ROTARY ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JP2016082708
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a rotary electric machine which efficiently cools an inner rotor and a slide heating part supporting the inner rotor with a simple structure.SOLUTION: A rotary electric machine 100 includes: a housing 1; a rotary shaft 8 rotatably supported on the housing 1; an inner rotor 10; an outer rotor 20; rotation support members 21a, 21b supporting the outer rotor 20; a stator 30; a through hole 8a provided at the rotary shaft 8; a first bearing 32 provided between the inner rotor 10 and the housing 1; and a first insulation cover 11 covering the inner rotor 10. A guide groove 11b which guides a lubrication oil to the radial outer side of the inner rotor 10 is formed in the first insulation cover 11. A bending part 11c, which guides the lubrication oil so that the lubrication oil moves in an axial direction X, is formed in the guide groove 11b. The first bearing 32 and the bending part 11c are provided facing each other in the axial direction X.SELECTED DRAWING: Figure 2
