Rotor for synchronous motor |
摘要 |
A rotor (10) includes a plurality of permanent magnets (14) disposed around a shaft (12) at generally equal intervals, and a plurality of laminated core members (16) disposed between the permanent magnets (14) so as to form magnetic poles. The laminated core members (16) are formed by stacking a plurality of core-laminations (26) made of magnetic materials and an integral core-lamination, and joining them to each other. The integral core-lamination includes a plurality of core-lamination sections each having a shape the same as that of the core-lamination (26), and connecting portions (46) for connecting adjacent core-lamination sections with each other. When the large number of core-laminations (26) and the integral core-lamination are integrally joined by a press-fitting process, the laminated core members (16) are connected with each other in such a relative arrangement of a finished assembly that a space for locating the permanent magnet (14) is defined between the adjacent laminated core members (16), and thus an integral laminated rotor core (48) is formed.
