FIELD: electric engineering.
SUBSTANCE: proposed eccentroid electric machine comprises (dwg. 1-2) body (1) arranged with internal ring in the form of elliptic bearing race (2) from dielectric material, stator made in the form of three inertial elements (3), every of which is assembled from plates of electrotechnical steel, comprises axis (4) of rotation, is arranged in the form of rolls equipped with magnetic belts (5) at the ends, which consist of even number of semirings of various polarity. Axis (4) of rotation of each of inertial elements (3) is connected by two telescopic spring links (6) to dampers (7), installed symmetrically on both sides of rotor system, including propeller blades (8), on driving shaft (9) common for stator and rotor, which is arranged eccentrically relative to geometric axis of eccentroid electric machine. Body (1) is closed with two covers (10) at sides, on which at inner sides there are elliptic angle guide elements (11) installed to form together with elliptic bearing race (2) elliptic closed channel for movement of inertial elements (3) in it. Telescopic spring links are arranged relative to each other at the angle of 120°. Rotor system of eccentroid electric machine (dwg. 3-7) consists of two rotors: rotor (12) of free rotation and rotor (13) of forced rotation, rigidly arranged on driving shaft (9). Rotor (12) of free rotation comprises hollow shaft (14) arranged on sliding bearings (15) concentrically relative to both driving shaft and rotor (13) of forced rotation. Inside hollow shaft (14) of ferromagnetic material there is a system arranged from even number of permanent magnets (16) with alternating poles, and outside their rims (17) - magnetic belts (18) made also of even number of permanent magnets. Magnetic belts (5) and (18) of stator and rotor (12) of free rotation are arranged oppositely, and permanent magnets (16) have length comparable to length of rotor (13). Each of dampers (7) comprises hollow cylindrical perforated ring (21), rigidly fixed on driving shaft (9) and divided with internal radial partitions (23), between which compensation springs (24) are installed with thrust. Ends of telescopic spring links (6) arranged in dampers are arranged with hubs (22) rigidly installed on driving shaft (9), are installed in middle part of compensation springs and come out of dampers through holes in their cylindrical rings.
EFFECT: increased efficiency of electric machine operation by provision of ability to generate additional energy used for self-sufficiency of machine operation in rated mode and for supply to loads, and for production of traction used to provide for ability to use electric machine as propeller.
