摘要:
Provided is a rotating electrical machine, including: temperature information acquisition means for acquiring information on a temperature of a brush; rotation information acquisition means for acquiring information on a rotation angle of a rotation shaft; and a wear amount calculation section for acquiring the temperature of the brush based on temperature information including output information of the temperature information acquisition means, and for calculating a total wear amount of the brush by integrating a product of a value corresponding to the temperature of the brush, the value being a wear amount function defined as a wear amount per unit sliding distance of the brush with the temperature of the brush used as a variable, and a value including an rotational speed of a rotor, with respect to time from immediately after start of use of the brush to a current time.
