Frequency inverters

General information

The frequency converter (frequency converter) can reduce the energy consumption of the motor regardless of demand. The use of a frequency converter typically achieves electricity savings because it literally converts a direct current into an alternating current. A frequency converter consists of a rectifier, an intermediate circuit, an inverter and a control circuit. There are two types of frequency converters: current-guided frequency converters and voltage-guided frequency converters. Frequency converters generate a three-phase current with a lower or higher frequency from the mains frequency.

 

 

They allow the engine to operate at the most efficient speed and adjust the engine power to the required level. This prevents overloading of the motor, which can improve overall efficiency and reduce engine operating costs in the long term. The most common electric motors in the industry operate on a 50 Hz AC mains as standard, which in turn limits the speed to a predetermined fixed value.
