DEVICE FOR MAGNETIZING RING-SHAPED MAGNET FOR BLDC MOTOR |
| 摘要 |
Provided is a device for magnetizing a ring-shaped magnet for a brushless direct current (BLDC) motor, including: a rotor having a ring-shaped magnet installed on an outer peripheral surface of a rotor core; and a plurality of magnetizing yokes disposed so as to be spaced apart from each other by a predetermined interval while facing an outer peripheral surface of the ring-shaped magnet, magnetizing the ring-shaped magnet to form even-numbered unit magnets, and magnetizing the ring-shaped magnet only in regions except for one end and the other end of the unit magnets. |
