[0014] [Structure of rotating electric machine]
[0015] figure 1 is a schematic diagram showing the configuration of the rotating electric machine 10 . figure 2 yes figure 1 A magnified view of part A of the box. The rotary electric machine 10 has a stator 12 and a rotor 14 . The stator 12 has a substantially cylindrical stator core 20 made of iron-based metal. The stator core 20 has a plurality of teeth 22 protruding inward in the circumferential direction, and a coil 24 is wound around each tooth 22 .
[0016] The rotor 14 has a substantially cylindrical rotor core 30 formed of laminated steel plates in which thinner steel plates are laminated in the rotation axis O direction. A shaft insertion hole 32 penetrating through the rotating shaft O is formed in the rotor core 30 . A rotor shaft 34 is inserted into the shaft insertion hole 32 by shrink fitting. Accordingly, the rotor core 30 rotates integrally with the rotor shaft 34 . The rotor core 30 has a plurality of...
Deformed example 1
[0042] In the first embodiment, the first socket 40 and the second socket 42 are separated at the endpoints P1, P1, but the first socket 40 and the second socket 42 may be in contact with each other at the endpoints P1, P1. Figure 5 yes figure 1 A magnified view of part A of the box. Such as Figure 5 As shown, the communicating portion 44 is formed in a substantially isosceles triangle when the rotor core 30 is viewed from the direction of the rotation axis O. As shown in FIG. At this time, when the rotor core 30 is viewed from the direction of the rotation axis O, the side surfaces 44b connecting the end points P2 and P2 of the communicating portion 44, the short sides 50a on the inner peripheral sides of the first permanent magnet 50 and the second permanent magnet 52, 52a forms a substantially isosceles triangle space.
Deformed example 2
[0044] In the first embodiment, the first permanent magnet 50 and the second permanent magnet 52 are formed to have substantially the same length as the length of the first slot 40 and the second slot 42 when viewed from the direction of the rotation axis of the rotor core 30 , but the first permanent magnet 50 and the second permanent magnet 52 may be formed shorter than the length of the first slot 40 and the second slot 42 .
[0045] [Technical idea obtained from the embodiment]
[0046] The following describes technical ideas that can be grasped from the above-described embodiments.
[0047] The rotor 14 has: a rotor core 30 that rotates integrally with the rotor shaft 34; a first slot 40 and a second slot 42 that pass through the rotor core 30 in the direction of the rotation axis O; When viewed in the O direction, it is formed into a substantially rectangular shape, and is arranged in a V-shape in which the outer peripheral sides are separated from each other and the in...
