BODYLESS TRACTION ELECTRIC MACHINE Russian patent published in 2022 - IPC H02K5/20 H02K5/15 H02K5/173 H02K9/19 H02K9/22 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering. The bodyless traction electric machine (1) contains a stator (2) made of a plate core (3) and a rotor shaft (4) with a rotor (5) made of a plate core (6). The stator core (3) is located between two outer pressure plates (7, 8) and at least one screen (29, 30) of the bearing. Along the periphery section of the plate core (3) of the stator, at a distance from the plate core (3) of the stator, between the pressure plates (7, 8), there is at least one cover (9), made in the form of a stretching bar, to form at least one cooling chamber (10) with a base (17) on the surface of the plate core (3) of the stator. At least one intermediate space (11) between the base (17) and at least one cover (9) of the cooling chamber (10) is intended for the passage of the cooling fluid (K).

EFFECT: improvement in cooling.
