摘要：PURPOSE:To improve the strength against the circumferential stress by forming a projection engaged in a circumferential direction by bending a slit for coupling an outer slot and an inner slot between the outer slot and the inner slot.
ikan
CONSTITUTION:Projections 8, 9 and 10, 11 to be engaged in a circumferential direction by bending a slit 4 for coupling an outer slot 2 with an inner slot 3 in a dovetail shape are formed, and aluminum or its alloy is, for example, cast as an inner conductor 6 as a nonmagnetic intermediate material 7 entirely in the slit 4. When thus constructed, even if strong circumferential stress is applied due to high speed rotation, the material 7 between the projections 8, 9 and 10, 11 and the engaging surfaces 8a, 9a and 10a, 11a is narrowed to be rigidly engaged. Accordingly, no deformation such as opening of the slots 2, 3 and the slit 4 does not occur.
