Inverters are power equipment used to regulate the speed of asynchronous motors. Speed variation is achieved by varying the motor drive voltage and the frequency maintaining the V/f ratio constant over the entire speed range of the motor. The application range of inverters is very wide starting from simple speed regulation of conveyor belts to speed regulation of fans, flow control of pumps, lifting systems control and synchronization of motors. Inverters are available for powers from a few kW up to thousands of kW and integrate network and diagnostic capabilities to better control performance and increase productivity; the inverter is sized according to the motor power and application. Tekna Automazione e Controllo applies and integrates inverters from the world’s leading manufacturers within Automation systems.
The SINAMICS G120 frequency converter is ideal for precise and economical speed and torque control of three-phase asynchronous motors. The modular structure of the components and the wide power range from 0.55 to 250 kW, ensures the possibility of assembling the perfect converter for any application or industrial sector.
SINAMICS G120 is in fact a modular converter system essentially made up of two functional units: the Control Unit (CU), which commands and monitors the inverter, and the Power Module (PM), which must be chosen according to the power of the motor to be driven.
