Speed control in industrial drives can serve several purposes. The VFD (variable frequency drive) or VSD (variable speed drive) can control the RPM of a motor which drives a fan, pump, conveyor belt or other machine. The advantage of using speed controls is that the speed of the machine can be matched to the need, can be automatically controlled through feed back loops, and also the VFD/VSD controlled motor will use significantly less energy than a similar system using a bypass loop to bleed energy from the pump or fan system.What is the importance of speed control in industrial drives?kindly elaborate.?
That is a very general question. However, machines that cut metals often must have speed controls whether they use mutliple-speed motors or change gears or variable speed controllers. The cutting tool (perhaps a lathe or drill press or milling machine) creates a great deal of heat at the cutting edge and a cooling liquid must be used to carry the heat away so as not to affect the heat treatment of the metal or shorten the tool life. The cutting speed must be adjusted to match the heat generated with the rate the heat can be removed.
