Frequency inverters, also name as variable frequency drives, variable speed drives, inverter drives, AC drives, are used in electro-mechanical drive systems to control AC motor speed and torque by varying motor input frequency & voltage. Many fixed speed motor load applications that are supplied direct from AC power supply can save energy when they are operated at variable speed by means of frequency inverters. Such energy cost savings are especially pronounced in variable torque centrifugal fan and pump applications. Inverter.com offers universal frequency inverters, single phase input and output frequency inverter, 1-phase to 3-phase frequency inverter and three phase frequency inverter, widely used in various loads.
