SHREDDER DRIVE CONTROL DEVICE AND METHOD OF DRIVINGLY CONTROLLING THE SHREDDER

摘要

A shredder drive control device which shreds sheets of paper by driving a shredding mechanism by a motor capable of increasing the shreddable number o f paper sheets and reducing a shredding time for each shredded paper sheets within the allowable range of an input current, characterized by comprising the motor (4) driving the shredding mechanism (5) for shredding sheets of paper (10) and a control means (1) controlling a power supplied to the motor located between the motor and a commercial power supply (13), wherein the motor has such a characteristic that, when a supplied voltage is used as a parameter, a motor torque generally plummets linearly as a motor speed increases, and the control means lowers the speed of the motor as a torque required for the shredding of the paper sheets loaded on the shredding mechanism increases so as to control a power input from the commercial power supply so that it does not exceed a specified value.
