Provided is an abnormality detection device for an elevator capable of more reliably detecting an abnormality. An abnormality detection device for an elevator is provided with: a current detection unit that detects a current flowing through a hoist of the elevator; a rotation detection unit that detects the state of a rotating body that is a transmission mechanism unit for transmitting the driving torque of the car of the elevator; an estimation unit that estimates a non-inertial torque of a rotating body, which is a subject of the abnormality determination, on the basis of a detection result of the current detection unit and a detection result of the rotation detection unit; and a determination unit that determines an abnormality of the elevator on the basis of the non-inertial torque estimated by the estimation unit.
提供一种能够更可靠地检测异常的电梯的异常检测装置。电梯的异常检测装置具备:电流检测部,其检测流过电梯的曳引机的电流;旋转检测部,其检测旋转体的状态,该旋转体是用于传递所述电梯的轿厢的驱动转矩的传递机构部;估计部,其基于所述电流检测部的检测结果和所述旋转检测部的检测结果来估计作为所述异常判定的对象的旋转体的非惯性转矩;以及判定部,其基于由所述估计部估计出的非惯性转矩来判定所述电梯的异常。
