Title:
DYNAMO-ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2017/082023
Kind Code:
A1
Abstract:
A dynamo-electric machine is configured so that a stator and a coil can be efficiently cooled while the flow rate of cooling liquid is reduced. This dynamo-electric machine (1) is provided with a rotating shaft (2), a rotor (3) which is provided to the rotating shaft (2), a stator (4), and a housing (5). The stator (4) has a stator core (16) disposed on the outer periphery of the rotor (3), and also has a coil (17) wound on the stator core (16) and having end coils (17a, 17b) exposed from the stator core (16) in the direction of the axis of the rotating shaft (2). A housing (5) rotatably supports the rotating shaft (2), has accommodated therein the rotor (3) and the stator (4), and has a serial housing flow passage (28) formed in the inner wall surface of the housing (5), the serial housing flow passage (28) allowing cooling liquid for cooling the outer periphery of the stator core (16) and the end coils (17a, 17b) to flow therethrough.
