description The invention is characterized in that in a motor rotor constituted by a motor shaft (30), a permanent magnet (31) surrounding the motor shaft (30) around an axis, a pair of end rings (32, 32) surrounding the motor shaft (30) around the axis and pinching the permanent magnet (31) from both sides in an axial direction, and a hollow cylindrical outer sleeve (33) surrounding the permanent magnet (31) and a pair of end rings (32, 32) in a fastening state around the axis, one end portion or both end portions of the outer sleeve (33) protrudes in the axial direction than an end surface of the end ring (32). A rotating balance correction is executed by pruning away a part of the protruding portion.
