Document Type and Number:
Japanese Patent JP2020145785
Kind Code:
A
Abstract:
To efficiently perform cooling in a rotary electric machine having a duct disposed in a core thereof.SOLUTION: A rotary electric machine 100 includes a rotor 10 having a rotor shaft 11 and a rotor core 12 in which an axial flow channel 12a and a plurality of rotor core ducts 12d are formed, a stator 20 having a stator core 21 which is disposed with a gap 18 from the rotor core 12 and in which a plurality of stator core ducts 21d are formed and a stator winding 22 including a stator winding conductor extending through a plurality of stator slots, a frame 40, coupling-side and non coupling-side bearings 30a, 30b, coupling-side and non coupling-side bearing brackets 45a, 45b, and an outdoor-air supply device 50. The rotor core 12 has an axial flow channel closing plate 12p for closing an end, of the axial flow channel 12a, opposed to an outlet space 40v. The frame 40 has a stator closing plate 40c for closing an end, of an annular flow channel 40f between the stator core 21 and the frame 40, opposed to an inlet space 40w.SELECTED DRAWING: Figure 1
