Title:
ROTOR AND PERMANENT MAGNET MOTOR
Document Type and Number:
Japanese Patent JP2015126655
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a rotor the vibration proofness of which can be enhanced without changing the size of the rotor, and to provide a permanent magnet motor.SOLUTION: In a rotor 1 including a shaft 2, an inner peripheral side core 3 fixed to the shaft 2, a columnar buffer member 4 covering the inner peripheral side core 3, and a cylindrical permanent magnet 5 covering the outer periphery of the buffer member 4, the inner peripheral side core 3 has a plurality of inner peripheral side core pieces 31 having a predetermined gap S in the axial direction of the shaft 2 and perpendicular thereto, and the buffer member 4 covers the inner peripheral side core pieces 31 so as to fill the predetermined gap S. A permanent magnet motor includes the rotor 1, and a stator arranged to face the outer peripheral side of the rotor 1 at a predetermined interval (air gap).
