Hello everyone, I am Rose. Today I will introduce VFD to you. A variable frequency drive (VFD) is a power control device that uses power electrical technology to adjust the motor's operating power frequency and hence control the motor's speed. ...
in literature: VFD (variable frequency drive) ASD (adjustable speed drive) VSI (voltage source inverter) CSI (current source inverter) Here is a brief explanation of some of the commonly used terms used in conjunction with variable frequency drives: Frequency converters to convert the ...
The basic function of a variable speed drive (VSD) is to control the flow of energy from the mains to the process.
A "Variable frequency drive" (VFD) is a motor drive system that controls the motor by altering the frequency. For AC machines, the frequency is directly linked to the rotation speed of the machine. Although this term is still widely used in reference to industrial drives, it is somewhat red...
Avariable speed drive(VSD) is any drive that can control the speed of a piece of equipment, including both AC and DC motors. VSDs can operate via mechanical, hydraulic, or electrical means. Avariable frequency drive(VFD) is used to control the speed ofAC motors,and does so by varying th...
