Title:
ELECTRIC ROTATING MACHINE
Document Type and Number:
Japanese Patent JP2011135699
Kind Code:
A
Abstract:

To provide a rotating electric machine capable of maintaining cooling performance of a coil end portion, even if the rotating electric machine is inclined in a specified direction, while suppressing the cost at a low level.

The rotating electric machine M includes a rotor 8 freely rotatable about an axis of rotation; a stator 6 having a plurality of slots facing the circumferential surface of the rotor 8; coils C1 wound on each of the plurality of slots; and a coil end portion 1, as a region where the coils C1 protrude from the end position of the axial direction of the stator 6 in the axial direction. Furthermore, the rotating electric machine M includes a pump 10 (cooling liquid supply portion) etc. for supplying a cooling liquid; and a cylinder 3 for making the cooling liquid supplied from the pump 10, and so on, flow inside and is provided in the vicinity of the upper part of the stator 6 substantially parallel to the rotation shaft of the rotor 8. Since the rotating electric machine has a plurality of discharge ports 4 having different discharge direction for discharging the cooling liquid, the cooling performance of the coil end portion 1 can be maintained and improved. Since the rotating electric machine is realized by a simple constitution, manufacturing cost is suppressed at a low level.
