Abstract
An electrical rotating device includes a hollow cylindrical stator provided with a stator core and a stator coil, a rotor provided rotatably inside the stator, a case that houses the stator and the rotor, and a hollow cylindrical partition wall that is made of electrically conductive metal and partitions an interior space of the case into an inner space with respect to the stator and an accommodation space in which a coil end of the stator coil laterally protruding in an axial direction of a rotary shaft of the rotor from an end of the stator core is accommodated and liquid coolant is circulated. At least a portion of the partition wall close to the stator core is divided into plural small sections by forming plural slits.
