发明名称 IN-RUSH CURRENT JAM PROOF SENSOR CONTROL
摘要 A shredder and a method for monitoring a motor of a shredder comprises a housing having a throat for receiving an article and a shredder mechanism received in the housing for shredding the article, the mechanism including an electrically powered motor and cutter elements, and the motor being operable to drive the cutter elements in a shredding direction to shred articles. A current sensor for detecting current flowing through the motor and a controller coupled to the motor for controlling operation of the motor are also provided. The controller is also coupled to the current sensor and configured to detect at least an initial amount of current (or inrush current) supplied to the motor for each shredding event. Based on the inrush current, the controller sets a parameter (e.g., overload or thickness) to prevent overloading or stalling of the motor, such as caused by a jam or overheating.
