摘要： A rotating electrical machine according to the present invention includes: a rotor core (12) in which a slot (13) passing therethrough is provided; a rotor winding (14) which is placed in the slot (13) of the rotor core (12), and whose coil end portion is extended more on the axially outer side than the core end face (12a) of the rotor core (12); a U-shaped channel (15) which is arranged on the slot (13) of the rotor core (12), is touched to come into contact with a bottom portion of the rotor winding (14), and is axially extended to be projecting more on the axially outer side than the core end face (12a) of the rotor core (12); a slot cell (16) which is placed in the slot of the rotor core (12), and insulates the rotor winding (14) and the U-shaped channel (15) from the rotor core (12); and an interposed piece (17) arranged between the rotor windings (14) at a portion more projecting than the core end face (12a) of the rotor core (12). The projecting end face (12a) of the U-shaped channel (15) is arranged more on the axially inner side than the projecting end face (17a) of the interposed piece (17).
