Title:
かご形誘導回転電機の設計方法
Document Type and Number:
Japanese Patent JP7209638
Kind Code:
B2
Abstract:
A squirrel-cage induction rotating electrical machine comprises: a solid rotor, a stator, and bearings. The solid rotor includes a shaft part, a columnar-shaped rotor core part (13) integrally formed with the shaft part and having rotor slots (14) formed therein, and a plurality of conductor bars (16) passing through the respective rotor slots (14) and coupled together at both axial ends outside the rotor core part. The stator includes a cylindrical stator core (21) provided radially outside the rotor core part (13), and stator windings passing through a plurality of respective stator slots (22) which are formed in the radially inner surface of the stator core. An outer wall (14a) and an inner wall (14b) of each rotor slot (14) are tilted at a predetermined angle or more with respect to a plane including a rotation axis of the shaft part.
