· For example at a coal fired power plant in the United States a 7000 hp motor was running with only 7 percent overcurrent but an 8 percent overvoltage Two identical applications had undergone unscheduled outages in the previous 12 months A mild overload was identified by examining the stator current of this motor However after looking at the true load
The mill is driven by a direct coupled motor through a speed reducer and final single helical gear set having the driven gear mounted on the mill barrel Figure I shows the application of a ball mill in a typical direct fired coal system These systems can be design ed with or without crusher/ dryers depending on the coal characteristics Use of crusher/dryers in tandem with
The combination of a VFD and motor can provide great advantage for starting a high inertia fan load or to generate the high starting torque required in the starting of a kiln a crusher or a loaded conveyor In the specific case of a kiln application the motors can also be designed with a VFD to provide 200% 250% starting torque or even higher These motor and drive systems

Industrial Automation VFD In Jaw Crusher Applicatoin 2022/11/22 Crusher sites are often dusty so ensure a good enclosure of higher IP rating Check whether the motor is of inverter duty or not always keep an eye on motor temperature If supply for VFD is from Diesel Generator then verify whether the diesel generator is sized so that its able to meet all the peak load conditions
· But the rate at which the VFD is trying to decelerate that motor is faster than the motor will actually slow down because of the inertia The VFD is therefore applying energy to the windings which keeps the magnetic fields active but the applied frequerncy is now lower than the motor s virtual frequency and the motor becomes an induction generator The energy from it
