A motor with a built-in cooling fan includes: a rotor which includes a magnet; a stator which includes a stator core which surrounds the rotor and a coil which is wound around the stator core; and a cooling fan which includes a cooling fan body which is arranged on the end of the rotor and cooling wings which are arranged on the frame of the cooling fan body and are vertical to the cooling fan body. The height of the cooling wing measured from the cooling fan body is 18 to 22 mm. The cooling wing is inclined to the inside of the cooling fan based on a tangent line of the frame of the cooling fan body at 4 to 6 degrees. The number of the cooling wings is 9 to 12. |
