Claims

[Scope of utility model registration request]

A stator core is provided on the inner periphery of the outer frame via a core back ventilation passage and has a plurality of ventilation holes penetrating in the axial direction, and a predetermined gap is provided on the inner periphery of the stator core. In a kite cooling device for a rotating electric machine, the rotor core is disposed through the rotor core and fitted to the rotor shaft, and the cooling fan fixed to the rotor shaft performs ventilation cooling. A partition plate that is attached to the intermediate portion and blocks off the ventilation hole is in contact with the upstream and downstream surfaces of the partition plate so that the ventilation Rokkichi core back ventilation passages communicate with each other, and A spacer piece is arranged so that an exhaust passage is formed on the upstream side of the partition plate and an intake passage is formed on the downstream side, and a spacer piece is provided in the core back ventilation passage and has an opening on the upstream side of the exhaust passage. A ventilation cooling arrangement for a rotating electrical machine, comprising: an air guide pipe communicating with the air intake passage;
