Title:
ROTARY ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JP2020014336
Kind Code:
A
Abstract:
To raise strength of a rotor of a rotary electric machine.SOLUTION: A rotary electric machine is provided with a stator (10) and a rotor (20). The rotor (20) forms through hole groups (100) consisting of a plurality of through holes (25) aligned in a circumferential direction in multilayer in a radial direction for every magnetic pole. The through holes (25) adjacent to each other in the through hole group (100) form R chamfers at ends facing each other. A minimum value (Rin) of dimensions of the R chamfers in the through holes (25) of each through hole group (100) is compared with a maximum value (Rout) of dimensions of the R chamfers in the through holes (25) of the through hole group (100) on an outer peripheral side of itself to make the minimum value (Rin) of the dimensions of the R chamfers of itself larger.SELECTED DRAWING: Figure 3
