Abstract:
Variable Frequency Drive (VFD) refers to an adjustable-speed drive where alternating current electric motor can be controlled by changing the values of frequency and voltage. This process allows the motor to change its torque and speed, depending on the need or demand from the user. VFD is used in many different applications, ranging from small to big, while preserving all other relevant advantages. Some of these advantages that come with using VFD are better process control and regulation, extended equipment life, and reduced maintenance. The components of VFD are converter, DC bus, and inverter. We successfully integrated VFD with Programmable Logic Controller (PLC) using sequencer Instruction to have a complete control over the AC servomotor, and operate motor with change in frequency of VFD. In this poster, we will examine what VFDs are and their applications. The outcome has market demand, especially that VFD applications contribute significantly to different industries.
