FIELD: electric machine engineering. SUBSTANCE: this invention relates to A C electric machines. Electric machine includes horizontal shaft with rotor. Bearings are installed in air gap. All parts of bearings are manufactured from high-resistance nonmagnetic materials. Arrangement with two bearings installed on edges of magnetic core of stator is also possible as well as arrangement with additional bearing mounted in center of plane of mass of rotor. EFFECT: reduced vibration of rotor and enhanced safety margin. 2 cl, 4 dwg
