　　 Variable frequency drive

　　A variable frequency drive (VFD) is an electronic device used to control the speed of AC motors. Background: When an electric motor or AC motor is directly powered by an AC voltage supply, it can only operate at a fixed speed determined by the number of poles in the power system and the supply frequency. However, if an application or production process requires adjustable AC voltage—and thus controllable speed—a VFD is employed. Such drives can generate an AC output voltage whose amplitude (output voltage level) and frequency are both variable, even when supplied with a constant AC voltage.

　　 Inverter operation

　　Therefore, the variable frequency drive is connected upstream of the motor to generate an AC voltage that can be adjusted to meet customer requirements. As a result, the power supply system no longer produces the motor’s operating frequency and voltage levels. Instead, the VFD assumes this responsibility and controls both the output frequency and output voltage.

　　What are the main advantages of a variable frequency drive? It allows you to seamlessly adjust the motor speed from nearly zero up to its rated speed, with a wide speed range. The motor’s torque remains constant. As a result, plant operators can readily adapt the drive system to meet changing operational requirements. Additionally, a VFD enables direct reversal of rotation direction; a single control command is sufficient to change the phase sequence, causing the downstream AC motor to rotate in the opposite direction.

　　 Type of inverter

　　 There are two types of inverters:

Current-controlled and voltage-controlled types. Their functions differ. Current‑controlled inverters maintain a constant current‑to‑frequency (I/f) ratio, making them suitable for high‑megawatt‑range applications.

　　Conversely, in the lower megawatt or kilowatt range, voltage‑controlled inverters represent cutting‑edge technology. They consistently maintain a constant voltage‑to‑frequency ratio; thus, if a motor rated at 230 V and 50 Hz is operated at 25 Hz, the voltage will likewise be halved to 115 V.

　　In simple terms, the following applies to voltage‑controlled inverters: The rectifier converts the AC voltage supplied by the power system into DC voltage. The DC link then smooths and stabilizes this DC voltage. Next, the motor‑side DC‑to‑AC inverter generates an AC voltage at the output frequency required by the application. The resulting voltage frequency determines the desired motor speed. An integrated controller, which interconnects all components, sets or calculates the required speed.

　　 Where is it used?

　　Variable frequency drives are used across a wide range of industrial sectors and applications. Whether powering pumps and fans, machining equipment, conveyor belts, or assembly lines, or driving cranes and material-handling systems, VFDs have become indispensable in modern industrial production. In these applications, adjustable or stepless speed control optimizes manufacturing processes, while speed‑controlled drives also help ensure energy‑efficient operation.

　　 Variable frequency drives suitable for a wide range of equipment and machinery.

　　Our inverters come in various designs and offer a wide range of optional features to meet diverse needs and requirements. Another critical consideration is whether the inverter should be mounted on a wall, installed in a protected central location within a control cabinet, or directly on-site (i.e., at a distributed location). Furthermore, depending on the simplicity or scale of the application, an increasing number of basic…   Variable frequency drives, or applications employing variable frequency drives (with a broad range of functions or multi-axis servo drives), have been put into operation.
