ROTOR, METHOD OF MANUFACTURING THE ROTOR, AND ROTARY ELECTRIC MACHINE HAVING THE ROTOR |
| 摘要 |
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. |
