ROTOR AND METHOD TO MANUFACTURE ROTOR OF ELECTRIC MACHINE Russian patent published in 2013 - IPC H02K1/27 H02K21/12 H02K15/03 

FIELD: electricity.

SUBSTANCE: method to manufacture a rotor (14) is proposed for an electric machine (13), including the following stages of its realisation: a) manufacturing of a magnetic element (8) by means of adhesion of permanent magnets (1, 1', 1", 1'") to each other with the help of the first glue, at the same time each permanent magnet (1, 1', 1", 1'") has one side (2) with the magnetic north (N) and one side (3) with the magnetic south (S), at the same time permanent magnets (1, 1', 1", 1'") when adhered are arranged so that sides of the magnetic north (N) or sides of the magnetic south (S) form a common lower side (3, 3', 3", 3'") of the magnetic element (8), at the same time the first glue in the hardened condition has the solid consistency; b) adhesion of the lower side of the magnetic element (8) with the yoke (12) with the help of the second glue, at the same time the second glue in the hardened condition is soft and elastic, which eliminates break of the second glue as the temperature of expansion of the magnetic element (8) and the yoke (12) increases. At the same time the yoke (12) in the place where the magnetic element (8) is adhered to the yoke (12), has the soft and elastic layer (2).

EFFECT: provision of rationality of rotor manufacturing process with permanent magnets with simultaneous provision of high reliability of permanent magnets fixation with closure on material of an electric machine rotor yoke.
