Document Type and Number:
Japanese Patent JP3576295
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide the rotor of a motor equipped with balancing structure which can surely modify the unbalance of the rotor without executing the machining to the rotor. SOLUTION: This rotor 10 is equipped with a plurality of permanent magnets 18 fixed to the tubular surface 16 of a rotor core 14 having a shaft 12d. Between permanent magnets 18 adjacent in circumferential direction, a groove 28 is demarcated by the tubular surface 16 of the rotor core 14 and the side face 24 of each permanent magnet 18. The tubular member 30 fixes a plurality of permanent magnets 18 into the specified position on the tubular surface 16 of the rotor core 14. In the groove 28, a balancing member 34 to modify the unbalance of the rotor 10 is arranged. The balancing member 34 is made by hardening the resin material charged in the specified position of the groove 28. The tubular member 30 supports the balancing member 34 in the specified position within the groove 28, resisting the centrifugal force working at the time of rotation of the rotor 10.
