Drives that control motor speed such as Variable Frequency Drives (VFDs), AC Drives, and Variable Speed Drives (VSDs) include a rectifier unit, in which the AC voltage is supplied to the drive is converted into DC voltage. In most of these motor drives, this rectifier unit makes use of standard P-N junction diodes (two-layer diodes)…
A Variable Frequency Drive (VFD), also known as a Variable-Speed Drive (VSD), Adjustable-Frequency Drive (AFD), Frequency Converter (FC), Adjustable Speed Drive (ASD), Microdrive, AC drive, or an Inverter driver, is an electronic controller used to regulate the rotational speed of induction or synchronous electric motors. The VFD controls motor speed by varying the frequency of…
VFDs or Variable Frequency Drives are controller systems including motors that give varying output speed as per input command. The capacitor forms DC links the whole VFD system. The voltage across this DC link is an important parameter to be controlled. This voltage is input to the inverter and thus acts as a reference voltage…
What Are VFDs? The term VFD stands for Variable Frequency Drive. It is a type of motor controller which drives an electric motor by varying the frequency and voltage supplied to that motor. Variable Frequency Drives (VFDs) are also known as AC Drives, Inverters, Variable/Adjustable Speed Drives, Inverters, Variable-Voltage Drives, Microdrives, Frequency Converters, or Variable…
What Does VFD Stand For? VFD stands for Variable Frequency Drive. It is a type of motor controller that drives an electric AC motor by varying the voltage and frequency of its power supply. By adjusting the frequency of the AC voltage being supplied to the motor, the VFD is able to control the speed…
Modern industries need extremely compact and energy efficient variable frequency drives which ensure future configurability as well. EATON has introduced a variety of variable or adjustable frequency drives that can be used for HVAC, industrial, waste, and water treatment plants, etc. so machines could perform as per requirements. EATON’s SVX series brings about a wide…
