Abstract: A vibration and noise reduction motor, a rotor magnetizing structure of a motor, and a skew magnetizing yoke. The vibration and noise reduction motor includes a stator that is concentric with a shaft and axially fixed and a rotor including a rotor core configured to surround the stator and a plurality of block magnets disposed in the rotor core and configured to face the stator and surround the stator, where an air gap is provided between the plurality of block magnets and the stator, and each piece of the plurality of block magnets includes a plurality of poles and the plurality of block magnets are magnetized by a skew magnetizing yoke and has a continuous skew shape such that the plurality of poles provided for each piece are each inclined by a skew angle of the skew magnetizing yoke.
