Abstract | The utility model provides a rotor of a motor, a motor, and an air conditioner. The rotor comprises a yoke, a resin magnet portion, a magnet for position detection, brackets, and a bracket connecting portion. The yoke is in a cylinder shape. Resin magnets are formed at the periphery of the yoke in an integrated mode to form the resin magnet body. The magnet for position detection is configured at one axial end portion side of the resin magnet portion. The multiple brackets are formed at the axial end surface of one side, with the magnet for position detection, of the yoke; each bracket has one pair of protruding portions and an opening portion formed between the protruding portion. The multiple brackets are formed at the upper surface of the bracket connecting portion. The resin magnets are provided for non-removing portions of rib-shaped flow channels of the resin magnet portion through the opening portions; and the opening portions are buried and thus the bracket portions for carrying the magnet for position detection are formed based on the brackets. And magnet holding protrusions for holding the magnet for position detection are arranged at the bracket portions. Therefore, the brackets can be formed easily and the rotor quality can be improved. Moreover, the needed amount of the resin magnets can be reduced, thereby realizing the low cost effect. |
