The invention provides a winch, a winch system and a state estimation device, wherein the temperature of a motor can be estimated, and the carrying efficiency is high. The winch with the motor controls the motor to raise or lower the hoisting load, and comprises a motor driving signal acquisition part for acquiring a driving signal of the motor, a relation information storage part for storing the relation between the driving signal at a preset time and the temperature of the motor as relation information, and a temperature estimation part, and a motor temperature estimation unit that estimates the motor temperature on the basis of the motor drive signal at the time acquired from the motor drive signal acquisition unit and the relationship information during the operation of raising or lowering.

    本发明提供一种能够推算电动机温度并且搬运效率高的卷扬机、卷扬机系统和状态推算装置。本发明的具有电动机的卷扬机,控制电动机来进行吊重的起升或下降,其包括获取电动机的驱动信号的电动机驱动信号获取部、将事先规定的时刻的驱动信号与电动机温度的关系作为关系信息保存的关系信息存储部、和温度推算部,其在起升或下降的运行的过程中,根据从电动机驱动信号获取部获取的时刻的电动机驱动信号和关系信息来推算电动机温度。
