To provide an elevator, a door control device, and an elevator door control method that are able to prevent the temperature of a door motor from excessively rising.SOLUTION: A door control device that controls an opening/closing operation 10 of a door 1 is provided. The door control device 10 includes: a door opening/closing control unit 13 that controls torque of a door motor 2; and a closed-end detection switch anomaly determination unit 12 that determines an anomaly in a closed-end detection switch 4, based on a detection signal detected by a closed-end detection switch 4, a signal detected by an encoder 3, and a torque signal of the door motor 2. When the torque of the door motor 2 continues at limit torque for a predetermined time, the closed-end detection switch anomaly determination unit 12 sets the torque of the door motor to standby torque smaller than the limit torque.SELECTED DRAWING: Figure 1

    【課題】ドアモータの温度が過剰に上昇することを防止できるエレベーター、ドア制御装置及びエレベーターのドア制御方法を提供する。【解決手段】ドア1の開閉動作10を制御するドア制御装置を備えている。ドア制御装置10は、ドアモータ2のトルクを制御するドア開閉制御部13と、閉端検出スイッチ4が検出した検出信号及びエンコーダ3が検出した信号、ドアモータ2のトルク信号に基づいて、閉端検出スイッチ4の異常を判定する閉端検出スイッチ異常判定部12と、を有している。そして、閉端検出スイッチ異常判定部12は、ドアモータ2のトルクが制限トルクで所定の時間継続した場合、ドアモータのトルクを制限トルクよりも小さい待機トルクに設定する。【選択図】図1
