What Is a Drive Inverter?
Introduction to Drive Inverters
A drive inverter, also known as an adjustable speed drive (ASD), is a type of electrical device that converts fixed-frequency AC (alternating current) power into a variable-frequency AC power. This variable-frequency power is then used to control the speed of an electric motor, allowing for precise control over the motor’s speed and torque.
Drive inverters are widely used in industrial, commercial, and residential applications, including pumps, fans, compressors, conveyor belts, and more.
