Frequency inverters to control any type of AC motor | Goveco

A Frequency Inverter, often referred to as a Variable Frequency Drive (VFD), is an electronic device that precisely controls the rotational speed of an AC motor by varying the electrical frequency and voltage supplied to it. This sophisticated control is essential for fans, pumps, and compressors in modern HVAC applications. VFDs utilize solid-state electronics to convert incoming fixed-frequency power into a variable-frequency output. By precisely controlling the motor speed, they ensure the equipment's output exactly matches the system's real-time demand, maximizing system response and reliability far beyond simple on/off control. These devices are critical components for achieving energy efficiency in commercial and industrial settings. The power consumption of a fan or pump decreases exponentially with reduced speed, meaning VFDs can provide immense energy savings while simultaneously reducing noise levels and extending the lifespan of mechanical equipment by preventing harsh start-up surges.
