DC Motors Designed for Your Application DC Motor Applications TECOWestinghouse Motor Company DC motors are ideally suited to a multitude of industrial and marine applications in which high torque and variable speed are required. These applications include ship propulsion, mine hoists and steel rolling mills. They also drive many other types of
Rolling mill drives, cement mill drives, paper mill dries and textile mill drives. HOW TO SCORE GOOD MARKS IN VTU EXAMS: FOLLOW DUBEY TEXTBOOK, The University question papers set by following the same book, For Unit8, Follow the following material and also just check previous questions and solutions from following material links below.
#0183;#32;A typical drive for a continuous mill producing steel rod would be rated at 500 kW per stand and having a dynamic response such that the speed deviation on application of full load would be less than 1% and the recovery time of the order of 100 milliseconds.
Application of DC Compound motor By compound motor, we get high starting torque and nearly constant speed. Because of that Compound motors are used where we require high starting torque and constant speed. A compound motor is used in Presses, Shears, Conveyors, Elevators, Rolling Mills, Heavy Planners, etc. Why motors are used?
Siemens Large Drives Applications engineers and produces heavyduty electrical drive systems for medium and high voltage ranges: electrical motors, converters and generators. Additionally we offer special large drives for ships, mines and rolling mills. Our digitalization expertise and outstanding service keeps the performance and availability of your drives always at the maximum.
#0183;#32;Applications of DC Motors. Elevators, Rolling Mills, Heavy Planners, etc. The small DC machines whose ratings are in fractional kilowatt are mainly used as control device such in techno generators for speed sensing and in servo motors for positioning and tracking.
#0183;#32; APPLICATIONS OF CONTROLLED DRIVES J. McTaggart, Divisional Chief Engineer, Systems Design Division, GEC Electrical Projects Limited, Rugby, SUMMARY Controlled drives are very widely applied in ratings from less than 1 kW up to 10,000 kW or more.
#0183;#32;Based on the above information it is possible to decide the requirements of a drive motor to suit a given appli#173;cation. Of the numerous industrial applications in which electric motors are employed as drive motors, only a few are discussed here: 1. Textile mills. 2. Steel rolling mills
The DC motor drive also provides the high current torque, 400 % more than the rated continuous torque. The important applications of DC motor drives are rolling mills, paper mills, mine winders, hoists, machine tools, traction, presses, textile mills, excavators and crane.
Raymond is quite right. However, Id like to add that often large induction machines are used with variable frequency drives (VFDs) these days, they have similar speed control, smaller footprint and lower operating costs than machines with slip ri...
Optimizing DC drive Bar rolling application Optimizing DC drive Bar rolling application mash98 (Electrical) (OP) 17 Mar 13 00:32. We have a bar rolling mill where a dc motor of following specs is being used while the drive for the same is Mentor II (M1850). General Electric Direct current motor No. Type MCF HP 1250
Rolling mill DC motors are best at low speed, high torque applications, while AC motors typically need to run above 800 rpm to be cost effective. To handle this most drive manufacturers offer

A dc motor and drive configuration was the only variable speed motor option for a long time and the components are developed and proven. Even now, dc motors are popular in variable speed, fractional horsepower applications and are useful in lowspeed applications because they can provide full torque at low speed and constant torque across a wide range of industrial motor speeds.
