Motor and washing machine with the same mounted therein

A motor comprising:

• a stator;
• a rotor rotatably disposed around the stator;
• and
• a rotor cup having cooling-holes formed at the bottom part thereof for allowing external air to flow into the inside of the rotor cup therethrough, and lower blades formed at the bottom part thereof for generating a blowing force, the rotor being fixed to the rotor cup at the inner circumference thereof,
• wherein the rotor is provided at the upper side thereof with upper blades for supplying external air to the upper part of the rotor when the rotor is rotated.
