May 18, 2018· Ward Leonard dc drive, ac commutator motors are employed. The thyristor control may be used where efficient, smooth speed control over a wide range is required. Special design of textile mill motors are required owing to the location of the motor, running conditions and also the torque requirements while starting.

Mar 09, 2018· Here are some applications of DC motor in different Forms, Series Motors The series DC motors are used where high starting torque is required, and variations in speed are possible. For example – the series motors are used in Traction system, Crane...

ABB DRIVES AND CONTROL SYSTEM FOR HOT FLAT . A few examples of such standardized appliion modules are shown in Fig. 8 and 9. Page 6 of 14 . Figure 10 illustrates the history of speed controlled drives for large rolling mill drives where DCmotors was used until the beginning of the eighties when the introduction of the (Rolling Mill Drive) control, which replaces the

AC adjustable speed motor drive systems are the preferred technology for new rolling mill installations and modernization projects. TMEIC designs and manufactures two types of AC solutions for this purpose. Salient pole synchronous motors that meet the high power and torque demands of a hot strip mill, as well as roughing and finishing stands.

Selfcontrolled synchronous motor drive employing load commutated thruster inverter. Link: Unit 7 Notes —————————— UNIT – 8 INDUSTRIAL DRIVES: Rolling mill drives, cement mill drives, paper mill dries and textile mill drives. Link: Unit 8 Notes

Each rolling stand is driven by a DC motor, which is equipped with a speed controller. Usually the two DC motors are separately controlled; each servo drive acts only on its motor, by ...

Jul 20, 2016· Dc drives o DC drives have been used successfully in rolling mill applications for many years o Rolling mill DC motors are best at low speed, high torque application. o easy to operate compact o Superior functionality o Efficient power output 8.

III. AC DRIVE FOR ROLLING STAND MOTOR AC synchronous motors are used for driving the roughing stand rolls in a rolling mill. Synchronous motors are used when power requirement is very high and speed of rolling is low. The R0/V0 stand motors of Hot Strip Mill of Rourkela Steel Plant are synchronous motor. These motors are driven by cyclo converter.

ABB has provided DC motors, drive products and systems for more than 120 years to customers in different industries. ABB''s vast experience in DC technology, combined with its long experience in the metals industry results in innovative drive solutions with superior performance, less maintenance, high mechanical adaptability and reliability.

Application areas Lift and cable car drives Rolling mill drives and winders Lifting and running gear drives for cranes ...

Small DC motors are used in tools, toys, and appliances. The universal motor can operate on direct current but is a lightweight brushed motor used for portable power tools and appliances. Larger DC motors are currently used in propulsion of electric vehicles, elevator and hoists, and in drives for steel rolling mills.

7. Slip Ring Induction Motor. It has high starting torque and large overload capacity. The speed of slip ring induction motor can be changed up to 50% of its normal speed. Slip ring induction motor is used for those industrial drives which require high starting torque and speed control such as lifts, pumps, winding machines, presses, line shafts, elevators and compressors etc.

This paper proposes the novel idea of eliminating the frontend converters used indirect current (DC) bus voltage variation, thereby allowing for control of the speed of the brushless direct current (BLDC) motors in the twoquadrant operation of a permanent magnet brushless direct current (PMBLDC) motor, which is required for multiple bidirectional hot roughing steel rolling mills. The first ...
