Siemens VFD Drives: Energy-Efficient and Precision Control
What are VFD Drives? VFD Drives are called Variable Frequency Drives (VFDs), and they're the most sophisticated apparatus designed to control both speed and torque of electric motors by varying the frequency and input voltage. They are commonly used, and in their place, come energy performance, motor lifetime enhancements, and better control of motor operations. How Do VFD Drives Work? VFDs are fundamentally made of three components, namely: Rectifier: which actually converts the AC power source into DC. DC Bus: which serves to filter and store DC energy. Inverter: which will reconvert the DC back to a variable AC power with the ability to adjust both frequency and voltage. VFDs in simple terms control the frequency with which an electric motor operates and so help speed control of the motors, thus making them the right choice when it comes to the dynamic requirements of the industry.
