WEG supplies a complete solution to drive the shredder, one of the most important processes in the production of Pulp & Paper. The drive must be prepared for high inertias and high resistant torques to operate the shredder effectively.
A pony-motor can reduce the impact of drawing power direct from the grid to start the shredder which requires a starting current much higher than the rated current.
Our solution for the power supply of the refiner provides efficiency with the best cost effectiveness. Our CFW11 drive can be configured with two outputs using the same frequency drive for the Pony-Motor and the motor of the screw feeder.
In this application, the motor and drive set is able to operate with constant torque throughout the speed range, in addition to withstanding momentary over speed when required.
