Abstract
A rotor of a rotary electric machine includes a rotor core. The rotor core is a stacked body in which a plurality of electromagnetic steel sheets are stacked. The electromagnetic steel sheet includes an inner annular portion and an outer annular portion. A first insertion hole into which a rotating shaft is inserted is formed in the inner annular portion. A rotor inner diameter is defined as twice a distance from a center of the first insertion hole to an inner circumferential edge of the inner annular portion. A rotor outer diameter is defined as twice a distance from the center of the first insertion hole to an outer circumferential edge of the outer annular portion. A ratio of the rotor inner diameter to the rotor outer diameter is within a range of 1:1.5 to 1:3.5.
