Which motor is used in paper mill

Paper mills use specialist machines equipped with large DC motors to produce pulp from raw material, convert pulp to paper, wind to reel and post-produce by slitting, coating, printing and packaging.

Which motor is used in rolling mill?

1. DC Series Motor. Since it has high starting torque and variable speed, it is used for heavy duty applications such as electric locomotives, steel rolling mills, hoists, lifts and cranes.

Which motor is preferred for grinders of paper mill?

The grinders require a very large power and low speed. For such operation, synchronous motors are useful. Geared drives may be used for reduction in speed. A cycloconverter fed synchronous motor can be operated at low speeds and the gears can be completely dispensed with.

Which drive is used in paper mill?

Dc adjustable voltage drives. Because of the dc drive’s ability to provide constant torque over its entire speed range, it has been the electric drive of choice for paper machines and other equipment that require wide constant torque operation.
