    • A shredder includes a shredding mechanism and a vibration sensor configured to detect vibrations generated by the shredding mechanism. The shredder includes a controller configured to regulate operation of the shredder's motor in response to the detected vibrations. The controller may regulate operation of the shredder so as to keep the detected vibrations below a predetermined vibration level during operation of the shredder. The controller may modify operation of the shredder (e.g., turn the shredder off, conduct an autocorrect sequence, increase or decrease the shredder's speed, display an error message) in response to the detected vibrations having a predetermined characteristic (e.g., frequency and/or amplitude within a predetermined range, a characteristic that indicates a material/paper jam or misfeed). The controller may change the predetermined characteristics over the life of the shredder to account for gradual changes to the shredder's baseline vibration characteristics as components wear in and out.
    • 粉碎机包括粉碎机构和被配置为检测由粉碎机构产生的振动的振动传感器。 粉碎机包括控制器,其被配置为响应于检测到的振动来调节粉碎机的电机的操作。 控制器可以调节粉碎机的操作,以便在粉碎机的操作期间将检测到的振动保持在预定的振动水平以下。 响应于具有预定特性的检测到的振动(例如频率和/或频率),控制器可以修改粉碎机的操作(例如,关闭切碎机,进行自动校正序列,增加或减少粉碎机速度,显示错误消息) 振幅在预定范围内,表示材料/卡纸或卡纸的特性)。 控制器可以在粉碎机的寿命期间改变预定特性,以解决当组件磨损和脱落时切碎机的基线振动特性的逐渐变化。
