Abstract: An air-cooled motor is disclosed, comprising a motor shaft, a stator and a rotor which are disposed co-axially, said motor shaft being fitted with a fixed seat for supporting said stator and being operatably connected with said rotor and rotatably connected with said stator, said stator having a coil coupled to conductive wires; further comprising a front cover disposed at the front side of said rotor and having wind channels, wherein a front end portion of said rotor in the proximity of said front cover is provided with an air-inflow disk which has one or more air intake grooves each passing obliquely therethrough to form a windward angle relative to the rotation direction of said rotor; and said motor further comprises an air-exhausting disk which has one or more air outlet grooves each passing obliquely therethrough to form a windward angle relative to the rotation direction of said rotor.
