Abstract

A rotor includes: a rotor core (131) formed by layering a first plate-shaped member (131A) and a second plate-shaped member (131B) and having a first magnet insert hole (1311) and a second magnet insert hole (1312) arranged at an outer position than the first magnet insert hole (1311) in the radial direction; a magnet (132) inserted in the first and the second magnet insert holes (1311, 1312); anda resin portion (133) filling the first and the second magnet insert holes (1311, 1312). The first plate-shaped member (131A) has a first hole portion (1311A) and a second hole portion (1312A) whichrespectively constitute the first and the second magnet insert hole (1311, 1312). The second plate-shaped member (131B) has a portion positioned at least at one end of the rotor core (131) in the axial direction and covering a part of the first hole portion (1311A).

Description

technical field [0001] The present invention relates to a rotor, a method for manufacturing the same, and an electric vehicle, and more particularly, to a rotor included in a rotary electric machine, a method for manufacturing the same, and an electric vehicle including the rotor. Background technique [0002] Japanese Unexamined Patent Publication No. 2005-184968 (Patent Document 1) describes a rotor having a rotor core made of a plurality of electromagnetic steel sheets. Here, the plurality of electrical steel sheets include at least one first steel sheet arranged at the endmost portion and second steel sheets arranged other than that. In addition, each of the plurality of electromagnetic steel sheets has a magnet hole provided to form a magnet attachment hole. Also, the magnet hole of the first steel plate is formed smaller than the magnet hole of the second steel plate. [0003] When embedding the magnets in the rotor core, the magnets are inserted into the magnet inse...
