final user and the machine. In particular, the electrical panel design has been developed in order to realize a safety structure able to accommodate the inverter and the relative components for controlling the asynchronous motor. The adopted inverter is the ES350-F0-4K0G-3B model provided by the Cumark company. This device implements the overall drive for the motor control, starting from the AC-DC power supply stage converter, passing through the logic control, to end with the inverter power module to drive the motor. Finally, to realize a user-friendly interface with the motor, a graphic user interface (GUI) has been designed. The GUI has been developed with MATLAB environment, and it implements the serial communication between the inverter and the PC, through Modbus RTU protocol, common industrial robust system. This solution allows to realize a speed control system to manage the motor in remote mode, in particular the GUI control panel has been focused on the setting of the speed reference and of the acceleration and deceleration time for adjusting the speed variations, moreover it provides the monitoring of the voltage and the frequency behaviour, and the main drive information.
