<p>Some embodiments of the present disclosure provide a rotor of an electric brushless motor configured to be light weight and prevent vibrations generated during an operation of the motor to be transferred to the shaft of the rotor. The rotor comprises a shaft (4) elongated in a rotational axis, a single body magnet (1) comprising alternately magnetized portions, and a vibration absorption portion (3) interposed between the shaft (4) and single body magnet (1). The vibration absorption portion (3) absorbs vibrations generated during the operation of the motor and may comprise an elastic or a non-elastic material. The rotor further comprises a non-elastic portion (2) inhibiting the expansion of the vibration absorption portion (3) when the vibration portion is elastic.</p> |
