Abstract
An electrical apparatus mounting a motor includes a controller and an electrically data rewritable non-volatile storage. The controller is configured to execute: a temperature calculation process in which in a case that a state of the motor is switched from a driven state to a stopped state, the controller calculates a temperature of the motor based on rotation of the motor; and a temperature storing process in which the controller stores, in the storage, the temperature, which has been calculated at the time of the switch operation in the temperature calculation process, as a peak temperature, together with an absolute time clocked at the time of the switch operation.
