What is the difference between Variable Speed Drive and Variable Frequency Drive?
A variable frequency drive (VFD) refers to AC drives only and a variable speed drive (VSD) refers to either AC Drives or DC Drives. VFD's vary the speed of an AC motor by varying the frequency to the motor. VSD's referring to DC motors vary the speed by varying the voltage to the motor.
The factor that may change in response to the manipulated variable?
Dependant Veriable. :)
How rectenna works?
It is an antenna tuned to receive microwave energy and with a diode fitted to rectify the microwave frequency to produce DC current.
How does a forensic data recovery hard drive work?
A forensic data recovery hard drive works by utilizing specialized software and hardware to extract and retrieve data from damaged or inaccessible storage devices, such as hard drives, solid-state drives, or USB drives. It bypasses the file system and directly scans the drive at the binary level to recover fragmented or deleted files. The recovered data is then reconstructed and made accessible to the user for analysis or investigation purposes.
Can a glass prism separate white into different colors?
Yes. The reason this works is because the index of refraction varies depending on the frequency (or wavelength) of the light.
What is meant by VFD?
A variable-frequency drive (VFD) is a system for controlling the speed of a rotational or linear alternating current (AC) electric motor by controlling the frequency of the electrical power supplied to the motor.[1][2][3] A variable frequency drive is a specific type of adjustable-speed drive. Variable-frequency drives are also known as adjustable-frequency drives (AFD), variable-speed drives (VSD), AC drives, microdrives or inverter drives.
What are some of the leading brands in variable frequency drives?
Many companies sell variable frequency drives. ABB, GE, Eaton, Baldor, AC Tech, Honeywell, Toshiba, IDM, Hitachi, and Yaskawa are major brands that sell variable frequency drives.
Need of drives in motor?
Drives - I assume you are referring to Variable frequency Drives. The drives are useful when a motor needs to rotate at different speeds when in operation with out stopping it.
What is a veriable?
Something that varies or is prone to variation.
What is independent veriable?
a variable that is changed in a experiment.
Where to find the best Variable frequency drives?
There are various types and make of variable frequency drives available commercially. You need to define your requirement first. Basis your requirement and budget you can choose most suitable one from market.
Does VFD provide a solution to energy crisis?
Variable frequency drives help in conserving atleast 35% of the energy used by a motor!!! Variable frequency drives help in conserving atleast 35% of the energy used by a motor!!!

What does the command scandisk do?
Scandisc only works on hard disks and floppies, not on tape drives, CD-ROM drives, or DVD-ROM drives.
How does a frequency drive work?
Frequency drives are an adjustable-speed drive used for electro-mechanical drive systems. They control the motor speed and torque by varying motor input frequency and voltage.
The factor that may change in response to the manipulated variable?
Dependant Veriable. :)
How does MFM work on floppy disks?
MFM is modified frequency modulation and it works on floppy discs to encode the data. It is now becoming an obsolete system since DVDs and flash drives hold so much more data.
