The present invention relates to a dynamic torque diagnostic device for a winch brake and a dynamic torque diagnostic method for a winch brake, which can detect a dynamic torque through software without adding a new device for monitoring the dynamic torque, and can periodically perform automatic measurement without applying a load to an elevator device. When there is no user in the car, the car is held by the brake, and in this state, a winch torque is applied in the direction of the balance weight to implement a low-speed travel control, and the winch torque when the winch rotates beyond the static holding torque of the brake is detected. The dynamic torque of the hoist is calculated by adding the detected hoist torque to a balance torque that compensates for the load imbalance, and the braking force of the hoist brake is diagnosed on the basis of whether the calculated dynamic torque exceeds a reference value.

    本发明涉及卷扬机制动器的动态扭矩诊断装置以及卷扬机制动器的动态扭矩诊断方法,不附加动态扭矩监视用的新设备就能够通过软件来检测动态扭矩,能够不对电梯设备施加负荷而定期地进行自动测定。在轿厢内没有利用者时,通过制动器保持轿厢,在该状态下向平衡配重方向施加卷扬机扭矩而实施微速行驶控制,检测卷扬机超过制动器的静态保持扭矩地进行了旋转时的卷扬机扭矩,对检测出的卷扬机扭矩加上对载荷不平衡进行补偿的平衡扭矩来计算卷扬机的动态扭矩,根据计算出的动态扭矩是否超过基准值来诊断卷扬机制动器的制动力。
