Thank you for all your posts.
Let me clarify my question: I do need to find a better solution (motor + drive) for the new cooling fan meeting the following three requirements: start up the fan smoothly, realize the speed of the fan variable in 50-100% range with accuracy around 2% of the...
I am working on a cooling fan for cement kiln, the motor is 1600KW with speed variable in 50-100% range. VFD is not considered because of the cost. A squirrel cage motor and fluid coupling drive is preferred at this moment. Is there any better solution for this application? Thanks a lot.
The metal type resistive controller for WRIM is more reliable than liquid rheostat starters. The controller consists of only three durable parts: stainless steel resistors, vacuum contactors and PLC. It’s reliable and maintenance free. PLC controls contactor close/open to switch resistor in/out...
