The present invention relates to an electric apparatus mounted in sliding bearings, said electric apparatus comprising an end N, at which is located a fan, and an end D, at which is located a shaft, and a rotor, one end of which is journalled by means of a first sliding bearing at the end N, and the opposite end of which is journalled by means of a second sliding bearing at the end D, the end N being provided with a first bearing housing with an oil sump for the first sliding bearing, and the end D being provided with a second bearing housing with an oil sump for the second sliding bearing. In order to render the warming up of the sliding bearing at the end D lower than before and to be able to increase the rotational speed of the electric apparatus and/or to be able to operate the electric apparatus in ambient temperatures higher than before, the oil sumps of the end N and the end D of the electric apparatus are interconnected by a passage system, which enables the oil located in the oil sumps to circulate between the end N and the end D.
