[0065] First, refer to figure 1 and figure 2 , the configuration of the rotor 1 according to the first embodiment will be described. figure 1 It is a figure which shows the structure of the rotor 1 of 1st Embodiment. figure 2 It is a figure which shows the structure of the rotor core unit 2 of 1st Embodiment. In the following, for the convenience of explanation, sometimes figure 1 The state of the rotor 1 shown is referred to as the "assembled state".
[0066] The rotor 1 of the first embodiment is, for example, a rotor portion of a rotating electrical machine used as a driving source for electric vehicles, hybrid vehicles, or a generator. Specifically, the rotor 1 constitutes a rotating electric machine together with a cylindrical stator (not shown) provided around the rotor 1 .
[0067] Such as figure 1 As shown, the rotor 1 includes: a rotor core unit 2, a pair of end plates 4 arranged to be in contact with both end surfaces of the rotor core unit 2, a sh...

[0129] Next, refer to Figure 10 to Figure 14 , the rotor manufacturing method of the second embodiment will be described. Figure 10 It is a flowchart of the rotor manufacturing method of 2nd Embodiment. Figure 11 is true Figure 10 The diagram of step S20 is described. Figure 12 is true Figure 10 The diagram of step S30 is described. Figure 13 is true Figure 10 The diagram of step S40 is described. Figure 14 is true Figure 10 The diagram of step S50 is described. It should be noted, Figure 11 to Figure 14 The illustration of a part of the magnet hole 21 and the magnetizing magnet 31 is omitted. Furthermore, for ease of observation, Figure 11 to Figure 14 The magnetized magnet 31 and the non-magnetic guide rail 50 are indicated by solid lines.
[0130] In the following description, the description of the items common to the first embodiment related to the second embodiment will be omitted, and the contents of the differences will be described. In particul...
no. 3 approach
[0151] Next, refer to Figure 15 to Figure 19 , the rotor manufacturing method of the third embodiment will be described. Figure 15 is a flowchart of the rotor manufacturing method of the third embodiment. Figure 16 is true Figure 15 The diagram of step S20 is described. Figure 17 is true Figure 15 The diagram of step S30 is described. Figure 18 is true Figure 15 The diagram of step S40 is described. Figure 19 is true Figure 15 The diagram of step S50 is described. It should be noted, Figure 16 to Figure 19 The illustration of some magnet holes 21 is omitted. Furthermore, for ease of observation, Figure 16 to Figure 19 The magnetized magnet 31 and the non-magnetic guide rail 50 are indicated by solid lines.
[0152] (First rotor core 20A and second rotor core 20B)
[0153] Such as Figure 16 As shown, the second laminated thickness of the second rotor core 20B of the third embodiment is 1 / 2 of the second laminated thickness of the second rotor core 20B ...
