Abstract: A rotor manufacturing method for manufacturing a rotor including a rotor core, the rotor core having a permanent magnet mounted thereon throughout a circumferential direction, includes covering an outer circumference of the rotor core with a tubular rotor cover; and forming an angular portion conforming to an outer shape of the permanent magnet by pressing an open end of the rotor cover radially inward with use of a pressing member, the open end of the rotor cover axially projecting from an end of the rotor core before being pressed.

Abstract: A rotor 2 includes a rotor core 21 fixed to a rotation axis in such a manner that the rotor core 21 is rotatable integrally with the rotation axis, the rotor core 21 being configured to have a plurality of magnets 22 mounted thereon throughout a circumferential direction; a first rotor cover 24 that includes a first tubular portion 26, the first tubular portion 26 having a tubular shape configured to cover an outer circumference of one axial side of the rotor core 21; and a second rotor cover 25 that includes a second tubular portion 28, the second tubular portion 28 having a tubular shape configured to cover an outer circumference of the other axial side of the rotor core 21. An outer diameter of the first tubular portion 26 is configured to be larger than an inner diameter of the second tubular portion 28, and the first rotor cover 24 and the second rotor cover 25 are configured to be fixed to each other by press fitting to have the first tubular portion 26 arranged at an inner circumferential side of the second tubular portion 28.
