Document Type and Number:
Japanese Patent JP2019106773
Kind Code:
A
Abstract:
To provide a rotor in which an interference of a cover cylinder is uniform in an axial direction.SOLUTION: A rotor 30 comprises: a rotary cylinder 31 which is mounted to a rotary shaft of which the outer peripheral surface is tapered, and of which the inner peripheral surface is tapered; a permanent magnet 32 which is disposed at an outer peripheral side of the rotary cylinder 31; and a cover cylinder 33 which is mounted at an outer peripheral side of the permanent magnet 32 and covers the permanent magnet 32. The rotor is configured in such a manner that, as an outer diameter of a laminate S consisting of the rotary cylinder 31 and the permanent magnet 32 is reduced in a tapered shape in an axial direction X, an interference of the cover cylinder 33 with respect to the laminate S is enlarged in a tapered shape in the axial direction X.SELECTED DRAWING: Figure 3B
