mills variable speed drive

Variable speed drives for rolling mills Rolling mills demand high precision and high overload capability. The mill is subjected to rapid change in load speeds, forcing equally quick generating and braking actions. This demands a constant torque in a wide speed May 01, 2002Comparison of high torque--low speed (variable) drives Traditionally, a frequency controlled AC motor or a thyristor controlled DC motor has normally been used in conjunction with a gear box in order to create variable speed. The various types of drive systems that exist on the market all have different characteristics of torque and speed.

This Variable-Speed Mill/Drill is an ideal choice for slow-speed, high-torque requirements in shops operating on a 220V single-phase power supply. By utilizing a built-in Variable Frequency Drive (VFD), a 3-phase motor can be used instead of a single-phase motor, providing variable-speed control and superior torque at slow speeds.

The MV100 3400 HP, a UL certified variable speed drive of the INGEDRIVE ™ range, is integrated in the grinding system of a copper mine in Nevada, USA. In the first quarter of 2020, the commissioning of the medium-voltage variable speed drive for starting up the SAG and ball mills was successfully co

For example, you will find Voith high-performance universal joint shafts in rolling mills on every continent of the earth. The universal joint shafts transmit torques up to 20,000 kNm, are precisely matched to the requirements of the drive and hit the optimal ratio between power, reliability and cost.

These drives offer a motor current up to 720 A, for synchronous or induction motors. Our PowerFlex 6000 drives meet applications that require variable speed motor control from 2.211 kV, with motor current up to 680 A. These easy-to-use drives are well-suited for variable torque applications like simple, standalone centrifugal fans and pumps.

mills. The reliability that translates into greater uptime and profitability begins by specifying and selecting the proper drives for these critical applications. Many variables—such as service fac-tor, gear drive rating, thermal capacity, speed variation and drive ratio—must be considered when sizing and select-ing a gear drive.

The Ferrari Sugar Milltandem in Brazil is fully automated with variable speed for all the drives involved. The mills' rollers are individually moved by electro-hydraulic drives (including the fourth roller in millone), thus offering a great advantage to automate the millin a very accurate way and to also measure the speed

Using variable speed drives (VSDs) in pump applications

Jul 28, 2012Pumps are one of the most common variable speed drive (VSD) system applications and special interest has focused on improving their energy efficiency by using variable speed control instead of throttling or other less efficient flow control methods.. Pumps are the single largest user of electricity in industry in the European Union, consuming 160 TWh per annum of electricity and accounting for

While all variable frequency drives (VFDs) control the speed of an AC induction motor by varying the motor's supplied voltage and frequency of power, they all do not use the same designs in doing so. There are three major VFD designs commonly used today: pulse width modulation (PWM), current source inverter (CSI), and voltage source inverter (VSI).

One possible solution for coal mill capacity increase is analyzed and presented in the paper. It is based on application of MV variable speed drive with increased frequency of motor voltage supply in the range of 50-55Hz. In the paper the thorough
