Shredder with turbo function

摘要

A document shredder with a motor, a cutting unit, and a motor control, wherein the motor control may start, stop and reverse the motor. The motor control may limit the maximally allowed load of the motor to a predetermined load limit value. In case the motor reaches the maximally allowed load limit value, the load limit value may be increased for a predetermined time, either manually or automatically. In this way a short overload does not lead to a paper jam and the shredder does not have to be reversed, which may cause a paper mess in the workplace. The motor may be a direct current motor and/or a series motor, so that the load limit value may be defined by a maximally allowable motor current.
